Researchers from Japan and Indonesia have pioneered a new method for more accurately estimating the source of weak ground vibrations in areas where one tectonic plate is sliding under another in the sea. Applying the approach to Japan s Nankai Trough, the researchers were able to estimate previously unknown properties in the region, demonstrating the method s promise to help probe properties needed for better monitoring and understanding larger earthquakes along this and other plate interfaces.
