El Hierro: what a day !

The activity is amazing today. For the first time since long ago, multiple earthquakes with a magnitude greater than 4 were recorded in a very short period. This activity continues so far with no end in sight.

Other earthquakes with lower magnitude were recorded as well. They are too numerous to be displayed here.

The interesting point also, is that the evolution is rather scary, as more higher magnitude are recorded as time passes:

At the beginning, few earthquake with a magnitude greater than 3 were recorded (see the lack of purple bars). Now even magnitude 4 and above are becoming common.

Fortunately, the activity is located far at see:

There is also a tendency of the last earthquake to move a bit south. We'll see later if this is confirmed.

Stay tuned !

Update 22h00 UTC

The situation forced the PEVLCA to raise the alert level to yellow for the western part of the island.
