Seismic activity at Furnas volcano, on the island of São Miguel, in the Azores, recorded an increase in the last few hours. The situation led to a decision being made by the authorities, although the article does not specify which one.
The seismic events detected so far were of low magnitude, not representing, for now, a significant threat. The increase in seismic activity in the area was, however, considered sufficient to justify preventive measures.
