At 05:44:46 UTC on October 13, the U.S. Geological Survey recorded a magnitude 6.7 earthquake beneath the central Mid-Atlantic Ridge. The reviewed hypocenter was placed at 0.169 degrees north, 19.860 degrees west, at a depth of 10 kilometers.
The location is remote ocean, far from the dense human sensor network made of buildings, phones and witnesses. USGS assigned a green PAGER alert and, when this dispatch was filed, listed no felt reports. Those observations support a narrow claim about reported consequences so far. They do not make the earthquake small.
Magnitude measures the event at its source; intensity describes effects at particular places. A large offshore rupture can therefore enter the global catalog quickly while producing little immediate public testimony. The instruments and the impact record answer different questions.
The event page may be revised as analysts incorporate more waveforms. This filing preserves the reviewed parameters and impact indicators available at publication, and does not infer damage, tsunami effects or tectonic consequences that the cited record does not report.
