Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from weak events detectable only by seismometers, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history. Below, earthquakes are listed by period, region or country, year, magnitude, cost, fatalities, and number of scientific studies.
The 2005 Hindu Kush earthquake hit northeastern Afghanistan with a magnitude of 6.5 on December 12 at 21:47 (UTC). According to the United States Geological Survey, the maximum Mercalli intensity was V (Moderate) at Chitral. Five people were killed in the Hindu Kush region and landslides blocked several roads near Bagh, Kashmir. The earthquake occurred some 65 miles away from Faizabad, a city in the Hindu Kush mountains, but it could be felt in many neighboring areas. It could even be felt about 200 miles away in Islamabad, Pakistan. The quake was strong enough to trigger panic among survivors of October's devastating earthquake, who came out from their makeshift shelters in freezing temperatures. Although magnitude–6 earthquakes typically cause severe damage, this quake caused relatively little due to the fact that it occurred deep underground.
The March 2007 Sumatra earthquakes occurred near the northern end of Lake Singkarak in Sumatra, Indonesia, on March 6. The first shock in this earthquake doublet struck with a maximum Mercalli intensity of VIII (Severe) and the second shock that arrived two hours later had a maximum Mercalli intensity of VI (Strong).
The September 2007 Sumatra earthquakes were a series of megathrust earthquakes that struck the Sunda Trench off the coast of Sumatra, Indonesia, with three of magnitude 7 or greater. A series of tsunami bulletins was issued for the area. The most powerful of the series had a magnitude of 8.4, which makes it in the top 20 of the largest earthquakes ever recorded on a seismograph.
The 1946 Vancouver Island earthquake struck Vancouver Island on the coast of British Columbia, Canada, on June 23 at 10:15 a.m. with a magnitude estimated at 7.0 and 7.5 . The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur at tectonic plate boundaries, the 1946 Vancouver Island earthquake was a crustal event. Shaking was felt from Portland, Oregon, to Prince Rupert, British Columbia. This is one of the most damaging earthquakes in the history of British Columbia, but damage was restricted because there were no heavily populated areas near the epicentre, where severe shaking occurred.
The Xingtai earthquake was a sequence of major earthquakes that took place between March 8 and March 29, 1966, in the area administered by the prefecture-level city of Xingtai in southern Hebei province, People's Republic of China.
The 2009 West Papua earthquakes occurred on January 4 local time in Indonesia's Tambrauw Regency in Southwest Papua. The very large earthquake doublet comprised a 7.6 initial shock that had a maximum Mercalli intensity of VI (Strong) and a second event measuring Mw 7.4 and a maximum Mercalli intensity of VII. The events took place less than three hours apart to the east-northeast of Sorong on the Bird's Head Peninsula and left at least four people dead and dozens injured.
The 2010 Mindanao earthquakes occurred in the southern Philippines in the Moro Gulf. This was a complex sequence of events including three main events of magnitude 7.3 or greater on the 23rd of July, and two significant aftershocks of magnitude 6.6 on the 24th and 29th. All of these were deep focus earthquakes, at depths from 565 km (351 mi) to 634 km (394 mi). This resulted in minimal, but very widespread shaking at the surface, with a maximum intensity of IV on the PEIS scale; consequently there were no reports of casualties or damage.
Events from the year 1957 in Iran.
On May 4, 2018, an earthquake with a magnitude of 6.9 struck Hawaii island in the Hawaii archipelago at around 12:33 p.m. local time. The earthquake's epicenter was near the south flank of Kīlauea, which has been the site of seismic and volcanic activity since late April of that year. According to the United States Geological Survey the quake was related to the new lava outbreaks at the volcano, and it resulted in the Hilina Slump moving about two feet. It was the largest earthquake to affect Hawaii since the 1975 earthquake, which affected the same region, killing two people and injuring another 28.
On 4 May 2000 at 12:21 WITA, Banggai Islands Regency was hit by an earthquake of magnitude 7.5 , followed by a tsunami. The Banggai Islands, an archipelago located at the far eastern end of Central Sulawesi, Indonesia, was the worst affected by the earthquake. Eighty percent of Banggai's buildings were destroyed. Damage also occurred on Peleng. The earthquake triggered a local tsunami of up to 6 m in height that caused significant damage east of Luwuk on the mainland and on Peleng.
In 1954, the state of Nevada was struck by a series of earthquakes that began with three magnitude 6.0+ events in July and August that preceded the Mw 7.1–7.3 mainshock and M 6.9 aftershock, both on December 12. All five earthquakes are among the largest in the state, and the largest since the Cedar Mountain earthquake of 1932 and Pleasant Valley event in 1915. The earthquake was felt throughout much of the western United States.
The western coast of West Sulawesi was struck by a major earthquake on 23 February 1969 at 00:36 UTC. It had a magnitude of 7.0 and a maximum felt intensity of VIII on the Modified Mercalli intensity scale. It triggered a major tsunami that caused significant damage along the coast of the Makassar Strait. At least 64 people were killed, with possibly a further 600 deaths caused by the tsunami.
The 2003 Dayao earthquake occurred on July 21, at 23:16:33 CST. The epicenter of the moment magnitude 5.9 earthquake was in Dayao County in the mountainous area of central Yunnan, China. At least 19 people were killed, 644 were injured, and 8,406 families became homeless. The quake also caused $75 million USD in damage.
On 29 November, at 14:10 UTC, a magnitude 7.7 earthquake struck off the southern coast of Taliabu Island Regency in North Maluku, Indonesia. At least 41 people were killed on the nearby islands and a tsunami was triggered. Several hundred homes, buildings and offices were damaged or destroyed.
The 1979 Saint Elias earthquake affected Alaska at 12:27 AKST on 28 February. The thrust-faulting 7.5 earthquake had an epicenter in the Granite Mountains. Though the maximum recorded Modified Mercalli intensity was VII, damage was minimal and there were no casualties due to the remoteness of the faulting. Damage also extended across the border in parts of Yukon, Canada.
The 1991 Guatemala earthquake occurred on September 18 at 3:48 a.m. local time. The epicenter was 60 miles southwest of Guatemala City. The shock was assigned a magnitude of 5.3 on the Richter scale, later assigned with a magnitude of 6.2. It caused 25 deaths, over 200 injuries and left 1,000 people without homes.
