Will Arabia Be So Lucky Next Time?
A swarm of at least 30,000 tremors that struck Harrat Lunayyir, an ancient lava field in western Arabia, between April and June 2009 was a ‘failed eruption,’ US and Arabian geologists say.

Based on the ground deformation satellite data, depth and signature of the shockwaves, the researchers have concluded that the seismic activity was related to a ‘failed volcanic eruption.’ They say magma has now moved very close to the surface, increasing the probability of an eruption.
The Arabian peninsula’s western side comprises lava fields [harrat] measuring up to 200,000 square kilometers, which were formed over the past 30 million years, after Arabia split from Africa.
