paragraph_text: The island of Guam is 30 miles (50 km) long and 4 to 12 miles (6 to 19 km) wide, 3⁄4 the size of Singapore. The island experiences occasional earthquakes due to its location on the western edge of the Pacific Plate and near the Philippine Sea Plate. In recent years, earthquakes with epicenters near Guam have had magnitudes ranging from 5.0 to 8.7. Unlike the Anatahan volcano in the Northern Mariana Islands, Guam is not volcanically active. However, due to its proximity to Anatahan, vog (i.e. volcanic smog) does occasionally affect Guam.

paragraph_text: The 2007 Solomon Islands earthquake took place on 2 April 2007, near the provincial capital of Gizo on Ghizo Island, in Solomon Islands. Its magnitude was estimated at 8.1 on the scale, and 7.8 on the scale. The tsunami that followed the earthquake killed 52 people. According to the USGS, the earthquake was recorded around 7:39:56 a.m. local time (UTC+11). The focus was 10 km (6 mi) deep and 40 km (25 mi) South South-East of Gizo township on New Georgia Islands in Western Province. There were numerous aftershocks, the largest of which had a magnitude of 6.2.

paragraph_text: 12 January: the magnitude 7.0 2010 Haiti earthquake which occurred on 12 at 16: 53, local time. The earthquake killed between 46,000 and 316,000 people. Its epicentre was at approximately 25 km from Port - au - Prince, the capital. A dozen secondary shocks of magnitudes ranging from 5.0 to 5.9 were registered during the hours which followed. 20 January: A second earthquake of magnitude 6.1 occurred on 20 January 2010 at 06: 03 local time. Its epicentre was at approximately 59 km west of Port - au - Prince, and at least 10 km beneath the surface. 20 October: A cholera epidemic hit outside of Port - au - Prince, killing at least 3,597 and sickening over 340,000. 5 November: Hurricane Tomas hits and kills at least 10 Haitiens causing damage and worsening the cholera epidemic.

paragraph_text: The 2003 Boumerdès earthquake occurred on May 21 at in northern Algeria. The shock had a moment magnitude of 6.8 and a maximum Mercalli intensity of X ("Extreme"). The epicentre of the earthquake was located near the town of Thénia in Boumerdès Province, approximately 60 km east of the capital Algiers. The quake was the strongest to hit Algeria in more than twenty years – since 1980, when a magnitude 7.1 earthquake resulted in at least 2,633 deaths.

paragraph_text: In glaciated areas where the glacier moves faster than one km per year, glacial earthquakes occur. These are large scale temblors that have seismic magnitudes as high as 6.1. The number of glacial earthquakes in Greenland peaks every year in July, August and September and is increasing over time. In a study using data from January 1993 through October 2005, more events were detected every year since 2002, and twice as many events were recorded in 2005 as there were in any other year. This increase in the numbers of glacial earthquakes in Greenland may be a response to global warming.

paragraph_text: On Thursday, September 19, 1985, at 7:19 am local time, Mexico City was struck by an earthquake of magnitude 8.1 on the Richter scale. Although this earthquake was not as deadly or destructive as many similar events in Asia and other parts of Latin America, it proved to be a disaster politically for the one-party government. The government was paralyzed by its own bureaucracy and corruption, forcing ordinary citizens to create and direct their own rescue efforts and to reconstruct much of the housing that was lost as well.

paragraph_text: On March 27, 1964, the massive Good Friday earthquake killed 133 people and destroyed several villages and portions of large coastal communities, mainly by the resultant tsunamis and landslides. It was the second-most-powerful earthquake in the recorded history of the world, with a moment magnitude of 9.2. It was over one thousand times more powerful than the 1989 San Francisco earthquake. The time of day (5:36 pm), time of year and location of the epicenter were all cited as factors in potentially sparing thousands of lives, particularly in Anchorage.

paragraph_text: The June 2011 Christchurch earthquake was a shallow magnitude 6.0 earthquake that occurred on 13 June 2011 at 14:20 NZST (02:20 UTC). It was centred at a depth of , about 5 km (3 mi) south-east of Christchurch, which had previously been devastated by a magnitude 6.2 M earthquake in February 2011. The June quake was preceded by a magnitude 5.9 M tremor that struck the region at a slightly deeper 8.9 km (5.5 mi). The United States Geological Survey reported a magnitude of 6.0 M at a depth of about 9 km (5.6 mi).

paragraph_text: The 2011 Yunnan earthquake was a 5.4 magnitude earthquake that occurred on 10 March 2011 at 12:58 CST, with its epicenter in Yingjiang County, Yunnan, People's Republic of China, near the Burmese border. A total of 26 people died and 313 were injured with 133 in serious condition. China's Xinhua reports that up to seven aftershocks, measuring up to a magnitude of 4.7, followed the initial quake, which caused a total of 127,000 people to be evacuated to nearby shelters. It joined over 1,000 other minor tremors that affected the region in the two preceding months. Following damage surveys, officials reported that 1,039 buildings were destroyed and 4,994 more were seriously damaged. The earthquake occurred one day before a much larger earthquake struck Japan that also formed a tsunami.

paragraph_text: The 2011 earthquake off the Pacific coast of Tōhoku (東北地方太平洋沖地震, Tōhoku - chihō Taiheiyō Oki Jishin) was a magnitude 9.0 -- 9.1 (M) undersea megathrust earthquake off the coast of Japan that occurred at 14: 46 JST (05: 46 UTC) on Friday 11 March 2011, with the epicentre approximately 70 kilometres (43 mi) east of the Oshika Peninsula of Tōhoku and the hypocenter at an underwater depth of approximately 29 km (18 mi). The earthquake is often referred to in Japan as the Great East Japan Earthquake (東日本大震災, Higashi nihon daishinsai) and is also known as the 2011 Tōhoku earthquake, and the 3.11 earthquake. It was the most powerful earthquake ever recorded in Japan, and the fourth most powerful earthquake in the world since modern record - keeping began in 1900. The earthquake triggered powerful tsunami waves that reached heights of up to 40.5 metres (133 ft) in Miyako in Tōhoku's Iwate Prefecture, and which, in the Sendai area, traveled up to 10 km (6 mi) inland. The earthquake moved Honshu (the main island of Japan) 2.4 m (8 ft) east, shifted the Earth on its axis by estimates of between 10 cm (4 in) and 25 cm (10 in), increased earth's rotational speed by 1.8 μs per day, and generated infrasound waves detected in perturbations of the low - orbiting GOCE satellite. Initially, the earthquake caused sinking of part of Honshu's Pacific coast by up to roughly a meter, but after about three years, the coast rose back and kept on rising to exceed the original height of the coast.

paragraph_text: The 1983 Biga earthquake hit northwestern Turkey on 5 July 1983. Responsible for five deaths and approximately twenty-six casualties throughout Biga and Erdek and damage in Istanbul, the earthquake measured 6.1 on the surface wave magnitude scale. It shook places as far away as eastern Greece. The United States Geological Survey listed the earthquake among the "Significant Earthquakes of the World" for 1983.

paragraph_text: New Delhi lies on several fault lines and thus experiences frequent earthquakes, most of them of mild intensity. There has, however, been a spike in the number of earthquakes in the last six years, most notable being a 5.4 magnitude earthquake in 2015 with its epicentre in Nepal, a 4.7-magnitude earthquake on 25 November 2007, a 4.2-magnitude earthquake on 7 September 2011, a 5.2-magnitude earthquake on 5 March 2012, and a swarm of twelve earthquakes, including four of magnitudes 2.5, 2.8, 3.1, and 3.3, on 12 November 2013.

paragraph_text: Official figures (as of July 21, 2008 12:00 CST) stated that 69,197 were confirmed dead, including 68,636 in Sichuan province, and 374,176 injured, with 18,222 listed as missing. The earthquake left about 4.8 million people homeless, though the number could be as high as 11 million. Approximately 15 million people lived in the affected area. It was the deadliest earthquake to hit China since the 1976 Tangshan earthquake, which killed at least 240,000 people, and the strongest in the country since the 1950 Chayu earthquake, which registered at 8.5 on the Richter magnitude scale. It is the 21st deadliest earthquake of all time. On November 6, 2008, the central government announced that it would spend 1 trillion RMB (about US $146.5 billion) over the next three years to rebuild areas ravaged by the earthquake, as part of the Chinese economic stimulus program.
