ABSTRACT:
A seismograph system includes a seismometer, a positioning unit, a transmitter, a remote processing device. The seismometer includes a micro electromechanical system (MEMS) accelerometer and a MEMS gyroscope. The seismometer, the positioning unit, and the transmitter being located at a detecting site. The MEMS accelerometer and the MEMS gyroscope are respectively configured for measuring an acceleration and an angular velocity of the movement of the earth at the detecting site. The positioning unit is configured for providing a location at the detecting site. The transmitter is configured for transmitting the measured acceleration, the measured angular velocity, and the provided location to the remote processing device. The remote processing device is positioned at a remote site and configured for analyzing recording the measured acceleration, the measured angular velocity, and the provided location.
