An earthquake measuring 3.7 on the Richter scale was felt on Tuesday on the island of Faial in the Azores, the Azores Center for Seismic Volcanic Information and Observation (CIVISA) said.

“According to the information currently available, the earthquake was felt at maximum intensity III (Modified Mercalli Scale) in the parishes of Capelo, Castelo Branco, Feteira and Praia do Norte (Municipality of Horta, Faial Island),” the report said. .
On the Richter scale, earthquakes are classified by magnitude into micro (less than 2.0), very small (2.0-2.9), small (3.0-3.9), weak (4.0-4.9), moderate (5.0-5.9). ), strong (6.0-6.9), large (7.0-7.9), important (8.0-8.9), exceptional (9.0-9.9) and extreme (when higher 10).
