The An earthquake with a magnitude of 3.7 on the Richter scale was recorded today on the island of Faial, revealed the Seismic Information and Surveillance Center of the Azores (CIVISA).
According to the Richter scale, earthquakes are classified according to their magnitude as micro (less than 2.0), very small (2.0-2.9), small (3.0-3.9), slight (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 greater than 10).
The Modified Mercalli scale measures the “degrees of intensity and their description”.
With an intensity III, considered weak, the quake is “felt inside the house” and “the pending objects swing”, feeling a “vibration similar to that caused by the passage of heavy vehicles”, describes the Institute of the Sea and Atmosphere (IPMA) on its website.
