ShakeMap is a product of the U.S. Geological Survey (USGS) to map the shaking of earthquakes.According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes.
Map showing the amount of advance warning time that might be available from ShakeAlert for several plausible future earthquake scenarios. [1]Initially the system has been developed to monitor and alert the West Coast of the United States, an area with significant seismic risk due to the San Andreas fault zone and the Cascadia subduction zone.
Note that 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.
This is a list of earthquakes in 2005.Only earthquakes of magnitude 6 or above are included, unless they resulted in significant damage or casualties, or were notable for some other reason.
This is a list of earthquakes in 2018.Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for other reasons.
