Abstract We investigate temporal variation in shear-wave splitting parameters of local earthquakes around Nias Island, the northern part of Sumatran forearc. We analyse a total of 79 high-quality splitting measurements recorded at a GEOFON seismic station (GSI) from 2009-2015. We observe that there...
