Microearthquake

A microearthquake is a small-scale earthquake that typically has a magnitude of less than 3.0 on the moment magnitude scale (Mw) or the Richter scale. These earthquakes are usually not strong enough to be felt by people but can be recorded by seismographs. Microearthquakes can occur anywhere in the world, often due to tectonic plate movements, volcanic activity, or human activities such as mining or geothermal energy production.
