Spain earthquake: The quakes that struck Spain Wednesday were seismically mild, but they occurred close to the surface, geologists say.
The two earthquakes in Spain Wedesday (May 11) that killed nine people and caused significant damage struck an area with a tame seismic history. Their shallow point of origin contributed to the deaths and destruction.
An estimated 10,000 people have been told not to return to their homes.
The quakes ripped masonry and bricks from buildings, according to the Associated Press.
The first quake, a magnitude 4.5, struck at 5:05 p.m. local time, and was followed by a stronger, 5.3 magnitude earthquake almost two hours later, at 6:47 p.m. [7 Ways the Earth Changes in the Blink of an Eye]
"Earthquakes close to the surface cause the most of damage no matter what type of fault it is," Bellini told OurAmazingPlanet.
Footage of the quake broadcast on a Spanish news channel shows a church tower falling to rubble and bricks crashing onto cars on the street below.
The earthquakes appear to have wrought outsize destruction for their relatively low magnitude, a fact that could be due to a prevalence of older buildings in the region.
