image: The damage in Mashiki after Saturday's (April 16, 2016) earthquake was unexpected because the town is about 2 km (1.6 miles) away from Futagawa Fault. Hiroshima University Associate Professors Hideaki Goto and Yasuhiro Kumahara followed the trail of disrupted earth branching off from Futagawa Fault all the way into the center of Mashiki. This trail of surface ruptures may trace a newly identified branch of Futagawa Fault. Professor Emeritus Takashi Nakata led a separate team to map surface ruptures along the known portion of Futagawa Fault, first identified over 30 years ago. view more
