Multi-Temporal Dinsar Techniques to Monitor the Activity of Aso And Sakurajima Volcanoes, Japan

The activity of Aso and Sakurajima volcanoes is monitored through interferometric analysis of SAR data, ALOS Palsar-2 and Sentinel-1, to obtain caldera displacements over the observed period, from 2014 to 2018 and to investigate deformations correlation with inflation and deflation cycles of magma p...

Description
Summary:The activity of Aso and Sakurajima volcanoes is monitored through interferometric analysis of SAR data, ALOS Palsar-2 and Sentinel-1, to obtain caldera displacements over the observed period, from 2014 to 2018 and to investigate deformations correlation with inflation and deflation cycles of magma plumbing system, eruptions and diking. The time series, calibrated through global navigation satellite System (GNSS) measurements, are used to identify the pre and post seismic effects of the Mw 7.0 Kumamoto earthquake, occurred in April 2016, to identify the effects on Aso volcano and the most dramatic events affecting the active Sakurajima area since 2015.
