Key:monitoring:seismic_activity

Seismometers are instruments that measure motion of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.

How to map

Add a node or draw its outline and add man_made=monitoring_station + monitoring:seismic_activity=yes.

Type of monitoring

There are different types of seismometers. Most are broadband seismometers but you can also monitor ground motion with e.g. GPS.

• seismic_activity:broadband=yes
• seismic_activity:gps=yes
