The Global Earthquake Model (GEM) is a public–private partnership initiated in 2006 by the Global Science Forum of the OECD to develop global, open-source risk assessment software and tools. With committed backing from academia, governments and industry, GEM contributes to achieving profound, lasting reductions in earthquake risk worldwide by ...
An earthquake warning system or earthquake alarm system is a system of accelerometers, seismometers, communication, computers, and alarms that is devised for rapidly notifying adjoining regions of a substantial earthquake once one begins. This is not the same as earthquake prediction, which is currently not capable of producing decisive event ...
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
Gutenberg–Richter law. Gutenberg–Richter law fitted to the aftershocks of the August 2016 Central Italy earthquake, during the Aug 22 - Sep 1 period. Notice that the linear fit fails at the upper and lower end, due to lack of registered events. Since the recording period is only 10 days, events of magnitude greater than 6 has not yet appeared.
6.0–6.9. 1,320. 5.0–5.9. 81,848. ← 2001–2010. 2021–2030 →. The following is a list of significant earthquakes for the period 2011–2020, listing earthquakes of magnitude 7 and above, or which caused fatalities. Deaths due to earthquake-caused tsunamis are included. For lists of earthquakes by country, which may include smaller and ...
The international project Global Earthquake Model (GEM) [31] has the aim of producing a world map of earthquake risk. As part of this gigantic effort, data sets will be improved, which are also needed for real time loss assessments. One of these is the data set on world housing properties.
This link shows the data availability for each organisation – note that this includes the ISC-GEM catalogue. Covers global earthquakes from 1901 onwards and US earthquakes from 1638. NCEI/WDS Global Significant Earthquake Database This online searchable database is intended to cover all significant global earthquakes from 2150 B.C. onwards.
5.0–5.9. 2,046. 4.0–4.9. 14,643. ← 2020. 2022 →. This is a list of earthquakes in 2021. 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.
