Abstract

Micro Elector Mechanical Systems (MEMS) sensors enable a wide range of different applications in many fields: among others, in the last decade the use of MEMS accelerometers for seismology-related applications has grown exponentially. In this paper, we do a comprehensive review of MEMS accelerometers: Operating Principle, technical specifications, types, performance, Comparison with Geophone. We introduce the applications within seismology and earth sciences related disciplines. We introduce how to use MEMS accelerometer and geophone to build a low Coast earthquake monitoring unit. Moreover, we will discuss the performance of MEMS accelerometer, geophone by conducting a practical experiment to measure one of the explosions that occur near the city of Helwan, Cairo, Egypt.
