Improvement on Xi’an Digital Seismic Telemetry Network

Abstract

A scientific analysis on the geographical environments and regional geological tectonic features of some notable earthquakes over the world revealed the root cause of tectonic earthquakes—that is, a tectonic earthquake is generally caused by underground water erosion instead of inter-continental plate collision. According to this new law, it’s easy to explain many past great earthquakes around the world, and also easy to predict some future possible earthquake foci by observing landforms, that is, great earthquakes occur easily in coastal areas, or areas retaining large amounts of water, but not in areas lacking water. So these research results are important to economically protecting against earthquakes and reducing disasters. Especially, according to this new explanation, many digital seismograph networks in the world can be improved. Through on-the-spot investigation or observing topographic maps, one can find that Xi’an urban area and some of its surrounding areas lack underground water, and the possibility of devastating earthquakes occurring in these areas is vey low. Hence the observation on these areas can be lessened. But some areas such as Weihe down-faulted basin near Huaxian and Huayin is seismic risk area, the observation on these areas should be enhanced.
