The 2018 Hokkaido Eastern Iburi Earthquake and Hidaka arc-arc collision system

The 2018 Mw 6.6 Hokkaido Eastern Iburi Earthquake generated strong ground shaking of JMA maximum intensity 7 and induced fatal landslides. The earthquake occurred beneath inland Hokkaido with an unusual deep hypocenter depth of 35km, possibly reflecting complex crustal and mantle structure of Hidaka arc-arc collision system. Connection of the earthquake with its nearby major active faults is still not very clear so far. Strong ground motion evaluation strategy of deep crustal earthquake is future challenge. This special issue will focus on multidisciplinary geoscientific researches by seismology, geodesy, electromagnetic and landslide study regarding this earthquake and associated phenomena.
