Another deep earthquake has struck the West Pacific. This newest event occurred at a depth of 300.7 miles / 484km, deep in the Asthenosphere.
As many of my viewers (and readers) know, whenever we see deep earthquakes in this region, it leads to shallower larger earthquakes in adjacent areas.
If you have no idea what I’m talking about, you can watch this video for a basic explanation:
We have seen deep earthquakes like this occur multiple times over the past several days, each time preceding a larger shallower earthquake in an adjacent area.
For example, first we saw deep asthenosphere earthquakes in the 4.0M+ range at Chile, which was followed by an unexpected volcanic eruption of Calbuco Volcano, and a shallow 5.7M earthquake at the border of Peru / Chile.
Then we saw two deep asthenosphere earthquakes in the 4.0M range near Japan and Fiji, followed by a swarm of shallow 6.0M+ earthquakes in Taiwan (which was NW of the deep earthquake epicenters).
Now we see another 5.0M earthquake in the Asthenosphere below Fiji, meaning we need to watch for another deep earthquake, and then a large shallow earthquake somewhere adjacent to the West / Northwest of this deep earthquake.

UPDATE 945pm CDT April 25, 2015:
Approximately 2 hours after posting this article ANOTHER deep asthenosphere earthquake has struck in the same location (Fiji) .. this one even deeper than the previous.. now at 374 miles down (603km) !
Serious pressure from underneath building towards a shallow earthquake above in an adjacent area to this deep movement! Be on watch, we’re not out of the woods by a long shot.
