Moderate magnitude 4.1 quake hits 13 km northwest of Angra do Heroismo, Portugal in the evening

A magnitude 4.1 earthquake near Angra do Heroismo, Angra do Heroísmo Municipality, Azores, Portugal, was reported only 15 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a very shallow depth of 2.80 km beneath the epicenter in the evening on Thursday, November 6th, 2025, at 9:54 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the Portuguese Institute for Sea and Atmosphere (Instituto Português do Mar e da Atmosfera, IPMA) which listed the quake at magnitude 4.1 as well.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
