Effects

The 2003 Colima earthquake resulted in 29 deaths and 300 injuries. Additionally, approximately 10,000 were left homeless as the earthquake destroyed 2,005 homes and seriously damaged 6,615. Most of the deaths and damage occurred in Villa de Álvarez, a city which borders the northern part of the city of Colima. Extensive damage (rating VIII) occurred in the city of Colima and in Tecomán. Some deaths and damage occurred in the states of Jalisco and Michoacán and a few buildings were damaged as far away as Guanajuato and Morelos. The quake was felt strongly (rating VI) in parts of Mexico City. It was also felt in most of Mexico and in the United States in Corpus Christi, Texas, Dallas, Texas and El Paso, Texas. Occupants of high-rise buildings in Houston, Texas also reported feeling its effects. Landslides closed a segment of the Colima-Guadalajara Highway and the port of Manzanillo. Power and telephone outages occurred in Mexico City. A local tsunami of about 1 m (peak-to-trough) was recorded at Manzanillo. A seiche was observed on Lake Pontchartrain in the US state of Louisiana, and sediment was stirred up in several Louisiana wells. [2]

Tectonic summary

This shallow earthquake occurred in a seismically active zone near the coast of central Mexico. The earthquake occurred near the juncture of three tectonic plates: the North American Plate to the northeast, the Rivera Plate to the northwest, and the Cocos Plate to the south. Both the Rivera Plate and the Cocos Plate are being subsumed beneath the North American Plate. The slower subducting Rivera Plate is moving northwest at about 2 cm per year relative to the North American Plate and the faster Cocos plate is moving in a similar direction at a rate of about 4.5 cm per year.

Several significant earthquakes have occurred near the recent event. In 1932, a magnitude 8.4 thrust earthquake struck about 100 km to the north-northwest. On 9 October 1995, a magnitude 7.6 earthquake struck about 50 km to the northwest killing at least 49 people and leaving 1,000 homeless. The most deadly earthquake in the region occurred about 170 km to the south-east on 19 September 1985. This magnitude 8.0 earthquake killed at least 9,500 people, injured about 30,000, and left 100,000 people homeless. [4]

It was felt with III (Weak) to IV (Light) around San Jose, Costa Rica. Shops in the center of Puerto Armuelles suffered from loss such as fallen merchandise and broken window glass. This earthquake occurred along the Panama Fracture Zone.

<span class="mw-page-title-main">1920 Xalapa earthquake</span> Earthquake in Mexico

The 1920 Xalapa earthquake was the deadliest in Mexico's history prior to 1985—killing at least 648 people. It occurred on January 3 at 22:25 local time, during a period of political unrest in the country. Mudflows and landslides triggered by the shock destroyed buildings in rural towns across the states of Veracruz and Puebla, causing most of the deaths. The earthquake was attributed to a shallow fault in the Trans-Mexican Volcanic Belt. It measured moment magnitude 6.3–6.4 and had a hypocenter depth of <15 km (9.3 mi). The Mexican government took immediate action in the aftermath—providing assistance and establishing communication services. Severely damaged towns including Xalapa were rebuilt, while others had to be abandoned. Help to survivors also came from civil society groups, civilians, and the Catholic Church. The earthquake's aftershocks were studied by scientists to determine its seismological characteristics.

On April 13, 1923 at 15:31 UTC, an earthquake occurred off the northern coast of the Kamchatka Peninsula in the USSR, present-day Russia. The earthquake had a surface-wave magnitude (Ms ) of 6.8–7.3 and an estimated moment magnitude (Mw ) of 7.0–8.2. This event came just two months after a slightly larger earthquake with an epicenter struck south of the April event. Both earthquakes were tsunamigenic although the latter generated wave heights far exceeding that of the one in February. After two foreshocks of "moderate force", the main event caused considerable damage. Most of the 36 casualties were the result of the tsunami inundation rather than the earthquake.

The 1912 Acambay earthquake struck the State of Mexico on 19 November at 07:55 local time. It had a moment magnitude of 6.7–6.9 Mw  and an epicenter near the town of Acambay, 80 km (50 mi) northwest of Mexico City. Up to 161 people died and there was severe destruction. It is regarded as one of the most important earthquakes in Mexico's seismological history, having been widely studied.
