UPDATE 2:58 UTC : We fear that a totally new subduction zone is becoming unstable with the risk of many aftershocks
UPDATE 2:55 UTC : The epicenter lies along the same subduction zone responsible for the massive March 11 earthquake.
UPDATE 2:52 UTC : The epicenter of the aftershocks is coming a lot closer to Hokkaido
UPDATE 2:50 UTC : Maximum intensity for both aftershocks = 3 (on a scale from 0 to 7).
2 very strong aftershocks on top of the subduction zone of northern Honshu but luckily at a safe distance out of the coast. The location of the epicenter is surprisingly more to the north of 90% of the other aftershocks.
Epicenter is at least 150 km from the coastline and this NOT dangerous.
There was NEVER a tsunami danger.
This are the data of both aftershocks :
