paragraph_text: The flag of Nigeria was designed in 1959 and first officially hoisted on 1 October 1960. The flag is a vertical 1: 2 triband of green, white, green. The two green stripes represent Nigeria's natural wealth, while the white band represents peace.

paragraph_text: The national flag of the Czech Republic (Czech: státní vlajka České republiky) is the same as the flag of former Czechoslovakia. Upon the dissolution of Czechoslovakia, the Czech Republic kept the Czechoslovak flag while Slovakia adopted its own flag. The first flag of Czechoslovakia was based on the flag of Bohemia and was white over red. This was almost identical to the flag of Poland (only the proportion was different), so a blue triangle was added at the hoist in 1920. The flag was banned by the Nazis in 1939, and a horizontal tricolor of white, red, and blue was enforced. The 1920 flag was restored in 1945.

paragraph_text: The flag of Ivory Coast (French: Drapeau de la Côte d'Ivoire) features three equal vertical bands of orange (hoist side), white, and green.

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.

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 national flag of Ireland (Irish: bratach na hÉireann) -- frequently referred to as the Irish tricolour (trídhathach na hÉireann) -- is the national flag and ensign of the Republic of Ireland. The flag itself is a vertical tricolour of green (at the hoist), white and orange. The proportions of the flag are 1: 2 (that is to say, flown horizontally, the flag is half as high as it is wide).

paragraph_text: The 2001 Kunlun earthquake also known as the 2001 Kokoxili earthquake, occurred on 14 November 2001 at 09:26 UTC (17:26 local time), with an epicenter near Kokoxili, close to the border between Qinghai and Xinjiang in a remote mountainous region. With a magnitude of 7.8 M it was the most powerful earthquake in China for 5 decades. No casualties were reported, presumably due to the very low population density and the lack of high-rise buildings. This earthquake was associated with the longest surface rupture ever recorded on land, ~450 km.

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: 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: 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 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: Due to its location in the Pacific Ring of Fire, Seattle is in a major earthquake zone. On February 28, 2001, the magnitude 6.8 Nisqually earthquake did significant architectural damage, especially in the Pioneer Square area (built on reclaimed land, as are the Industrial District and part of the city center), but caused only one fatality. Other strong quakes occurred on January 26, 1700 (estimated at 9 magnitude), December 14, 1872 (7.3 or 7.4), April 13, 1949 (7.1), and April 29, 1965 (6.5). The 1965 quake caused three deaths in Seattle directly, and one more by heart failure. Although the Seattle Fault passes just south of the city center, neither it nor the Cascadia subduction zone has caused an earthquake since the city's founding. The Cascadia subduction zone poses the threat of an earthquake of magnitude 9.0 or greater, capable of seriously damaging the city and collapsing many buildings, especially in zones built on fill.

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: The most widely used symbol is the flag of Greece, which features nine equal horizontal stripes of blue alternating with white representing the nine syllables of the Greek national motto Eleftheria i thanatos (freedom or death), which was the motto of the Greek War of Independence. The blue square in the upper hoist-side corner bears a white cross, which represents Greek Orthodoxy. The Greek flag is widely used by the Greek Cypriots, although Cyprus has officially adopted a neutral flag to ease ethnic tensions with the Turkish Cypriot minority – see flag of Cyprus).
