<span class="mw-page-title-main">Aleutian Trench</span> An oceanic trench along the southern coastline of Alaska and the Aleutian islands

The Aleutian Trench is an oceanic trench along a convergent plate boundary which runs along the southern coastline of Alaska and the Aleutian islands. The trench extends for 3,400 kilometres (2,100 mi) from a triple junction in the west with the Ulakhan Fault and the northern end of the Kuril–Kamchatka Trench, to a junction with the northern end of the Queen Charlotte Fault system in the east. It is classified as a "marginal trench" in the east as it runs along the margin of the continent. The subduction along the trench gives rise to the Aleutian Arc, a volcanic island arc, where it runs through the open sea west of the Alaska Peninsula. As a convergent plate boundary, the trench forms part of the boundary between two tectonic plates. Here, the Pacific Plate is being subducted under the North American Plate at a dip angle of nearly 45°. The rate of closure is 7.5 centimetres (3 in) per year.

The 2001 southern Peru earthquake occurred at 20:33:15 UTC on June 23 with a moment magnitude of 8.4 and a maximum Mercalli intensity of XII (Extreme). The quake affected the Peruvian regions of Arequipa, Moquegua and Tacna. It was the most devastating earthquake in Peru since the catastrophic 1970 Ancash earthquake and globally the largest earthquake since the 1965 Rat Islands earthquake.

<span class="mw-page-title-main">2010 Chile earthquake</span> Magnitude 8.8 earthquake in Chile on 27 February 2010

The 2010 Chile earthquake and tsunami occurred off the coast of central Chile on Saturday, 27 February at 03:34:12 local time, having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes. It was felt strongly in six Chilean regions that together make up about 80 percent of the country's population. According to the United States Geological Survey (USGS) the cities experiencing the strongest shaking—VIII (Severe) on the Mercalli intensity scale (MM)—were Concepción, Arauco, and Coronel. According to Chile's Seismological Service, Concepción experienced the strongest shaking at MM IX (Violent). The earthquake was felt in the capital Santiago at MM VII or MM VIII. Tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza, and La Rioja. Tremors were felt as far north as the city of Ica in southern Peru. It is the largest earthquake to hit Chile since the 1960 Valdivia earthquake.

The 2021 Kermadec Islands earthquakes were a series of earthquakes with magnitudes of 8.1 and 7.4 that occurred at 19:28:31 UTC on 4 March 2021. The epicentres were located southeast of Raoul Island in the Kermadec Islands, part of the New Zealand outlying islands. The main magnitude 8.1 earthquake was preceded by a magnitude 7.4 foreshock and followed by a magnitude 6.1 aftershock. A separate, unrelated magnitude 7.3 earthquake occurred off the coast of the North Island of New Zealand, approximately 900 km to the south, several hours before the main quakes. More than a dozen aftershocks exceeded magnitude 6.

On 19 September 2022, a moment magnitude 7.6-7.7 earthquake struck between the Mexican states of Michoacán and Colima at 13:05:06 local time. The earthquake had a depth of 26.9 km (16.7 mi), resulting in a maximum intensity of VIII (Severe) on the Modified Mercalli intensity scale. The USGS reported the epicentre was 35 km (22 mi) southwest of the town of Aquila. Two people were killed and at least 35 others were injured across several states. A magnitude 6.8 aftershock struck on 22 September, causing three more deaths.
