Abstract--Geologists have long sought an early warning system
for earthquakes since it is the best way to save lives and prevent
property damage. Currently, the seismic network in the Los
Angeles area is too sparse to provide any early warning. We
propose a distributed system using MEMS sensors attached to
volunteers' computers in homes and schools across the Los
Angeles area. This system will have the advantage of a faster
response time and a denser network than the existing system.
Index Terms--distributed computing, seismic network.
EARTHQUAKES are devastating natural disasters. They
are of particular concern to the people of the Los Angeles
area as the San Andreas Fault and other faults lie nearby.
ShakeOut, a scenario constructed by the United States Geo-
logical Survey, conservatively estimates that a 7.8 or higher
magnitude earthquake in this area would result in a death toll
