[...] Japan Meteorological Agency (JMA) and had (corrected to 7.4 M7.3, after) normal fault type earthquake was initially tensile force occurs at a place called the outer rise of the trench further offshore work. However, Tokyodai Earthquake Research Institute, where the group was to analyze in detail the waveform of the earthquake, it is divided into two earthquake. It is seen thrust type earthquake occurs compressive force is working in the first internal plate of the sea, and normal fault type earthquakes occurred after 10-20 seconds followed.

Yep the Japan quake was indeed complicated, may have been deep compressional outer rise quake followed (+20sec) by shallow tensional one
