What is the name of the fault? The activity seems to be between 0-50km deep... that is rather shallow isn't it??
And no I have next to no knowledge of geology or plate tectonics beyond high school.
The fault is the Miyagi megathrust, which is part of a very active subduction zone, one of the most active on the planet. Yes, the activity is between 0-50 km. But more importantly, it indicates that the entire breadth, width, and depth of that fault was involved in the rupture, and is still moving to this day. 0-50 km is shallow.
This is what I understood. Does this Miyagi fault/ subduction zone extend towards and throughout the Philippines? What of the subduction zone off New Zealand... this has been ringing like a bell for the past 5 months that I am aware...nothing major though
