Looks as if the region still has an 8.1 or so capability. That one hardly scratched the surface.
There was a 7.6 here in 2009 and 7.7 in 2010
BANDA ACEH, Indonesia (Reuters) - Indonesia lifted a tsunami warning on Wednesday after a 7.3 magnitude earthquake struck off northern Sumatra, calming local residents who had earlier fled their houses to higher ground.
A witness at the beach in Aceh said the sea level had decreased following the quake, which also happened before a 2004 quake off Aceh created a tsunami that killed over 200,000 people around the Indian Ocean.
Alfan, a resident of Banda Aceh, said he joined about one hundred people gathered on a bridge in the town to watch the surface of a river to check if there was any change in its surface height, showing locals remain nervous about a big wave reaching shore.
The Mid-Cayman spreading centre is an ultraslow-spreading ridge in the Caribbean Sea. Its extreme depth and geographic isolation from other mid-ocean ridges offer insights into the effects of pressure on hydrothermal venting, and the biogeography of vent fauna. Here we report the discovery of two hydrothermal vent fields on the Mid-Cayman spreading centre. The Von Damm Vent Field is located on the upper slopes of an oceanic core complex at a depth of 2,300 m. High-temperature venting in this off-axis setting suggests that the global incidence of vent fields may be underestimated. At a depth of 4,960 m on the Mid-Cayman spreading centre axis, the Beebe Vent Field emits copper-enriched fluids and a buoyant plume that rises 1,100 m, consistent with >400 °C venting from the world's deepest known hydrothermal system. At both sites, a new morphospecies of alvinocaridid shrimp dominates faunal assemblages, which exhibit similarities to those of Mid-Atlantic vents.
