Endevco chose Sensors Expo to highlight its new Model 87 low-noise compact seismic accelerometer. Designed specifically for measuring ultra-low-level seismic events and low-frequency vibration on ...

Trimble has introduced an integrated GNSS reference receiver, broadband seismic recorder and a force-balance triaxial accelerometer for infrastructure and precise scientific applications. The Trimble ...

The system works on laptops which have a built in Sudden Motion Sensors, but desktops can also be part of the network by adding inexpensive (USD$49) USB accelerometers. In fact, desktops suit the ...

The accelerometer chip in iPhones can accurately detect seismic movement, and perhaps even provide a few crucial seconds of warning before the most energetic waves from an earthquake arrive.

Teachers can then use these accelerometers to show students simple seismic effects. For example, by bouncing a heavy ball on the ground at increasing distance from the accelerometer, they can show ...

They hope that the sensitivity will improve as cell phone accelerometers get better. There are some obvious issues that would get in the way of using such a phone-based seismic network ...
