3.8 quake 26 km northwest of Faro, Portugal, Mar 17, 2023 3:35 am (GMT +0)
An earthquake of magnitude 3.8 occurred early morning on Friday, March 17th, 2023, at 3:35 am local time near Faro, Portugal, as reported by Spain's Instituto Geográfico Nacional (IGN).
According to preliminary data, the quake was located at a moderately shallow depth of 36 km. 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.
A second report was later issued by the Portuguese Institute for Sea and Atmosphere (Instituto Português do Mar e da Atmosfera, IPMA), which listed it as a magnitude 3.7 earthquake. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 3.7.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Boliqueime (pop. 4,500) located 3 km from the epicenter, Albufeira (pop. 15,900) 7 km away, Quarteira (pop. 18,800) 10 km away, Loule (pop. 23,100) 15 km away, Faro (pop. 41,400) 26 km away, Portimao (pop. 38,500) 31 km away, Olhao (pop. 29,200) 32 km away, Laranjeiro (pop. 20,500) 34 km away, and Lagos (pop. 18,800) 44 km away.
