In a status report on the seismovolcanic crisis on that Azorean island, published on its official website, CIVISA states that “to date, approximately 39,995 events of low magnitude and of tectonic origin have been recorded”.
According to CIVISA, the seismovolcanic activity on that island “continues to be above normal, extending, roughly, from Ponta dos Rosais to the Norte Pequeno – Silveira area”.
“Globally, the seismic activity of the last few weeks shows a slight decreasing trend, sometimes interrupted by short periods of higher frequency and/or energy released, with the hypocenters currently being located, in general, at depths greater than five kilometres”.
CIVISA indicates that “the existing data since the beginning of April do not show significant deformation in the epicentral zone”.
On the other hand, “the campaigns to measure gases and temperature in the soil that have been developed since the beginning of this crisis in the epicentral area have not resulted, to date, in the identification of anomalies resulting from seismovolcanic activity”.
On June 8, CIVISA lowered the alert level on the island of São Jorge from V4 (threat of eruption) to V3 (active system with no imminent eruption).
