A large M7.2 earthquake (M7.1 revised) has struck the South Indian Ridge , Southwest of Australia, North of Antarctica.
This newest M7.0+ earthquake follows last weeks round of earthquake / seismic unrest … which has now built into several new volcanic eruptions spanning the globe, and additional large earthquakes in areas we don’t normally see much activity.
Momotombo Volcano erupted in Nicaragua (Central America) after being silent for nearly 110 years. Mount Etna (Italy / South Europe) sent of the largest blast in the past 2 years. Mauna Loa volcano in Hawaii is showing seismic swarms and deformation taking place (sign of possible eruption). All this news occurred within just a few days of last weeks deep earthquake activity.
The deep earthquakes are usually followed by shallow movement, and volcanic eruptions. This time around was no exception to the “rule”.
Some of my longtime viewers and readers may remember the two large Indo-Australian plate earthquakes which struck in 2012… two of the largest earthquakes to strike in the past 10+ years, ranking (in magnitude) right up there with the Japan M8.9 mega-quake of 2011 when the two M8.2 + M8.3 earthquakes struck the Indian / Australian ridge.
The South Indian ridge is due South of the Indo-Australian plate boundary — seen in the graphic above looking like a long straight “line” undersea which extends directly South from West Indonesia towards Antarctica.
Here is my video from 2012 regarding the two large back to back earthquakes which struck the Indo-Australian plate:
