with soo many large-ish quakes, the chance of a large aftershock at a much shallower depth could have the potential of increased risk of tsunami
this is what i am wondering.
Volcanic alert level raised for Mt. Hakone
Japan's Meteorological Agency has raised the volcanic alert level for Mount Hakone, which is in a hot spring resort town outside Tokyo.
The agency boosted its alert level to two on a scale of five early Sunday. It is warning of the possibility of an eruption and large volcanic rocks falling around the crater in the Owakudani valley.
It's the first time in four years that the alert level for the volcano was set at two.
The agency made the decision after the number of volcanic earthquakes at Mount Hakone increased to 45 the day before. As of 9 a.m. on Sunday, 21 tremors have been observed.
The agency says small, shallow-focus quakes have been increasing in some areas near Mount Hakone since mid-March.
Officials of the town of Hakone have decided to restrict travel near the crater and have set up fences to block access.
A vendor near Owakudani said he's concerned because customers had just started to return after the eruption four years ago. He added that he is praying for the volcano to calm down and can only wait for it to do so.
The operator of Hakone Ropeway has suspended the service. A temporary bus service is running instead.
A man on a trip with his wife said he experienced shaking while eating. He said he is disappointed because he came to see the view of Mount Fuji from Owakudani.
A tourist from Australia said he was looking forward to taking the ropeway, but will try to find another way to enjoy nature in the area.

nothing out of the ordinary though a little deeper than normal.
by triangulating this quake with the angle of common movement of direction
this places a leaning toward naze island as the next place to require movement.
on the assumption that deep movement of this nature continues adding the angle of twist on the plate to be slightly higher than i anticipated by previous movement.
imagine a rope that is being shaken up and down or side to side to makes waves
you can touch the rope in different parts and make changes which effect how the end of the rope & certain waves crest or sharpen/change a little , but the over all movement remains the same basic process and all parts are subject to randomized and collective forces at all times based on minute un chartable differences like the strength and flexibility at certain points of the rope, air density, etc etc...
this is not a prediction
this is me attempting to anticipate a concept of motion
it never stays the same, it is like tumbling balls in a barrel constantly spinning
you cant accurately predict a specific ball in a specific place
that is scientifically impossibly

appears to be quite deep and in the middle of the jungle
aprox 100 kilometers away from the nearest towns
depending on the type of shake if landslides block a majour river then that damn breaks it could wipe out one of those towns, maybe 2.
but... i think its too deep to have that risk
