The 1997 Punitaqui earthquake occurred at 01:03 UTC on October 15. It had an estimated magnitude of 7.1 . This earthquake was one of the most destructive in the epicentral area compared to other events of subduction of the same size. The extensive damage to structures was the result of an amplification effect on the ground and the poor quality of building materials, this reflects the potential for damage incurred in an intraplate earthquake with vertical fault and how it can be much greater than what which can cause one of interplate of similar magnitude, and caused severe damage in Chilean cities of La Serena, Vicuña, Ovalle, Illapel and Punitaqui.
The 1998 Bahía de Caráquez earthquake occurred on August 4 at 13:59 local time with a magnitude 7.2.

In Bahía de Caráquez, electricity, telephone, and water services disrupted, and many buildings were damaged. It was felt strongly in Guayaquil and Quito and could be felt in much of Ecuador and in Cali, Colombia. An Mw 5.4 foreshock occurred 1 hour and 24 minutes before the main shock and hence alerted many people. The Nazca Plate is subducting beneath the South American Plate near the Ecuadorian coast. This earthquake was a shallow thrust earthquake in this subduction zone.

The Valparaíso earthquake of April 2017 was a strong earthquake that shook the cities of Valparaíso and Santiago on Monday, April 24, 2017, at 18:38 local time. Its epicenter was located off the coast of the Valparaíso Region and had a magnitude of 6.9 Mw. On the scale of Mercalli, the earthquake reached an intensity of VII.
On January 1, 1996, at 4:05 p.m. Central Indonesia Time, an earthquake with an epicenter in the Makassar Strait struck north of Minahasa on the island of Sulawesi, Indonesia. The earthquake measured 7.9 on the moment magnitude scale and was centered off Tolitoli Regency in Central Sulawesi, or 25 km from the Tonggolobibi village. A tsunami of 2–4 m (6.6–13.1 ft) was triggered by this earthquake as a result. At least 350 buildings were badly damaged, nine people died and 63 people were injured.
The 2013 Craig, Alaska earthquake struck on January 5, at 12:58 am (UTC–7) near the city of Craig and Hydaburg, on Prince of Wales Island. The Mw 7.5 earthquake came nearly three months after an Mw 7.8 quake struck Haida Gwaii on October 28, in 2012. The quake prompted a regional tsunami warning to British Columbia and Alaska, but it was later cancelled. Due to the remote location of the quake, there were no reports of casualties or damage.
The 1940 Lima earthquake occurred on May 24 at 11:35 a.m. PST with a magnitude of Mw 8.2 on the moment magnitude scale. Shaking from this powerful earthquake was felt throughout the country, and in Ecuador and Chile. An estimated 179 to 300 Peruvians lost their lives while 3,500 left injured by the earthquake. The earthquake was centered near the coastal cities of Huacho and Huaura, about 150 km (93 mi) north of the Peruvian capital, Lima. A tsunami of up to two meters was generated without major damage.

A total of 106 schools, 119 houses, and 14 other infrastructures were damaged by the earthquake.
The 1950 Calama earthquake occurred near the Argentina–Chile border with an epicenter near Calama, Chile in the Atacama Desert on December 9. The event had a hypocenter depth of 113.9 km, beneath the Caichinque volcanic complex.
