Hawaii ( /həˈwaɪ.i/ ⓘ hə-WY-ee; Hawaiian : HawaiʻiHawaiian pronunciation: [həˈvɐjʔi] ) is the largest island in the United States, located in the eponymous state of Hawaii. It is the southeasternmost of the Hawaiian Islands, a chain of volcanic islands in the North Pacific Ocean. With an area of 4,028 square miles (10,430 km2), it has 63% of the Hawaiian archipelago's combined landmass. However, it has only 13% of the archipelago's population. The island of Hawaiʻi is the third largest island in Polynesia, behind the north and south islands of New Zealand. [2]
The island is often referred to as the Island of Hawaii or Hawaii Island to distinguish it from the state. It is also referred to as The Big Island, due to its size relative to the other islands. In Hawaiian, the island is sometimes called Moku o Keawe. The word keawe has several meanings. One definition, "southern cross", is said to be the name of an ancient chief. [3] Another definition is "the bearer" (ke-a-we). [4] Hawaii County is the local administrative unit.
As of the 2020 census, the population was 200,629. [5] The county seat and largest town is Hilo. Hawaiʻi County has no incorporated cities. [6]
Hawaii is allegedly named after Hawaiʻiloa, a legendary Polynesian navigator who is said to have discovered the island. Other accounts attribute the name to the legendary realm of Hawaiki, a place from which some Polynesians are said to have originated, the place where they transition to in the afterlife, or the realm of the gods and goddesses. The indigenous Hawaiian name of the island was originally rendered and published as "Owyhee" or "Owhyhee".
It is uncertain when Hawaii was first discovered by humans. Early archaeological studies suggested that Polynesian explorers from the Marquesas Islands or Society Islands may have arrived in the Hawaiian islands as early as the 3rd century CE, [7] possibly with a second wave arriving from Tahiti around 1100 CE. [8] However, more recent analyses suggest that the first settlers arrived around 900–1200 CE. [9]
Oral tradition holds one of the most famous aliʻinui of Hawaii to be ʻUmi-a-Līloa, who united the island by force. [10] He was the illegitimate son of Līloa, aliʻinui of Hawaii who ruled from Waipio Valley in the Hamakua district. When Līloa died, the island passed to ʻUmi's half-brother Hakau. However, ʻUmi attacked and killed Hakau along with the aliʻi who served him, winning control of Hamakua. He then proceeded to conquer the rebelling districts of Hilo, Puna, Kau, and Kona. He placed the seat of his new government in Kailua in the Kona district. [11]
In 1779, Captain Cook made his second voyage to the Hawaiian islands, anchoring in Kealakekua Bay on the island of Hawaii. He spent several weeks there, meeting and trading with locals and readying his ships for a planned trip to the Arctic. The Hawaiians received him hospitably, considering him to be an incarnation of the god Lono. Early in 1780, Cook departed. However, his ships were damaged in a storm immediately after setting sail, and he was forced to return to Kealakekua after only a week at sea. During this second anchoring, an altercation between the Europeans and the Hawaiians turned violent, resulting in the death of multiple people on both sides, including Cook himself. Peaceful relations were eventually restored with the crew of his ships, who departed for good later that month. [12] : 15–20
In 1780 CE, the island of Hawaii was controlled by the aliʻinui Kalaniʻōpuʻu, a descendant of ʻUmi-a-Līloa. On his death in 1782, he designated his son Kīwalaʻō as his heir. However, a feud between Kīwalaʻō and Kalaniʻōpuʻu's nephew Paiʻea Kamehameha soon escalated into a civil war. Kīwalaʻō was killed in the Battle of Mokuʻōhai later that same year, leaving control of the island divided between Kamehameha in the west, Kīwalaʻō's uncle and advisor Keawemaʻuhili in the northeast, and Kīwalaʻō's half-brother Keōua Kūʻahuʻula in the south. The three chiefs, aided by Western ships and weapons, fought to a standstill for eight years until 1790, when Keōua defeated and killed Keawemauhili. In 1791 Kamehameha's men killed Keōua at a diplomatic meeting, leaving control of Hawaii to Kamehameha. [12] : 32–38
Kamehameha went on to conquer the rest of the Hawaiian islands, consolidating his control in 1810 with the peaceful surrender of Kaumualiʻi, king of Kauai. [12] : 47-60 He gave his new kingdom, and by extension the island chain itself, the name of his native island – the Kingdom of Hawaii. [13]
In 1822, missionary William Ellis arrived and was one of a party that completed a tour of the island, descriptions of which were later published in his journal. [14]
In July, 1898, Hawaii and all the Hawaiian islands were annexed by the United States, becoming the Territory of Hawaii. In 1905, the passage of the County Act established the County of Hawaii, providing the island with local government for the first time since 1810. [15]
According to the U.S. Census Bureau, the county has a total area of 5,086 square miles (13,170 km2), of which 4,028 sq mi (10,430 km2) is land and 1,058 sq mi (2,740 km2) (20.8%) is water. [16] The county's land area comprises 62.7 percent of the state's land area. It is the highest percentage by any county in the United States. Delaware's Sussex County comes in second at 48.0 percent, while Rhode Island's Providence County is third at 39.6 percent.
At its greatest dimension, the island is 93 miles (150 km) across. Measured from its sea floor base to its highest peak, Mauna Kea at 10,000 metres (33,000 ft) is the world's tallest mountain, taller than even Mount Everest, since the base of Mount Everest is above sea level. [17]
The most southern point of Hawaii, Ka Lae, is the southernmost point of the United States. The nearest landfall to the south is the Line Islands. To the northwest of the island of Hawaii is the island of Maui, whose Haleakalā volcano is visible from Hawaii across the Alenuihaha Channel.
The island of Hawaiʻi is built from five separate shield volcanoes that erupted somewhat sequentially, one overlapping the other. These are (from oldest to youngest): [18]
Geological evidence from exposures of old surfaces on the south and west flanks of Mauna Loa led to the proposal that two ancient volcanic shields (named Ninole and Kulani) were all but buried by the younger Mauna Loa. [19] Geologists now consider these "outcrops" to be part of Mauna Loa.
Based on geochemical (including trace elements) and isotope differences in their eruptive products, Hawaiian volcanoes fall into two families. The differences are believed due to their separate magma systems. Hualālai and Mauna Loa are members of one family, while Kohala, Mauna Kea, and Kilauea are members of the other. [20]
Because Mauna Loa and Kīlauea are active volcanoes, the island is growing. Between January 1983 and September 2002, lava flows added 543 acres (220 ha) to the island. Lava flowing from Kīlauea destroyed several towns, including Kapoho in 1960 and again in 2018, and Kalapana and Kaimū in 1990. In 1987 lava filled in "Queen's Bath", a large, L-shaped, freshwater pool in the Kalapana area. [21] Another 875 acres were added between May and July 2018 by the 2018 lower Puna eruption. [22] [23] Mauna Loa erupted in 2022, 38 years after the prior activity. [24]
Some geologists also count two undersea volcanoes in the base of the island. [25] Māhukona off the northwest corner of the island has eroded below the ocean surface. [26] Kamaʻehuakanaloa (formerly Lōʻihi) is under water 22 miles (35 km) southeast of Hawaii. It is an erupting seamount that has grown to reach 3,200 feet (980 m) below the ocean surface, and it is forecast to break the surface in 10,000 to 100,000 years. [27]
The Great Crack is an eight-mile-long (13,000 m), 60-foot-wide (18 m) and 60-foot-deep (18 m) fissure in the island, in the district of Ka'u. According to the United States Geological Survey (USGS), the Great Crack is the result of crustal dilation from magmatic intrusions into the southwest rift zone of Kilauea. [28] While neither the earthquake of 1868 nor that of 1975 caused a measurable change in the Great Crack, lava welled out of its lower 6 miles (10 km) in 1823. [28]
Trails, rock walls, and archaeological sites from as old as the 12th century exist near the Great Crack. In August 2018, the National Park Service purchased nearly 2,000 acres (810 ha) of private land adjacent to Hawaii Volcanoes National Park, claiming that the area had important geological features to be studied and preserved. [29]
The Hilina Slump is a 4,760-cubic-mile (19,800 km3) section of the south slope of Kīlauea that is moving away from the island. Between 1990 and 1993, Global Positioning System (GPS) measurements showed a southward displacement of about 4 inches (10 cm) per year. [30] Undersea measurements show a "bench" that has formed a buttress and that this buttress may tend to reduce the likelihood of catastrophic detachment. [31] [32]
On 2 April 1868, an earthquake with a magnitude estimated between 7.25 and 7.9 rocked the southeast coast of Hawaii. This was the most destructive earthquake in the Hawaii's recorded history. [33] It triggered a landslide on Mauna Loa, 5 miles (8 km) north of Pahala, killing 31 people. A tsunami claimed 46 more lives. The villages of Punaluʻu, Nīnole, Kawaʻa, Honuʻapo, and Keauhou Landing were severely damaged. The tsunami reportedly rolled over the tops of the coconut trees up to 60 feet (18 m) high, and it reached inland a distance of a quarter of a mile (400 meters) in some places. [34]
On 29 November 1975, a 37-mile-wide (60 km) section of the Hilina Slump dropped 11.5 feet (3.5 m) and slid 26 feet (7.9 m) toward the ocean. This movement caused a 7.2 magnitude earthquake and a 48-foot-high (15 m) tsunami. Oceanfront property was washed off its foundations in Punaluu. Two deaths were reported at Halape, and 19 other people were injured. [35]
The island suffered damage from a tsunami caused by earthquakes in Alaska on 1 April 1946, and in Chile on 23 May 1960. Downtown Hilo was damaged by both tsunamis, with many lives lost. Just north of Hilo, Laupāhoehoe lost 16 schoolchildren and five teachers in the tsunami of 1946. [36]
In March 2011, a 9.0 magnitude earthquake off the east coast of Japan again created a tsunami that caused minor damage in Hawaii. The estimated damage to public buildings was about US$3 million. [37] In the Kona area this tsunami washed a house into Kealakekua Bay, destroyed a yacht club and tour boat offices in Keauhou Bay, caused extensive damage in Kailua Kona, flooded the ground floor of the King Kamehameha Hotel, [38] and temporarily closed the Kona Village Resort. [39]
In early May 2018, hundreds of small earthquakes were detected on Kīlauea's East rift zone, leading officials to issue evacuation warnings. On 3 May 2018, the volcano erupted in Puna after a 5.0 earthquake earlier in the day, causing evacuations of Leilani Estates and Lanipuna Gardens subdivisions. [40] [41] A seemingly related 5.3 magnitude quake and a subsequent 6.9 magnitude earthquake occurred on 4 May. [42] [43]
Vog (volcanic fog) can envelop the island of Hawaii when Kilauea is active. Since the termination of volcanic activity in September 2018, vog has largely disappeared on the west side of the island. [44] The gas plumes created a blanket of vog that the trade winds mostly deflect toward the Kona coast. Vog can damage the health of plants, humans, and other animals. Most of the aerosols are acidic and of a size where they can remain in the lungs to damage them. Flu-like symptoms and general lethargy are reported, and are especially pronounced in people with respiratory conditions. [45] [46] [47] [48]
The island hosts many specialized ecosystems/microclimates, including many protected by federal designation:
Sugarcane was the backbone of the island economy for more than a century. In the mid-20th century, sugarcane plantations began to downsize, and in 1995 the island's last plantation closed. [49]
Most of the island's economy depends on tourism, centered primarily in resort areas on the western coast of the island in the North Kona and South Kohala districts. Sustainable tourism is increasing. [50]
Diversified agriculture is a growth sector. Major crops include macadamia nuts, papaya, flowers, tropical and temperate vegetables, aquaculture, and coffee beans. The island's orchid production is the state's largest. [51] The island is home to one of the United States' largest cattle ranches: Parker Ranch, on 175,000 acres (708 km2) in Waimea.
The island is known for astronomy, with numerous telescopes positioned on the summit of Mauna Kea at the Mauna Kea Observatories, where atmospheric clarity is excellent and little light pollution intrudes. [52] Astronomy has become somewhat controversial, given accusations of mismanagement by the observatory manager, the University of Hawaii. The proposed addition of the Thirty Meter Telescope generated protests that stalled the project and led to the transfer of management responsibility to a Governor-appointed body. [53]
NELHA (Natural Energy Laboratory of Hawaii Authority), a 675-acre (273 ha) state developed site, is a green economic development ocean science and technology park on the west side of the island. It provides resources and facilities for energy and ocean-related research, education, and commercial activities in an environmentally sound and culturally sensitive manner. Business tenants on this coastal site include microalgae farms, aquaculture, solar technology and marine biotech. Tenants have access to three sets of pipelines delivering deep-sea water from a depth of up to 3,000 feet (910 m), as well as pristine sea surface water and almost constant sunshine. A 2012 study by the University of Hawaiʻi Economic Research Organization reported that the total economic impact of activities at NELHA was $87.7 million and created 583 jobs. [54]
Three routes connect the two major towns, Hilo on the east coast and Kailua-Kona on the west coast: [55]
State highways 270 (Kawaihae – Hawi) and 180 (the "Kona coffee road", connect Honalo to State highway 190), South Point Road (Highway 11 to South Point), etc.
The three Hawaii Scenic Byways are:
Rental car offices are at the international airports. Taxi service is also available. Island-wide bus service is provided by the Hele-On Bus. [56]
Two commercial airports serve Hawaiʻi Island:
The private airports are:
The major commercial ports are Hilo on the east side and Kawaihae on the west side. Cruise ships often stop at Kailua-Kona (90 times in 2017) [57] and Hilo (108 times in 2017). [58]
The larger hotels on the east coast are:
The larger hotels on the west coast, from north (Puako) to south (Captain Cook):
Hilo is the largest settlement in and the county seat of Hawaiʻi County, Hawaii, United States, which encompasses the Island of Hawaii, and is a census-designated place (CDP). The population was 44,186 according to the 2020 census. It is the fourth-largest settlement in the state of Hawaii, the largest settlement in the state outside of Oahu, and the largest settlement in the state outside of the Greater Honolulu Area.
Kailua-Kona is an unincorporated community and census-designated place (CDP) in Hawaii County, Hawaii, United States. It's most commonly referred to simply as Kona, but also as Kona Town, and occasionally as Kailua, thus its less frequent use. Kailua-Kona is the second-largest settlement on the island of Hawaii and the largest on the island's west side, where it is the center of commerce and the tourist industry. Kailua-Kona is served by Kona International Airport, just to the north in the adjacent CDP of Kalaoa. The population was 19,713 at the 2020 census, up from 11,975 at the 2010 census.
The Hawaiian Islands are an archipelago of eight major volcanic islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some 1,500 miles from the island of Hawaiʻi in the south to northernmost Kure Atoll. Formerly called the Sandwich Islands by Europeans, the present name for the archipelago is derived from the name of its largest island, Hawaiʻi.
Mauna Loa is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaii in the Pacific Ocean. Mauna Loa is Earth's largest active volcano by both mass and volume. It was historically considered to be the largest volcano on Earth until Tamu Massif was discovered to be larger. Mauna Loa is a shield volcano with relatively gentle slopes, and a volume estimated at 18,000 cubic miles (75,000 km3), although its peak is about 125 feet (38 m) lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and tend to be non-explosive.
Mauna Kea is a dormant shield volcano on the island of Hawaiʻi. Its peak is 4,207.3 m (13,803 ft) above sea level, making it the highest point in Hawaii and the island with the second highest high point, behind New Guinea, the world's largest tropical island with multiple peaks that are higher. The peak is about 38 m (125 ft) higher than Mauna Loa, its more massive neighbor. Mauna Kea is unusually topographically prominent for its height: its prominence from sea level is fifteenth in the world among mountains, at 4,207.3 m (13,803 ft); its prominence from under the ocean is 9,330 m (30,610 ft), rivaled only by Mount Everest. This dry prominence is greater than Everest's height above sea level of 8,848.86 m (29,032 ft), and some authorities have labeled Mauna Kea the tallest mountain in the world, from its underwater base. Mauna Kea is ranked 8th by topographic isolation.
Kīlauea is an active shield volcano in the Hawaiian Islands. It is located along the southeastern shore of Hawaii Island. The volcano is between 210,000 and 280,000 years old and grew above sea level about 100,000 years ago. Since the islands were settled, it has been the most active of the five volcanoes that together form the island and among the most active volcanoes on Earth. The most recent eruption began in December 2024.
Hualālai is an active volcano on the island of Hawaiʻi in the Hawaiian Islands. It is the westernmost, third-youngest and the third-most active of the five volcanoes that form the island of Hawaiʻi, following Kīlauea and the much larger Mauna Loa. Its peak stands 8,271 feet (2,521 m) above sea level. Hualālai is estimated to have risen above sea level about 300,000 years ago. Despite maintaining a very low level of activity since its last eruption in 1801, and being unusually inactive for the last 2,000 years, Hualālai is still considered active, and is expected to erupt again sometime in the next 100 years. The relative unpreparedness of the residents in the area caused by the lull in activity would worsen an eruption's consequences.
The following is an alphabetical list of articles related to the U.S. state of Hawaii:
The Hawaiian Volcano Observatory (HVO) is an agency of the United States Geological Survey (USGS) and one of five volcano observatories operating under the USGS Volcano Hazards Program. Based in Hilo, Hawaii, the observatory monitors six Hawaiian volcanoes: Kīlauea, Mauna Loa, Kamaʻehuakanaloa, Hualālai, Mauna Kea, and Haleakalā, of which, Kīlauea and Mauna Loa are the most active. The observatory has a worldwide reputation as a leader in the study of active volcanism. Due to the relatively non-explosive nature of Kīlauea's volcanic eruptions for many years, scientists have generally been able to study ongoing eruptions in proximity without being in extreme danger.
Kohala is the oldest of five volcanoes that make up the island of Hawaii. Kohala is an estimated one million years old—so old that it experienced, and recorded, the reversal of Earth's magnetic field 780,000 years ago. It is believed to have breached sea level more than 500,000 years ago and to have last erupted 120,000 years ago. Kohala is 606 km2 (234 sq mi) in area and 14,000 km3 (3,400 cu mi) in volume, and thus constitutes just under 6% of the island of Hawaii.
Route 200, known locally as Saddle Road, traverses the width of the Island of Hawaiʻi, from downtown Hilo to its junction with Hawaii Route 190 near Waimea. The road was once considered one of the most dangerous paved roads in the state, with many one-lane bridges and areas of marginally maintained pavement. Most of the road has now been repaved, and major parts have new re-alignments to modern standards. The highway is mostly one-lane in each direction, but there are two lanes on the uphill portions. The highway reaches a maximum elevation of 6,632 feet (2,021 m) and is subject to fog and low visibility. Many rental car companies used to prohibit use of their cars on Saddle Road, but now allow use of the road. The highway experiences heavy use as it provides the shortest driving route from Hilo to Kailua-Kona and access to the slopes of Mauna Loa and the Mauna Kea Observatories.
The Hilina Slump, on the south flank of the Kīlauea Volcano on the southeast coast of the Big Island of Hawaiʻi, is the most notable of several landslides that ring each of the Hawaiian Islands. These landslides are the means by which material deposited at a volcano's vents are transferred downward and seaward, eventually spilling onto the seabed to broaden the island.
Hāmākua is a district on the northeast coast of Hawaiʻi's Big Island, administered by the County of Hawaiʻi in the state of Hawaiʻi. It is also the name given for the coastline in the region, the "Hāmākua Coast".
The Hawaiʻi Belt Road is a modern name for the Māmalahoa Highway and consists of Hawaiʻi state Routes 11, 19, and 190 that encircle the Island of Hawaiʻi. The southern section, between Hilo and Kailua-Kona is numbered as Route 11. The section between Hilo and Waimea is Route 19. Between Waimea and Kailua-Kona, the road is split in two: the original "mauka" route and a "makai" Route 19, completed in 1975, which serves as access to the Kona and Kohala Coast resorts. In the Hawaiian language, mauka means "towards the mountain" and makai means "towards the sea". These terms are commonly used in travel directions.
The 2006 Kīholo Bay earthquake occurred on October 15 at 07:07:49 local time with a magnitude of 6.7 and a maximum Mercalli intensity of VIII (Severe). The shock was centered 21 kilometers (13 mi) southwest of Puakō and 21 km (13 mi) north of Kailua-Kona, Hawaiʻi, just offshore of the Kona Airport, at a depth of 38.2 km (23.7 mi). It produced several aftershocks, including one that measured a magnitude of 6.1 seven minutes after the main shock. The Pacific Tsunami Warning Center measured a nondestructive tsunami of 4 in (100 mm) on the coast of the Big Island.
The Waiākea Mission Station was the first Christian mission on the eastern side of the Island of Hawaiʻi. Also known as the Hilo Station, the latest structure is now called Haili Church.
The 1868 Hawaiʻi earthquake was the largest recorded in the history of Hawaiʻi island, with an estimated magnitude of 7.9 Mfa and a maximum Mercalli intensity of X (Extreme). The earthquake occurred at 4 p.m. local time on April 2, 1868, and caused a landslide and tsunami that led to 77 deaths. The aftershock sequence for this event has continued up to the present day.
There are 75 golf courses in Hawaii.
The 2022 eruption of Mauna Loa was an episode of eruptive volcanic activity at Mauna Loa, the world's largest active volcano, located on Hawaiʻi island, Hawaiʻi. Mauna Loa began to erupt shortly before midnight HST on November 27, 2022, when lava flows emerged from fissure vents in Moku‘āweoweo. It marked the first eruption at the volcano in 38 years. The eruption ended on December 13, 2022, after more than two weeks.
Kenneth Hon, usually known professionally as Ken Hon, is a geologist and the 21st Scientist-in-Charge (SIC) of the Hawaiian Volcano Observatory (HVO), serving since 2021; succeeding Tina Neal (SIC) and David Phillips. Hon has often been a contact from the Observatory to the news media, and as such is often quoted as an authority figure in the field of Hawaiian volcanology.
