Fig. 5From: Detection of crustal deformation prior to the 2014 Mt. Ontake eruption by the stacking methodShort, medium, long, and dike stacked data for the a 2007 and b 2014 eruptions. The number of earthquakes detected daily is also shown. Upward changes represent extension by inflation of the pressure source. Red arrows indicate the timing of each eruption, and the vertical black bars show when the first changes in the source were detectedBack to article page
