Most of this earthquake activity was deep, with most depth being at 16,0 km. This suggest that this earthquake swarm happened mostly due to magma movement at depth. There is nothing suggesting that eruption is imminent in this area. Depth of the ocean at this location is around 400 – 1000 meters, this means that any signs on the surface are going to be hard to detect or not detected at all.
