Ground swells near Mount Hakone

May 17, 2015

Japanese experts say they have confirmed ground swelling in the no-entry zone on Mount Hakone since an increase of volcanic activity last month.

Officials at the Geospatial Information Authority released findings from data collected by a ground observation satellite.

The experts compared measurements taken on Friday with those from April 17th, before intensified volcanic activity. They found an upthrust of up to 12 centimeters. The swelling is in the southwestern part of a 100-meter radius in the Owakudani valley.

The experts say that ground around the center of the no-go area has also swollen by up to 10 centimeters.

Officials have prohibited anyone from going into an area around the valley after an increase in the number of minor earthquakes on the volcano. - NHK World News
