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.

In Santa Barbara (pop. 1,300) located 4 km from the epicenter, Sao Bartolomeu (pop. 2,000) 7 km away, Biscoitos (pop. 1,400) 9 km away, and Sao Mateus (pop. 3,800) 10 km away, the quake should have been felt as light shaking.
