[hi-juju]

Rock formations from cooled lava rocks from thousands of years ago! SO DOPEEEEEE! Caution when walking down, kinda rocky and wet, TEHEHE.

New island could be born near El Hierro

The bubbling caused by the steam and eddies from the underwater eruption is recorded on the island of El Hierro are visible today from the highlands of the fishing village of La Restinga, attended by locals and other sites El Hierro volcanic phenomenon to observe. The spot that appeared on Wednesday off the coast of La Restinga is technically considered the evidence of the eruption. That enormous spot has several greenish color and its darker side, which is found about two miles from the coast and 150 meters depth.

Experts predict four phases of eruption: the current generation of bubbles of lava, the emergence of a large plume of white steam, the visualization of small explosions on the sea of lava known as rooster tails and finally, once magma passes through the water surface, the appearance of a mouth, from which the lava would flow into a small island. The Pevolca, which has increased the exclusion zone air and sea to a perimeter of two kilometers from the mouth eruption, increased volcanic emergency lights to red level 1.

The lava is going to be accumulating on the bottom and, as the building is built under the sea, will decrease the depth. Gradually the vapor will rise and see a nice column of smoke. Then explosions may occur. Some scientists  state that, if these explosions occur, the magma could be fired a mile away because, at shallow depths, water pressure has no power to stop the magma. Yesterday it was estimated that the cone that built the magma may already be less than 150 meters to the surface, so that the explosions are quite likely in the coming hours. These explosions that scientists expect to occur in front of the El Hierro coast in a place clearly visible to the public, are generated by the interaction of magma, which is over 1,200 degrees of temperature. Then can emerge an island can give out bubbles of lava.

Another possibility that scientists are very much present at the moment is the occurrence of further mouths in the volcano which can eject lava. The only data that scientists have to locate is the crack. To manage this data, scientists constantly monitor the deformation of the island. In recent months it has been deformed enough (5 centimeters) and it now appears that process has slowed but has not diminished. Although other data suggest that, depending on the strength of the explosions, it may fall a shower of magmatic material on the people. This is what Ortiz himself called "rooster tail explosions" by the visual effect created on the sea.

The eruption fissure discovered on Saturday is located at 2.4 km out of the coast and at a depth of only 150 meter! If the eruption would continue on the present location for a prolonged time, scientists say ” a new island” will be born. What the Spanish press is calling Pyroclastics are just pieces of cooled lava (pumice). The images of hot ash still smoking when coming to the surface is the absolute proof that an eruption is going on the slopes of the volcano below the sea level. The video below has been shot by scientists from IGN and CISIC while overflying the affected zone by helicopter.

The images of hot pumice arriving at the surface waters is the 100% proof that the earlier coloring is really an eruption. Also the non-believers became believers at the end.

Villagers are mentioning “bubbles” coming up in the spotted area in the sea. We expect to receive fastly images from the bubbles as the many camera teams with their superior equipment will certainly be able to shoot detailed video from an event which can be seen by the naked eye.

Nobody knows the next phase of the eruption, but that everybody from the safety team is prepared that the eruption will gradually come close to sea level and that steam explosions cannot be excluded. In case the magma would reach the surface waters, local steam explosions might be generated.

Ramon Ortiz, a technician from the CSIC (Centro Superior de Investigaciones Científicas) is predicting that a new island is being formed at this moment and that the chance that it will happen now is evaluated as very probable, at least of the eruption process will continue a little longer.

The PEVOLCA meeting which took place in El Pinar at 13:00 today, did take some very important decisions. Among the most important are : - The Los Roquillos tunnel, very important for the inhabitants of the western part of the island (Frontera, etc) and Valverde (other side) will be reopened within 24 hours. - The evacuated people from La Restinga are allowed to return to their houses under strict conditions and IF the newly installed equipment will give green light. The main reason of allowing the return of the La Restinga inhabitants is the installation of hydrophones.  The hydrophone(s) is an additional instrument which allows security people and scientists to call an immediate evacuation if needed. An sound alert will be installed in the village of La Restinga. If it hurls people have to auto-evacuate towards El Pinar and Valverde. The news was brought by Paulino Rivera, the President of the Canary islands. Mr Rivera was applauded by the islanders for the PEVOLCA decision. (EarthquakeReport)
