Two earthquakes occurring in Spain within hours of each other caused widespread damage, resulted in several fatalities and have left scientists scratching their heads as to how this happened in an area with an unremarkable seismic history.
MSNBC reports that 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.
The quakes, which occurred along a yet-unidentified fault, were shallow, rupturing just over a half-mile (1 kilometer) below ground, said John Bellini, a geophysicist with U.S. Geological Survey.
MSNBC reports that experts from Our Amazing Planet said the region of coastal Spain where the earthquakes struck does have a history of seismic activity, albeit a fairly tame one.
