Italy's national volcanology institute said the quake hit a few minutes before 9 p.m., when many people were having dinner. Casamicciola, on the northern part of the island, was the hardest-hit area.
There was a large discrepancy in the magnitude reported. Italy's national vulcanology agency initially reported the magnitude at 3.6, but later revised that to a 4.0 with a depth of 3 miles. The U.S. Geological Survey and the European-Mediterranean Seismological Center, however, gave it a 4.3 magnitude, with a depth of 6 miles.

A doctor at a local hospital told Sky TG24 that approximately 26 people are being treated for minor injuries as a result of the earthquake. One person was killed by falling masonry, Salerno said.
In 1883, Casamicciola was the epicenter of an earthquake that killed more than 2,000 people.
