• This is a bit of a update that I have posted every year sense 2009. The reason that it is so important is that both El Hierro and her bigger sister la Playa both have huge cracks from previous quakes and when there is a big enough quake either or both could fall into the water and as they are mt. tops the ocean floor sits more than a mile below. When they fall, even just one of them, it will cause a tsunami wave that could be 1/2 to 1 mile high and wipe out the coast lines 50 miles in for all of the Americas and even hit Africa and Europe. Millions of live could be lost and very little time for warning as it will move at 300 mph. Another thing the MSM does not talk about is the nuclear waste dump in 55yr old steel drums that are now leaking and is one of 50 site burid  or parked in the the ocean world wide. The barrels were only made to hold the waste for 50 yrs and then they were supposed to be removed but was not. So this dump sits within 1/4 mile of El Hierro and so when it falls into the ocean the barrels will bust wide open and the resulting Tsunami will also be toxic. We need to keep a eye on this serious problem. We are warned to move away from the coasts for this reason, floods are a coming. Adonai. Rev. Joshua
• Earthquake swarm at El Hierro intensifies with an increase in CO2 emission

The intensity of ongoing earthquake swarm at El Hierro island increased on March 28, 2013. 119 earthquakes have been recorded so far at depths of 16-18 km. A few weaker quakes have also been recorded at lower depth of 7-10 km, possibly related to release of stress caused by the strong deformation, rather than intruding magma as was suspected before.

Latest measurements indicate CO2 emission levels have increased significantly than normal levels, suggesting fresh magma is arriving from deeper sources. Following graph shows a comparison between current levels (1684 ± 72 tons of CO2 per day) and levels of previous eruptions.

Also, many rockfalls have been noted from the steep cliffs in the western part of the island. Particularly along the road Frontera-Sabinosa during the more intense phases in the past days, with earthquakes as strong as 4.6.

3D animation of the 2011-2012 submarine volcano:

The Instituto Oceanografico has released a 3D animation of the new volcanic cone formed in 2011-12, using the new data obtained by the latest bathymetry mission of the Oceanographic Vessel Ramon Margalef:

El Hierro, nicknamed Isla del Meridiano (the “Meridian Island”), is the smallest and farthest south and west of the Canary Islands (an Autonomous Community of Spain), in the Atlantic Ocean off the coast of Africa, with a population of 10,162 (2003). The massive Hierro shield volcano is truncated by a large NW-facing escarpment formed as a result of gravitational collapse of El Golfo volcano about 130,000 years ago. The steep-sided 1500-m-high scarp towers above a low lava platform bordering 12-km-wide El Golfo Bay, and three other large submarine landslide deposits occur to the SW and SE. Three prominent rifts oriented NW, NE, and south at 120 degree angles form prominent topographic ridges.

The subaerial portion of the volcano consists of flat-lying Quaternary basaltic and trachybasaltic lava flows and tuffs capped by numerous young cinder cones and lava flows. Holocene cones and flows are found both on the outer flanks and in the El Golfo depression. Hierro contains the greatest concentration of young vents in the Canary Islands. Uncertainty surrounds the report of an historical eruption in 1793. (GVP)
