Of the “many hundreds” of earth tremors, only 28 were felt by the population of the central zone of the island of São Miguel
The seismic situation that is affecting the area since Sunday in the central zone of the island of São Miguel, in the Azores, between the Serra de Água de Pau and Lagoa do Congro, “should last a few days, but it is expected that its intensity will decrease in the next hours and over the next few days”, according to Miguel Miranda, President of the Portuguese Institute for the Sea and Atmosphere (IPMA)” He stressed that “The fact that this seismic crisis occurs in a very limited area of the island “points in this direction”..
Yesterday afternoon, the CIVISA, the Volcanological and Seismological Observatory of the University of the Azores, which constantly monitors the monitoring of the geological risks in the Azores, already had “a slight decrease in seismic activity”, as indicated to DN Teresa Ferreira, a research. The situation will continue, however, to be monitored and both experts warn that the population should remain alert to the indications of the regional civil protection service. This, as well as the regional government, who are monitoring the situation at all times (see text on the side).
Seismic activity has intensified in the central part of the island of São Miguel by 23.47 on Sunday (local time) and since then “many hundreds of micro-species have already been recorded” in the area – their final accounts were still at the end of the day, to be completed by CIVISA researchers.
“Only 28 of these earthquakes were felt by the resident population between Água de Pau and Povoação, on the south coast, and between Rabo de Peixe and Fenais da Ajuda, on the north coast,” said Teresa Ferreira. “The most intense of all recorded earthquakes hit 3.1 on the Richter scale and occurred at 06.18 [yesterday], and the last one that was felt still occurred in the morning at 11.25,” the researcher said.
