Lists of earthquakes Lists of earthquakes

Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from events too weak to be detectable except by sensitive instrumentation, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history. Below, earthquakes are listed by period, region or country, year, magnitude, cost, fatalities and number of scientific studies.

Haida Gwaii An archipelago in British Columbia, Canada

Haida Gwaii is an archipelago located between 55–125 km (34–78 mi) off the northern Pacific coast of Canada. The islands are separated from the mainland to the east by the shallow Hecate Strait. Queen Charlotte Sound lies to the south, with Vancouver Island beyond. To the north, the disputed Dixon Entrance separates Haida Gwaii from the Alexander Archipelago in the U.S. state of Alaska.

British Columbia Coast Coastal region of British Columbia, Canada

The British Columbia Coast, popularly referred to as the BC Coast or simply the Coast, is a geographic region of the Canadian province of British Columbia. As the entire western continental coastline of Canada along the Pacific Ocean is in B.C., it is synonymous with being the West Coast of Canada.

Moresby Island

Moresby Island is a large island that forms part of the Haida Gwaii archipelago in British Columbia, Canada, located at 52°45′00″N131°50′00″W.

Queen Charlotte Fault

The Queen Charlotte Fault is an active transform fault that marks the boundary of the North American plate and the Pacific plate. It is Canada's right-lateral strike-slip equivalent to the San Andreas Fault to the south in California. The Queen Charlotte Fault forms a triple junction south with the Cascadia subduction zone and the Explorer Ridge. The Queen Charlotte Fault (QCF) forms a transpressional plate boundary, and is as active as other major transform fault systems in terms of slip rates and seismogenic potential. It sustains the highest known deformation rates among continental or continent-ocean transform systems globally, accommodating greater than 50mm/yr dextral offset. The entire approximately 900 km offshore length has ruptured in seven greater than magnitude 7 events during the last century, making the cumulative historical seismic moment release higher than any other modern transform plate boundary system.

The 1949 Queen Charlotte Islands earthquake struck Haida Gwaii and the Pacific Northwest coast at 8:01 p.m. PDT on August 21. The shock had a surface wave magnitude of 8.1 and a maximum Mercalli Intensity of VIII (Severe).

United States Geological Survey Scientific agency of the United States government

The United States Geological Survey, abbreviated USGS and formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

The 2012 Haida Gwaii earthquake occurred just after 8:04 p.m. PDT on October 27. The shock had a moment magnitude of 7.8 and a maximum Mercalli Intensity of V (Moderate). The earthquake's epicentre was on Moresby Island of the Haida Gwaii archipelago. This was the second largest Canadian earthquake ever recorded by a seismometer, after the 1949 Queen Charlotte Islands earthquake, about 135 kilometres (84 mi) away. One person died due to a car crash related to the tsunami in Oahu, Hawaii.

2013 Craig, Alaska earthquake Earthquake in Alaska and British Columbia

The 2013 Craig, Alaska earthquake struck on January 5th, 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 damages.

2021 Chignik earthquake 7th largest earthquake in the US

An earthquake occurred off the coast of the Alaska Peninsula on July 28, 2021, at 10:15 p.m. local time. The large megathrust earthquake had a moment magnitude of 8.2 according to the United States Geological Survey (USGS). A tsunami warning was issued by the National Oceanic and Atmospheric Administration (NOAA) but later cancelled. The mainshock was followed by a number of aftershocks, including three that were of magnitude 5.9, 6.1 and 6.9 respectively.
