Gravity changes before large earthquakes in China: 1998–2005

摘要: Although it is well known that coseismic gravity changes take place during an earthquake, previous research has not yielded convincing evidence demonstrating significant occur before large earthquakes. Furthermore, even if we suspect earthquakes, have yet to demonstrate how consistently observe these for useful earthquake forecast would bring benefits society. We analyzed ground survey data obtained in 1998, 2000, 2002, and 2005 at stations of the Crustal Movement Observation Network China (CMONOC) examined occurrence nine (Ms⩾6.8) earthquakes ruptured within or near mainland Taiwan from November 2001 August 2008. Results this analysis show occurred across a region each were detected by repeated surveys through CMONOC. gravity...
