Geophysically Imaging Beneath Mt. Paektu Volcano, DPRK (August 2013 – August 2015)

Abstract

SEIS-UK provided a loan of 6 broadband seismic systems (4 x CMGESP, 2 x CMG40T) for a period of 24 months, for deployment in a linear network that extended ~60 km from eastwards from Mt. Paektu in the Democratic People’s Republic of Korea (DPRK, the formal name for North Korea). The seismic systems recorded continuously at 50Hz with relatively minor data losses due to equipment problems, but with some data loss from human error and weather/animals. All data are archived on the SEISUK system and will be sent to IRIS (Incorporated Research Institutions for Seismology) and made publicly available in September 2018. To date, we have used the data to produce images of crustal structure beneath the DPRK side of the volcano. These show evidence for significant melt stored in the crust. All these results have been presented at international conferences and have been and are currently being written up for leading international journals.
