What is the rictor scale of Etna?

The Richter scale measures the magnitude of earthquakes, not volcanic eruptions. However, Mount Etna, Italy's most active volcano, can produce seismic activity associated with its eruptions. The seismic magnitude of earthquakes related to volcanic activity at Etna can vary widely, but significant eruptions often generate tremors that might register between 2.0 and 4.0 on the Richter scale. It's important to monitor both volcanic and seismic activity closely for safety and research purposes.
