This document discusses the uses of MEMS accelerometers in seismology. It begins with an introduction to earthquakes and seismic waves. It then discusses how MEMS accelerometers can be used to detect early earthquake information to provide earthquake early warning. Several studies are summarized that have used MEMS accelerometers for seismic monitoring, data acquisition, and detecting ground motion from earthquakes. The document concludes that while research using MEMS accelerometers in seismology has increased since 2003, more work is still needed compared to other fields, and it represents an important area for future research.
