The 2022 Guatemala earthquake occurred on the early morning of February 16, 2022 in the southern regions of Guatemala. The quake measured a moment magnitude of 6.2 and reached a peak intensity of VI (Strong) on the Modified Mercalli Intensity scale. [2] Damage was widespread but light in and around the capital, Guatemala City, resulting mostly in cracked walls and rockslides. [3] [4]

Tectonic setting

The coastline of Guatemala lies above the convergent boundary where the Cocos Plate is being subducted beneath the North American Plate or Caribbean Plate along the line of the Middle America Trench. Earthquakes associated with this plate boundary include the 7.4 Mw  2012 Guatemala earthquake that ruptured the plate interface, and the 6.9 Mw  2014 Mexico–Guatemala earthquake caused by faulting within the subducting Cocos Plate. The northern part of the country hosts the Motagua Fault and Chixoy-Polochic Fault, accommodating left-lateral strike-slip movement on the transform boundary between the North American and Caribbean plates. The Motagua Fault was the source of many destructive earthquakes in Northern Guatemala, most notably the 1976 Guatemala earthquake with a magnitude of 7.5 Mw . [5] [6]

The earthquake had a preliminary magnitude of 6.8 according to local seismological agencies but was later revised to 6.2 in the moment magnitude scale by the United States Geological Survey (USGS). [2] The quake, at a depth of 83.6 km (52 mi), reached a peak intensity of VI (Strong) on the Modified Mercalli intensity scale.

MMI LocationsPopulation exposure
MMI VI (Strong) Nueva Concepción 441,000
MMI V (Moderate) Quetzaltenango, Guatemala City, Escuintla 4.62 million
MMI IV (Light) Chimaltenango, Santa Ana 13.4 million

Damage and casualties

The earthquake caused damage in seven departments of the country. It damaged or destroyed 39 houses and buildings in and around the capital, Guatemala City, and caused multiple landslides blocking roads near the mountains. Three people suffered fatal heart attacks, one each in Mixco, Quetzaltenango, and Baja Verapaz, while two people, including a minor, suffered injuries. [1] [8] [9] [10]

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 Motagua Fault is a major, active left lateral-moving transform fault which cuts across Guatemala. It forms part of the tectonic boundary between the North American Plate and the Caribbean Plate. It is considered the onshore continuation of the Swan Islands Transform Fault and Cayman trench, which run under the Caribbean Sea. Its western end appears not to continue further than its surface trace, where it is covered by Cenozoic volcanics.

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 1971 Bingöl earthquake was a Mw  6.6 earthquake that occurred at 18:44:02 local time on 22 May. It had a surface-wave magnitude of 6.9 and a maximum intensity of VIII (Severe) on the Mercalli intensity scale, killing 755–1,000 people.

The 1999 Oaxaca earthquake occurred on September 30 at 11:31 local time in Oaxaca, Mexico, 60 km NNW of Puerto Ángel. The epicenter was located near San Agustin Loxicha. It had a magnitude of Mw 7.4.

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 7.3 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 2011 Guerrero earthquake struck with a moment magnitude of 5.7 in southern Mexico at 08:24 local time on 5 May. It was positioned west of Ometepec, Guerrero, with a focal depth of 24 km (14.9 mi), and was lightly felt in many adjacent areas.

The 2012 Guerrero–Oaxaca earthquake struck southern Mexico with a moment magnitude of 7.4 at 12:02 local time on Tuesday, 20 March. Its epicenter was near Ometepec, in the border between the states of Guerrero and Oaxaca. With a shallow focus of 20 km, the earthquake caused strong shaking over a large area along the Oaxaca–Guerrero border and the adjacent Pacific coastline. Significant tremors were felt in areas up to several hundred kilometers away, including Mexico City and also in Guatemala. Two people were killed and over 30,000 houses were damaged or destroyed.

The 2012 Costa Rica earthquake occurred at 08:42 local time on September 5. The epicenter of the 7.6 Mw earthquake was in the Nicoya Peninsula, 11 kilometers east-southeast of Nicoya. A tsunami warning was issued shortly afterwards, but later cancelled. Two people are known to have died, one from a heart attack and another, a construction worker, crushed by a collapsing wall. It was the second strongest earthquake recorded in Costa Rica's history, following the 1991 Limon earthquake.
