Inventors' Corner: U.S. Patent #7,693,663 - System and method for detection of earthquakes and tsunamis, and interface to warning systems

The patent describes a technique that uses data generated by vibration sensors (known as MEMS accelerometers) within computer hard disk drives to accurately and precisely conduct post-event analysis of seismic events, such as earthquakes. The invention also uses sensor data to assess and provide early warnings for tsunamis, which can follow earthquakes that occur at the ocean floor. Another
