The 1980 Honduras earthquake struck just offshore Honduras on August 9 at 05:45 UTC. Two people were killed and many injured.
The earthquake hit at 05:45 UTC,around 11:47 PM local time. It caused the most damage at Puerto Barrios in Izabal Department, Guatemala, and Puerto Cortes, Honduras, and it killed two people and measured between 6.4 and 6.7 surface wave magnitude. The quake was felt throughout Honduras, Belize, and parts of Guatemala. Damage was recorded at the port town of Livingston and extended to northwestern Puerto Rico; this damage is poorly recorded.
The earthquake severed communications with rural hill and coastal villages in Honduras, and it frightened thousands of people into leaving their homes. Early reports listed only one fatality; a man from San Pedro Sula suffered a heart attack from the tremor's initial rupture. 100 mi (160 km) to the north, experienced the shaking but reported no damage. The earthquake did not extend to Tegucigalpa, Honduras' capital, or Guatemala's capital, Guatemala City.In Puerto Cortes, 75 homes, a hotel, a Texaco refinery, and a then-United Brands rail line all at least partially collapsed, the homes all fully. As a result, three people were injured by downed walls and ceilings. In Puerto Barrios, two homes collapsed. Belize City,
The earthquake's epicenter lay in the Gulf of Honduras, just offshore.
Honduras lies just off the triple-junction of the North American, Cocos, and Caribbean tectonic plates to the north. On the other sides it is surrounded by transform faults and trenches created by the movement of these plates. 6.5 cm (2.6 in) to 10 cm (3.9 in) annually. Within Honduras, there are at least three other major faults–La Ceiba, Guyape, and Aguan–apparently unrelated to plate movement.The most seismic activity occurs along the plate boundary between Caribbean and Cocos in a N–E trending Benioff zone, split into two sections, one with a shallow dip, the other with a far more steep decline. The plates are converging by subduction, Cocos under the Caribbean, at a rate of
Central America is a region in the southern tip of North America and is sometimes defined as a subregion of the Americas. This region is bordered by Mexico to the north, Colombia to the southeast, the Caribbean Sea to the east and the Pacific Ocean to the west and south. Central America consists of seven countries: El Salvador, Costa Rica, Belize, Guatemala, Honduras, Nicaragua and Panama. The combined population of Central America is estimated at 44.53 million (2016).
The North American Plate is a tectonic plate covering most of North America, Greenland, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores. With an area of 76 million km2 (29 million sq mi), it is the Earth's second largest tectonic plate, behind the Pacific Plate.
The New Madrid Seismic Zone, sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes in the southern and midwestern United States, stretching to the southwest from New Madrid, Missouri.
The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America.
The seismicity of the Sanriku coast identifies and describes the seismic activity of an area of Japan. Seismicity refers to the frequency, type and size of earthquakes experienced over a period of time. The Sanriku coast is a descriptive term referring to the coastal areas of the former provinces of Rikuō in Aomori, Rikuchū in Aomori, and Rikuzen in Miyagi.
The January 2001 El Salvador earthquake struck El Salvador on January 13, 2001 at 17:33:34 UTC. The 7.6 quake struck with the epicenter 60 miles (100 km) SW of San Miguel, El Salvador at a depth of 60 km. At least 944 people were killed, 5,565 injured, 108,261 houses destroyed — with another 169,692 houses damaged — and more than 150,000 buildings were damaged in El Salvador. About 585 of the deaths were caused by large landslides in Santa Tecla and Comasagua. As is often the case after earthquakes in El Salvador, landslides wreaked significant damage. Estimation of the number of slides is difficult because individual scarps conjoin. The total has been reported as high as 16,000, though it is unclear how this figure was arrived at. Damage and injuries occurred in every department of El Salvador, particularly the departments of La Libertad and Usulután. Eight people were killed in Guatemala. The tremor was felt from Mexico City to Colombia. An aftershock measuring 5.7 magnitude was felt on January 15, an event not widely reported outside the country until after the February quake, which initially was assessed by the USGS at 5.7 magnitude as well.
The 1976 Guatemala earthquake struck on February 4 at 03:01:43 local time with a moment magnitude of 7.5. The shock was centered on the Motagua Fault, about 160 km northeast of Guatemala City at a depth of 5 kilometers (3.1 mi) near the town of Los Amates in the department of Izabal.
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 1972 Nicaragua earthquake occurred at 12:29:44 a.m. local time on December 23 near Managua, the capital of Nicaragua. It had a moment magnitude of 6.3 and a maximum MSK intensity of IX (Destructive). The epicenter was 28 kilometers northeast of the city centre and a depth of about 10 kilometers. The earthquake caused widespread casualties among Managua's residents: 4,000–11,000 were killed, 20,000 were injured and over 300,000 were left homeless.
The 2009 Swan Islands earthquake occurred on May 28 at 02:24:45 AM local time with a moment magnitude of 7.3 and a maximum Mercalli intensity of VII. The epicenter was located in the Caribbean Sea, 64 kilometres (40 mi) northeast of the island of Roatán, 19 miles northeast of Port Royal, Isla de Bahias, 15 miles northwest of Isla Barbaretta, and 130 kilometres (81 mi) north-northeast of La Ceiba. Three aftershocks followed the earthquake within magnitude 4 range.
The 1222 Cyprus earthquake occurred at about 06:15 UTC on 11 May. It had an estimated magnitude of 7.0–7.5 and triggered a tsunami that was recorded in Libya and Alexandria. The strongest shaking was felt in Nicosia, Limassol and Paphos. Many people died, although there are no estimates for the total number of casualties.
The 1982 El Salvador earthquake occurred southeast of San Salvador on 19 June at 00:21 local time. This undersea earthquake struck offshore in the Pacific Ocean and had a surface wave magnitude of 7.2 and a maximum Mercalli intensity of VII. Occurring adjacent to a subduction zone at the Middle America Trench, this normal-slip shock left at least 16 and as many as 43 people dead, and many injured, and also inflicted $5 million in damage.
The 1932 Jalisco earthquakes began on June 3 at 10:36 UTC with a megathrust event that registered 8.2 on the moment magnitude scale. With a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale, at least 400 deaths were caused in Mexico and neighboring Guatemala. It was the first of a series of seismic events that affected parts of western Mexico during the month of June 1932, all reaching magnitude 7 or greater.
The 1954 Chlef earthquake struck Chlef Province in Algeria on September 9 at 02:04:43 local time. The shock measured 6.7 on the moment magnitude scale and had a maximum Mercalli intensity of XI (Extreme). It destroyed Chlef, then named Orléansville, leaving at least 1,243 people dead and 5,000 injured. Damage was estimated at $6 million. It was followed by multiple aftershocks. Algeria faces annual earthquakes and has undergone several changes to its earthquake building codes since its first earthquake engineering regulations from 1717.
The 1969 Sharm El Sheikh earthquake occurred on March 31 off the southern Sinai peninsula in northeastern Egypt. The epicenter was located near Shadwan island, southwest of the city of Sharm El Sheikh, at the confluence of the Red Sea and the Gulf of Suez. This normal-slip shock measured 6.6 on the moment magnitude scale, had a maximum reported intensity of VII on the Mercalli intensity scale, and was responsible for several deaths and injuries.
The 2017 Chiapas earthquake struck at 23:49 CDT on 7 September in the Gulf of Tehuantepec off the southern coast of Mexico, near state of Chiapas, approximately 87 kilometres (54 mi) southwest of Pijijiapan, with a Mercalli intensity of IX (Violent). The magnitude was estimated to be Mw8.2.
On 9 January 2018, at approximately 8:51 p.m. local time, a magnitude 7.5 earthquake struck in the Yucatán Basin of the Caribbean Sea, 44 kilometres (27 mi) east of Great Swan Island off the coast of Honduras. The earthquake was felt across Central America, and rattled windows in Tegucigalpa. The earthquake was also felt in the Cayman Islands.
The 2018 Oaxaca earthquake occurred on February 16, 2018 at 17:39 local time in the Sierra Madre del Sur in Oaxaca state in Southern Mexico. It had a magnitude of 7.2 on the moment magnitude scale and a maximum felt intensity of VII on the Mercalli intensity scale. The hypocenter was located at a depth of 24.6 km and approximately 37 km northeast of Pinotepa de Don Luis. There were only two reports of injuries from the earthquake, but later a military helicopter surveying the damage crashed and killed 14 people. There were also 15 people injured.
Starting on December 28, 2019, and progressing into 2020, the southwestern part of the island of Puerto Rico was struck by an earthquake swarm, including 11 that were of magnitude 5 or greater. The largest and most damaging of this sequence occurred on January 7 at 04:24 AST (08:24 UTC) and had a magnitude of 6.4 Mw and a maximum felt intensity of VII on the Modified Mercalli intensity scale. At least one person was killed and several others were injured.
