4.3 Earthquake Hits El Hierro, Canary Islands and possible Submarine Eruption
Translate: A 4.3 magnitude earthquake struck El Hierro, the smallest of The Canary Islands, late on Saturday night ( Oct. 8, 2011). It was the strongest earthquake to be recorded on the Spanish island since an unprecedented earthquake swarm commenced during the summer and has been felt throughout the island
This earthquake has not produced injury but there have been landslides on the road to La Restinga Tacorón, which has been partially blocked, and the outer slopes of Los Roquille tunnel.
The Instituto Geografico Nacional (IGN) has reported an increase in the intensity of earthquakes recorded on El Hierro, the smallest of The Canary Islands, during the last 48 hours. The number of earthquakes recorded since July 17 , 2011 on El Hierro has now reached 10,000, figures from the IGN confirm.
The agency confirmed on Friday that 886 earthquakes, most of them located in the sea to the SW of the island, have been recorded in the 7 days since 02 October, 2011. During this period, 71 earthquakes were felt by the island’s estimated 10,000 residents.
El Cabildo de El Hierro is producing a small submarine eruption at 500 meters deep and seven kilometers from the coast, particularly south of La Restinga. So far no official source has confirmed this, but according to testimony from citizens and residents of La Restinga, helicopters flying over the area where the rash is supposedly going underwater to confirm this fact. In addition, the coastal radio has asked all vessels to return to port and away from the above area, not to interfere in the work of scientists testing.
Maria del Carmen Morales, said in the media that this submarine eruption is occurring because “the earthquake of 4.3 occurred on Saturday afternoon caused a fissure, which is where energy is being released. Scientists do not know if it is a gas emission or lava, they will continue with the analysis of parameters”.
They confirmed that earthquakes continue to occur on the island although less frequently than in previous days.
According to John Moore, in a recent interview with Dr. Bill Deagle on the Nutrimedical Report, there is an increased possibility of a super mega-tsunami coming from the Canary Islands in the coming weeks.
El Hierro Volcano: Is one of the smallest of the Canary Islands, the origins of the island date back some 100 million years when the ocean floor shifted with the movement of the Earth’s mantle. The crust cracked into a three pointed star releasing flows of magma. After 3 eruptions, the island emerged from the ocean as an imposing volcano more than 2,000 meters high. It has now been over 200 years since the last eruption but El Hierro. Although being the smallest island, it has the largest number of volcanoes with over 500 open sky cones and another 300 covered by the most recent outflows. There has been uncertainty surrounding reports of a historical eruption taking place in 1793.
Meanwhile, scientific research is predicting that an eruption of the Cumbre Vieja volcano, at La Palma in the Canary Islands would result in a massive mega-tsunami that would reach the East Coast of America.
Geological evidence suggests that during a future eruption, Cumbre Vieja Volcano on the Island of La Palma may experience a catastrophic failure of its west flank, dropping 150 to 500 km3 of rock into the sea.
Using a geologically reasonable estimate of landslide motion, we model tsunami waves produced by such a collapse. Waves generated by the run-out of a 500 km3 (150 km3) slide block at 100 m/s could transit the entire Atlantic Basin and arrive on the coasts of the Americas with 10-25 m (3-8 m) height.
Lateral collapses of oceanic island volcanoes rank amongst the most spectacular natural events on Earth. Although no such lateral collapse punctuates the historical past, residual debris found on the seafloor evidence their abundance in recent geological time.
Moore (1964) first identified the remains of lateral collapses off the flanks of Hawaii. Since then, dozens have been recognized adjacent to island volcanoes in nearly every ocean (Moore et al. 1994; Keating and McGuire, 2000). These observations constrain not only the geography and frequency of lateral collapses, but also their magnitude (up to 5000 km3 of material), extent (to 300 km length) and ferocity (underwater speeds to 140 m/s).
