earthquake detection

Earthquake detection is the use of instruments and systems to identify seismic activity.

Seismographs measure ground movement, while modern networks can provide early warnings seconds before shaking arrives at populated areas.

Detection systems monitor fault lines continuously: The earthquake detection network registered a 4.2 magnitude tremor.

Animals have long been observed behaving strangely before earthquakes, though scientific earthquake detection relies on precise measurement rather than such anecdotal signs.
