Two new earthquakes were felt this Monday morning on the island of São Miguel, in the Azores, both with a magnitude greater than 2.0 on the Richter scale.

According to a statement from the Azores Regional Civil Protection and Fire Service, which mentions the Azores Seismovolcanic Surveillance and Information Center (CIVISA), one of the events was registered at 9:31 am local time (10:31 am in Lisbon) and had a magnitude of 2.5 on the scale from Richter and epicenter about three kilometers south / southwest of Povoação.

The earthquake was felt with maximum intensity III / IV on the Modified Mercalli scale in Povoação, in Ribeira Quente and Nossa Senhora dos Remédios, in the municipality of Povoação. The event was also felt with intensity III in Furnas, in the same municipality.

Subsequently, at 9h54 local time (10:54 am in Lisbon), a new earthquake was recorded with magnitude 2.4 (Richter) and epicenter about four kilometers south-south-southwest of Povoação. The earthquake was felt with maximum intensity III / IV (Modified Mercalli scale) in Povoação and Nossa Senhora dos Remédios. According to CIVISA, the event was also felt with intensities III in Ribeira Quente and Faial da Terra and intensity II / III in Furnas.

Early on Monday morning, a first earthquake measuring 4.8 on the Richter scale with an epicenter about 19 kilometers east / northeast of Formigas had been felt in São Miguel, an event recorded at 7:07 am local (8:07 am in Lisbon).

Speaking to Lusa, the president of the Azores Seismovolcanic Surveillance and Information Center (CIVISA), Rui Marques, explained that these two new earthquakes felt in São Miguel “have nothing to do with the first in terms of location”, because "Are in very different places".

However, its temporal proximity and its northwest-southeast alignment, coinciding with one of the main tectonic alignments of São Miguel, may indicate that these earthquakes are related ”, he added, speaking to Lusa.

The official stressed that these are "two seismogenic zones that are tectonically active and that frequently present activity".

The first earthquake was felt “in almost the whole island” of São Miguel and the last two “circumscribed to the municipality of Povoação”, also referred the president of CIVISA.

Contacted by Lusa, the Civil Protection of the Azores said there was no record of any occurrences related to the earthquakes.
