According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
In an earthquake, damage to buildings and infrastructure is related more closely to ground motion, of which PGA is a measure, rather than the magnitude of the earthquake itself. For moderate earthquakes, PGA is a reasonably good determinant of damage; in severe earthquakes, damage is more often correlated with peak ground velocity. [3]
The 2008 film Journey to the Center of the Earth has the protagonists Professor Trevor Anderson, his nephew Sean Anderson, and a volcanologist's daughter ending up at the Center of the Earth after traversing a mine system. Unlike the book, the "Center of the Earth" is thousands of miles beneath the Earth's surface and is an air pocket ...
Our understanding and preparedness have come a long way since Northridge's magnitude 6.7 earthquake in 1994. We're still learning from that destructive temblor. The 1994 Northridge quake was a shock.
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.
