Just a Note: Blot Echo from previous post was indeed answered,[M5.6 – 178km W of Kamiiso, Japan 2017-03-27 22:31:21 UTC at a depth of 10.0 km], just outside of projected time frame and to more to the North rather to the NE, and .4 of a magnitude shy of a hit. https://drive.google.com/file/d/0B83EkoitOiKQZnY3QV85am1VOU0/view?usp=sharing
The main purpose for the update: For the Japan region, 300-500 km seems to be the asthenospheric alert zone for Blot Echoes, while 200-300 km large follow up earthquakes do not result.
