FAQ
Frequently Asked Questions
Traditionally, a seismometer is the internal sensor that detects motion, while a seismograph is the complete instrument that includes both the sensor (seismometer) and a recording device. In modern usage, the terms are often used interchangeably.
No. A seismometer detects and measures ground motion as it happens. It is a monitoring tool, not a prediction tool. It records earthquakes but cannot forecast them.
They are installed in quiet locations (e.g., underground vaults, boreholes) to minimize noise from wind, traffic, and human activity. Networks are deployed in seismically active regions, near volcanoes, and globally for comprehensive monitoring.
Almost never. It is a highly specialized technical term. In everyday news reports about earthquakes, simpler terms like 'earthquake sensor' or 'measuring device' are more common, or the more familiar 'seismograph' might be used.
