Rationale: The way the wind is folding into that area looks like its being drawn into the fault zone and the wind speeds above the fault on other readings seems high. The OLR(credit PSD) that has been slow moving across China towards Japan could meet up in the fault zone and cause the quake. Although the OLR data doesn’t seem such a high reading they easily morph overnight. Small possibility of a higher quake into the 7+ range. In addition to increased speeds the reading on the 10hPa level or the stratosphere seems to have a dead zone of air in the same area.
