Ground shaking during devastating flood offers new insights

Scientists were able to record a sudden outburst of a glacial lake with seismometers deployed the year before in the wake of the catastrophic Ghorka earthquake in April 2015. The authors of a new study argue that such major flood events have a greater impact on erosion rates than the annual monsoon rainfalls. The reason is that the water masses mobilize large boulders and coarse sediment which usually protect the riverbed.
