Seismic activity reported in Juneau

    Juneau, Alaska (KINY) - The Alaska Earthquake Center said the activity is not caused by earthquakes but ice quakes.

    The center said 27 different incidents were recorded between July 15-17 east of Juneau on the Juneau Icefield.

    Seismologist Natalia Ruppert said most of the activity is near Mount Ogden on the Wright Glacier.

    "The earthquakes are associated with glacial activity.  They generate seismic waves but they are not detecting underground motions.  These motions are on the surface like glacial ice or the glacier itself."

    The quakes registered between 1.6 and 3.2 on the Richter scale. They were recorded approximately 35 miles east of Douglas.

    Ruppert said there hasn't been this level of activity there since 2013.

    She said precipitation and water buildup could be causing the problem from melting.
