We now need to be on watch for the next several days in adjacent silent areas for possible shallower larger movement to result from the upwelling seismic pressure coming from below in the Asthenosphere.

As we have seen in the past, when a deep earthquake strikes near Japan, a few things normally happen shortly thereafter:

  1. Upwelling pressure causes a shallower larger earthquake in a nearby adjacent area to the deep movement
  2. Volcanic activity increases in areas nearby the deep epicenter , as well as on the opposite side of the Pacific (simultaneously within days of each other) via new eruptions at long dormant volcanoes, as well as large blasts at active volcanoes.
  3. The pressure transfers WEST along the Himalayan range, causing swarms of earthquakes along the Northern India border / Nepal / Afghanistan.
  4. The pressure transfers across the Pacific Plate to the EAST causing new larger earthquakes in the East Pacific, Pacific Northwest United States, Central America, + South America
