The Philippines is an archipelago that comprises 7,641 islands, and with a total land area of 300,000 square kilometers (115,831 sq mi), it is the world's fifth largest island country. The eleven largest islands contain 95% of the total land area. The largest of these islands is Luzon at about 105,000 square kilometers (40,541 sq mi). The next largest island is Mindanao at about 95,000 square kilometers (36,680 sq mi). The archipelago is around 800 kilometers (500 mi) from the Asian mainland and is located between Taiwan and Borneo.
Calabarzon, sometimes referred to as Southern Tagalog and designated as Region IV‑A, is an administrative region in the Philippines. The region comprises five provinces: Batangas, Cavite, Laguna, Quezon, and Rizal; and one highly urbanized city, Lucena. It is the most populous region in the Philippines, according to the Philippine Statistics Authority (PSA), having over 16.1 million inhabitants in 2020, and is also the country's second most densely populated after the National Capital Region. It is situated southeast of Metro Manila, and is bordered by Manila Bay and South China Sea to the west, Lamon Bay and the Bicol Region to the east, Tayabas Bay and the Sibuyan Sea to the south, and Central Luzon to the north. It is home to places like Mount Makiling near Los Baños, Laguna, and Taal Volcano in Batangas.
Mayon, also known as Mount Mayon and Mayon Volcano, is an active stratovolcano in the province of Albay in Bicol, Philippines. A popular tourist spot, it is renowned for its "perfect cone" because of its symmetric conical shape, and is regarded as sacred in Philippine mythology.
Mount Pinatubo is an active stratovolcano in the Zambales Mountains, located on the tripoint boundary of the Philippine provinces of Zambales, Tarlac and Pampanga, all in Central Luzon on the northern island of Luzon. Most people were unaware of its eruptive history before the pre-eruption volcanic activity in early 1991. Dense forests, which supported a population of several thousand indigenous Aetas, heavily eroded and obscured Pinatubo.
Taal Volcano is a large caldera filled by Taal Lake in the Philippines. Located in the province of Batangas about 50 kilometers (31 mi) south of Manila, the volcano is the second most active volcano in the country with 38 recorded historical eruptions, all of which were concentrated on Volcano Island, near the middle of Taal Lake. The caldera was formed by prehistoric eruptions between 140,000 and 5,380 BP.
Taal Lake, formerly known as Bombón Lake, is a fresh water caldera lake in the province of Batangas, on the island of Luzon in the Philippines. The lake fills Taal Volcano, a large volcanic caldera formed by very large eruptions between 500,000 and 100,000 years ago.
Tropical Storm Thelma, known in the Philippines as Tropical Storm Uring, was one of the deadliest tropical cyclones in Philippine history, killing at least 5,081 people. Forming out of a tropical disturbance on November 1, 1991, several hundred kilometers north-northeast of Palau, the depression that would become Thelma tracked generally westward. After turning southwestward in response to a cold front, the system intensified into a tropical storm on November 4 as it approached the Philippines. Hours before moving over the Visayas, Thelma attained its peak intensity with estimated ten-minute sustained winds of 75 km/h (45 mph) and a barometric pressure of 992 mbar. Despite moving over land, the system weakened only slightly, emerging over the South China Sea on November 6 while retaining gale-force winds. Thelma ultimately succumbed to wind shear and degraded to a tropical depression. On November 8, the depression made landfall in Southern Vietnam before dissipating hours later.
The Philippines is a typhoon-prone country, with approximately 20 typhoons entering its area of responsibility each year. Locally known generally as bagyo, typhoons regularly form in the Philippine Sea and less regularly, in the South China Sea, with the months of June to September being the most active, August being the month with the most activity. Each year, at least ten typhoons are expected to hit the island nation, with five expected to be destructive and powerful. In 2013, Time declared the country as the "most exposed country in the world to tropical storms".
Mount Bulusan, also known as Bulusan Volcano, is a stratovolcano on the island of Luzon in the Philippines. Located in the province of Sorsogon in the Bicol Region, it is 70 kilometres (43 mi) southeast of Mayon Volcano and approximately 390 kilometres (240 mi) southeast of Manila. Bulusan is one of the active volcanoes in the Philippines.
Typhoon Durian, known in the Philippines as Super Typhoon Reming, was a deadly tropical cyclone that wreaked havoc in the Philippines and later crossed the Malay Peninsula in late November 2006, causing massive loss of life when mudflows from the Mayon Volcano buried many villages.
The Philippine Institute of Volcanology and Seismology is a Philippine national institution dedicated to provide information on the activities of volcanoes, earthquakes, and tsunamis, as well as other specialized information and services primarily for the protection of life and property and in support of economic, productivity, and sustainable development. It is one of the service agencies of the Department of Science and Technology.
The National Disaster Risk Reduction and Management Council (NDRRMC), formerly known as the National Disaster Coordinating Council (NDCC) until August 2011, is a working group of various government, non-government, civil sector and private sector organizations of the Government of the Republic of the Philippines established on June 11, 1978 by Presidential Decree 1566. It is administered by the Office of Civil Defense (OCD) under the Department of National Defense (DND). The council is responsible for ensuring the protection and welfare of the people during disasters or emergencies. The NDRRMC plans and leads the guiding activities in the field of communication, warning signals, emergency, transportation, evacuation, rescue, engineering, health and rehabilitation, public education and auxiliary services such as fire fighting and the police in the country. The Council utilizes the UN Cluster Approach in disaster management. It is the country's focal for the ASEAN Agreement on Disaster Management and Emergency Response (AADMER) and many other related international commitments.
The 1991 eruption of Mount Pinatubo in the Philippines' Luzon Volcanic Arc was the second-largest volcanic eruption of the 20th century, behind only the 1912 eruption of Novarupta in Alaska. Eruptive activity began on April 2 as a series of phreatic explosions from a fissure that opened on the north side of Mount Pinatubo. Seismographs were set up and began monitoring the volcano for earthquakes. In late May, the number of seismic events under the volcano fluctuated from day-to-day. Beginning June 6, a swarm of progressively shallower earthquakes accompanied by inflationary tilt on the upper east flank of the mountain, culminated in the extrusion of a small lava dome.
Typhoon Amy was an intense and deadly tropical cyclone that struck areas of the central Philippines in December 1951. Impacting the archipelago during the 1951 eruption of Mount Hibok-Hibok, Amy exacerbated the effects of the volcano, greatly increasing the number of resulting deaths. The fifteenth named storm and fourteenth typhoon within the western Pacific Ocean that year, Amy developed from an area of low pressure near the Kwajalein Atoll on December 3. Tracking in a general westward direction, the storm quickly intensified to reach typhoon intensity the next day. However, the typhoon's asymmetricity resulted in a fluctuation of intensity over the following few days. Afterwards, Amy intensified to reach its peak intensity with maximum sustained winds of 220 km/h (140 mph) and a minimum barometric pressure of 950 mbar on December 8. Over the ensuing two days, Amy moved over several islands in the central Philippines before emerging in the South China Sea on December 11 as the equivalent of a minimal typhoon. Shortly after, the tropical cyclone executed a tight anticyclonic loop while oscillating in strength several times before eventually weakening and dissipating on December 17, just east of Vietnam.
The 1880 Southern Luzon earthquakes, were one of the most destructive tremors on record in the history of the country. The shocks continued, with greater or less interruption, from July 14–25, 1880; highlighted by three violent quakes measuring 7.0, Mw 7.6, and Mw 7.2 respectively. The sequence destroyed churches and other buildings, producing loss of life. Coinciding with the tectonic activity was an increase in volcanic activity in the Taal Volcano of southwestern Luzon.
Typhoon Haiyan, known in the Philippines as Super Typhoon Yolanda, was one of the most powerful tropical cyclones ever recorded. Upon making landfall, Haiyan devastated portions of Southeast Asia, particularly the Philippines. It is one of the deadliest Philippine typhoons on record, killing at least 6,300 people in that country alone. In terms of JTWC-estimated 1-minute sustained winds, Haiyan is tied with Meranti in 2016 for being the second strongest landfalling tropical cyclone on record, only behind Goni of 2020. As of January 2014, bodies were still being found. Haiyan was also the most intense tropical cyclone worldwide in 2013.
The 2017 Batangas earthquakes were an earthquake swarm that occurred from early April to mid-August 2017, affecting the province of Batangas in the Philippines and other nearby areas.
Taal Volcano in Batangas, Philippines began to erupt on January 12, 2020, when a phreatomagmatic eruption from its main crater spewed ashes over Calabarzon, Metro Manila, and some parts of Central Luzon and Ilocos Region, resulting in the suspension of school classes, work schedules, and flights in the area, as well as temporarily drying up Taal Main Crater Lake and destroying Vulcan Point, an Island surrounded by the lake. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) subsequently issued an Alert Level 4, indicating "that a hazardous explosive eruption is possible within hours to days." Volcanic activity continued into 2021, when smaller eruptions occurred in July 2021. On 26 March 2022, a short-lived phreatomagmatic eruption was recorded by PHIVOLCS raising the status from Alert level 2 to Alert level 3 as well as surrounding towns.
From September 20 to 26, 1867, the capital Manila of the Captaincy General of the Philippines experienced the full brunt of a storm, which was believed to be a typhoon. Dubbed as the 1867 Angela typhoon, the capital was submerged in floods from the storm. Many ships either disappeared in waters or were destroyed in the shores near Santa Lucia and Tondo, both towns near Manila Bay. The waves on the said bay were described as "mountainous" by some residents near the coast. The Spanish ship that departed from British Hong Kong named "Malaspina" sank near the Ilocos Region, killing an unknown number of passengers and crew with no survivors. The waters of the Abra River overflowed, killing over 1,800 individuals, mostly due to drowning. This would make the typhoon the fifth deadliest tropical cyclone ever to hit the present-day Philippines. No numerical estimate for the damage caused by the storm is available.
