Will we soon have an
eruption of the El Hierro Volcano in the Canary Islands? According
to Volcano Discovery, the scenario of this happening in the NEAR FUTURE
is becoming increasingly likely. In fact, there is now a Red Alert and
evacuations going on in La Restinga as shared in the first video below.
Check out the map above of recent seismic activity in the area;
something is surely getting ready to happen with 155 earthquakes above
magnitude 2 today (Saturday) alone. What might an El Hierro eruption
mean to North America and the world? John Moore discussed that
possibility previously in the 2nd video below. First, from Volcano
Discovery:
The seismic swarm continues with even increasing intensity,
as to both the average magnitude and frequency of earthquakes, as well
as amplitude of harmonic volcanic tremor which is oscillating between
higher and lower phases. This might correspond to some sort of “stop and
go” behavior of magma moving its way through new cracks in the lower
crust beneath the island. The location of the epicenters of quakes, the
presumed location of the current magma intrusions, is now about 5 km NW
of the western tip of the island, and at depths between 10-17 km. No
strong upwards trend is yet visible, but this could change quickly.
Today’s earthquake count so far:
- 155 earthquakes > mag 2
- including 15 between M3-3.5
Earthquakes continue with increasing magnitudes
Update Sat 23 Mar 16:41
The scenario of an eruption in the near future is becoming increasingly likely:
- Volcanic tremor continues, suggesting magma is still moving although
mostly laterally for the time being to an area just north off the
western tip of the island.
- Earthquakes continue at high frequency and increasing magnitudes (more
than 90 quakes above magnitude 2, including 8 of magnitudes 3-3.5 so
far today). Their epicenters have remained at 14-16 km depth mostly,
with some shallower events as well.
- Deformation of the western part of the island continues to increase,
with vertical uplift reaching about 5 cm on some stations in the
westernmost part of the island.
