Using a method to better locate the source of weak tremors from regions with complex geological features, researchers from Kyushu University's International Institute for Carbon-Neutral Energy Research found that many tremors originate from the shear zone, an area of high fluid pressure within the pores of rocks, in the Nankai Trough, which is schematically shown here with the structures of the tectonic plates and fault lines. More accurately determined tremor sources and related geophysical properties that can be obtained from such information will aid the monitoring and modelling of large earthquakes along plate interfaces.
