The 1980 Honduras earthquake struck just offshore Honduras on August 9 at 05:45 UTC. Two people were killed and many injured.

Honduras republic in Central America

Honduras, officially the Republic of Honduras, is a country in Central America. It has at times been referred to as Spanish Honduras to differentiate it from British Honduras, which became modern-day Belize. The republic of Honduras is bordered to the west by Guatemala, to the southwest by El Salvador, to the southeast by Nicaragua, to the south by the Pacific Ocean at the Gulf of Fonseca, and to the north by the Gulf of Honduras, a large inlet of the Caribbean Sea.

Damage and casualties

The earthquake hit at 05:45 UTC, [2] around 11:47 PM local time. [3] It caused the most damage at Puerto Barrios [4] in Izabal Department, Guatemala, and Puerto Cortes, Honduras, [3] and it killed two and measured between 6.4 and 6.7 surface wave magnitude. [2] The quake was felt throughout Honduras, Belize, and parts of Guatemala. [3] Damage was recorded at the port town of Livingston and extended to northwestern Puerto Rico; this damage is poorly recorded. [4]

A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.

Puerto Barrios Municipality of Guatemala in Izabal

Puerto Barrios is a city in Guatemala, located within the Gulf of Honduras. The bay in which the harbour is located is called Bahia de Amatique. Puerto Barrios is the departmental seat of Izabal department and is the administrative seat of Puerto Barrios municipality.

Izabal Department Department in Izabal, Guatemala

Izabal is one of the 22 departments of Guatemala. Its coastal areas form part of the homeland of the Garifuna people.

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. [3] 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, 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. [3]

San Pedro Sula Place in Cortés, Honduras

San Pedro Sula is the capital of Cortés Department, Honduras. It is located in the northwest corner of the country in the Sula Valley, about 50 kilometres (31 mi) south of Puerto Cortés on the Caribbean Sea. With a census population of 719,063 in 2013, and 1,445,598 people living in its metropolitan area in 2010, it is the nation's primary industrial center and second largest city after the capital Tegucigalpa.

Myocardial infarction interruption of blood supply to a part of the heart

Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Often it occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat, or feeling tired. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain, or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock, or cardiac arrest.

Texaco, Inc. is an American oil subsidiary of Chevron Corporation. Its flagship product is its fuel "Texaco with Techron". It also owns the Havoline motor oil brand. Texaco was an independent company until its refining operations merged into Chevron Corporation in 2001, at which time most of its station franchises were divested to the Shell Oil Company. It began as the Texas Fuel Company, founded in 1901 in Beaumont, Texas, by Joseph S. Cullinan, Thomas J. Donoghue, Walter Benona Sharp, and Arnold Schlaet upon the discovery of oil at Spindletop.

Geology

The earthquake's epicenter lay in the Gulf of Honduras, just offshore. [3]

The epicenter, epicentre or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates.

Gulf of Honduras A large inlet of the Caribbean Sea, indenting the coasts of Belize, Guatemala, and Honduras.

The Gulf or Bay of Honduras is a large inlet of the Caribbean Sea, indenting the coasts of Belize, Guatemala, and Honduras. From north to south, it runs for approximately 200 km from Dangriga, Belize, to La Ceiba, Honduras.

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. [5] 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. [6] The plates are converging by subduction, Cocos under the Caribbean, at a rate of 6.5 cm (2.6 in) to 10 cm (3.9 in) annually. [7] Within Honduras, there are at least three other major faults–La Ceiba, Guyape, and Aguan–apparently unrelated to plate movement. [8]

North American Plate Large tectonic plate including most of North America, Greenland and a bit of Siberia

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. It extends eastward to the Mid-Atlantic Ridge and westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. The interior of the main continental landmass includes an extensive granitic core called a craton. Along most of the edges of this craton are fragments of crustal material called terranes, accreted to the craton by tectonic actions over a long span of time. It is thought that much of North America west of the Rocky Mountains is composed of such terranes.

Plate tectonics The scientific theory that describes the large-scale motions of Earths lithosphere

Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, since tectonic processes began on Earth between 3 and 3.5 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century. The geoscientific community accepted plate-tectonic theory after seafloor spreading was validated in the late 1950s and early 1960s.

Subduction A geological process at convergent tectonic plate boundaries where one plate moves under the other

Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to gravity into the mantle. Regions where this process occurs are known as subduction zones. Rates of subduction are typically in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries.

January 2001 El Salvador earthquake January-February 2001 earthquakes in El Salvador

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.

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.

2011 Oklahoma earthquake second-strongest Oklahoma earthquake on record, centered near Prague

The 2011 Oklahoma earthquake was a 5.7 magnitude intraplate earthquake which occurred near Prague, Oklahoma on November 5 at 10:53 p.m. CDT in the U.S. state of Oklahoma. The epicenter of the earthquake was in the vicinity of several active wastewater injection wells. According to the United States Geological Survey (USGS), it was the most powerful earthquake ever recorded in Oklahoma; this record was surpassed by the 2016 Oklahoma earthquake. The previous record was a 5.5 magnitude earthquake that struck near the town of El Reno in 1952. The quake's epicenter was approximately 44 miles (71 km) east-northeast of Oklahoma City, near the town of Sparks and was felt in the neighboring states of Texas, Arkansas, Kansas and Missouri and even as far away as Tennessee and Wisconsin. The quake followed several minor quakes earlier in the day, including a 4.7 magnitude foreshock. The quake had a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale in the area closest to the epicenter. Numerous aftershocks were detected after the main quake, with a few registering at 4.0 magnitude.

1932 Jalisco earthquakes

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.
