List Of Earthquakes In 2020
This is a list of earthquakes in 2020. Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for other reasons. All dates are listed according to UTC time. Maximum intensities are indicated on the Modified Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. For the second consecutive year, activity was well below average, with only nine major quakes, it was also the first year since 2016 with no magnitude 8.0+ earthquakes. With just over 200 casualties reported, it is the least deadliest year in the 21st century for earthquakes, but almost all of them came from Turkey, struck by three deadly events. In the last days of the year, Croatia experienced one of its strongest earthquakes in its history, with casualties and structural damage. Compared to other years An increase in detected earthquake numbers does not necessarily represent an increase in earthquakes ''per s ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological SurveyThe "USGS Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Earthquakes In 2016
This is a list of earthquakes in 2016. Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for some other reason. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. Major events took place in Ecuador, Italy, Taiwan, Indonesia and New Zealand this year, while the strongest tremor was observed in Papua New Guinea. 2016 was also the first year since 2002 with no magnitude 8+ earthquakes. Compared to other years An increase in detected earthquake numbers does not necessarily represent an increase in earthquakes ''per se''. Population increase, habitation spread, and advances in earthquake detection technology all contribute to higher earthquake numbers being recorded over time. By death toll Listed are earthquakes with at least 10 dead. By magnitude Listed are earthquakes with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2021 Chignik Earthquake
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. This was the largest earthquake in the United States since the 1965 Rat Islands earthquake, and the 7th largest earthquake in US history. It was also the strongest earthquake globally since the 2015 Illapel earthquake, tying the 2017 Chiapas earthquake and 2018 Fiji earthquake. No casualties or serious damage were reported in the aftermath of the mainshock, as well as some of the strong aftershocks. In Perryville, the closest populated area to the quake, cracks appeared in drywalls and on the ground. Some homes were also ...
