There was a 6.3 magnitude earthquake north of Ascension Island on Wednesday.
It occurred at 3:08 pm local time at a depth of 10.0 km.
The earthquake was centered 767.5 km south of Georgetown, Ascension, Saint Helena.
Ascension is a geologically young formation, the tip of an undersea volcano which rose above the waves only a million years ago.
Although volcanic activity is mainly associated with the Mid-Atlantic Ridge plate boundary 80 km to the west, Ascension also displays some features which are commonly associated with hotspot volcanism.
