Earthquakes

Magnitude 5+ Earthquakes - Global


5.9 Earthquake hits the southwest Indian ridge.


5.5 Earthquake hits Kepulauan Barat Daya, Indonesia.


5.2 Earthquake hits the central Mid-atlantic ridge.


5.0 Earthquake hits the Mariana Islands.


Iceland Earthquake Swarm


484 earthquakes in the last 48 hours.


The swarm continues and the most recently listed earthquakes had a Magnitude of M4.3 and M4.2.


The location of the swarm is a relatively shallow ridge area (the zigzagging ridge creates the transform-like earthquakes) . A ridge is a location where 2 tectonic plates are pulling away from each other. Fresh magma will have an easier job to reach the seabed and hot volcanic vents are often found on these locations. A new island in such an area is almost a certainty in the geological future.
