The USGS has upgraded this event to a magnitude 6.3 event according to our seismic notification system. Earlier today the USGS reported a magnitude 6.0 earthquake along the Northern Mid-Atlantic ridge. The relatively powerful, and fairly shallow quake struck in mid-ocean approximately 325 miles southwest of the Portuguese Azores Islands. Given the remoteness of the event, no injuries or damage were reported. The reason for this report is that earthquakes of this magnitude are fairly atypical along the Mid-Atlantic ridge, as compared to in the Pacific. As for serious quakes, where human fatalities and property damage are involved, the last Mid-Atlantic quake of this sort occurred 30 years ago in the nearby Azores. Read more
