Small earthquake in the Volcanic Zone

A small earthquake occurred in the scenic volcanic zone of the Reykjanes Peninsula on the morning of 9 March 2014. The local magnitude was 2.8 and resulted in very small ground motions at the closest recording station of the Icelandic Strong-motion Network, which is owned and operated by the Earthquake Engineering Research Centre.

The plot below shows as summary of the recording of ground accelerations in the basement of a 2-story structure, shown at the bottom of the photo above (courtesy of Mats Wibe Lund). While the ground motions were only slight, and therefore the earthquake action, the earthquake serves as a reminder that the volcanic zones are also earthquake zones and strong-earthquakes have taken place there, resulting in damage to man-made structures.
