Depth is determined by assuming several point sources. We chose the solution whose variance reduction becomes the maximum. Point source interval is 3km between 5km and 120km, 5km between 120km and 200km, and 10km between 200km and 400km. You will find the figure showing the result at the bottom. Right hand side is the moment tensor solution.
Moment tensor is shown in equal area lower hemisphere projection.
White area is dilatational region at the source and black is compressional region. Either of two boundaries shows the fault surface. If you click the station code, you will see original waveforms. The unit of horizontal axis is second and vertical axis is count. Among these waveforms, we used at most three station whose hypocentral distance is between 50km and 400km and whose data quality is good.
