Canary Islands Red Alert: “Eruption At El-Hierro In Near Future Increasingly Likely”


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.
