The rivers of fire that came out of the volcano in eruption Last Sunday are now an immense blackish structure whose movement is almost imperceptible, although it continues to expand and devastate land and housing in its path. The lava wash continues its advance from old summit towards the sea, but it makes it more and more slowly. A trend that will change, predictably, if it finds an inclination.
"He is losing speed because he has reached a flatter terrain and, for what he is seen, the magma that is coming out is more explosive; That means that it is more viscous and has less ability to flow, less speed. That is why the laundry is stopping, "explains Pablo Gabriel Silva, Geology Professor at the University of Salamanca.
The main lava was scrolled on Thursday to four meters per hour, in contrast to 700 meters per hour that reached Sunday or 200 meters at Tuesday. "Everyone is waiting for it to reach the sea ... and maybe or arrive. We do not know if it's going to come or not, "she smelters her. «If things follow, it will come. For what it is seen, the ability to advance is very small. It may take, if it goes at that speed, days or weeks to get there », Estima Silva. «Go slow motion».
«From the six eruptions of which there are records, all have been on this part of the island and all have issued casting that have come to the sea», Emenius intervene, Petrology and Geochemistry Professor of the Complutense University of Madrid and member of College of Geologists. «Will you get to the sea? We do not know. But, until now, the six that we know they have come all to the sea, "he adds.
"Obviously, from that of the seventeenth century we only have someone describing the eruptions and sending a report to the kingdom," Clarifies Anchochea. "But those of 1949 and 1971 are well documented, and that is now functioning in a similar way," she says. "That would give us an idea."
The Lava Fall Pausada has awakened great expectation, after the authorities foresee, at first, that it would begin to pour out on the ocean on Monday at 8:00 pm, local time. On Tuesday morning, all the media were pending that the expected meeting between magma and sea water was produced, but the laundry was practically stopped over everything.
"The truth is that I do not know why the arrival of water lava has become an event," he said on Tuesday morning, when an imminent outcome was still expected, the Stavros Meletlidis Vulcanologist, from the National Geographic Institute (IGN). . "There are more important things in this eruption, such as people's safety, I do not know what they are waiting to see, but ... I do not know if it is going to be disappointed," I anticipated at that time this expert.
The column that comes out of the crater reached the four and a half kilometers on Thursday. The experts have shown their concern about the ashes that the eruption is leaving in the atmosphere, so they maintain surveillance in case it is necessary to interrupt air traffic.
The front of the main casting reaches 12 meters high, while the lava extension widens up to 600 meters in some areas. It already occupies a total of 166 hectares of a land that will take long, perhaps centuries, to become a new land. It has destroyed 350 homes and buildings.
On the other hand, the experts pointed out on Thursday that seismic energy was beginning to be very slowly reduced, and the bulge of the land, which is around 20 centimeters, has stopped growing, which could be a sign that the eruption is stabilizing .
The volcano has already issued 26 million cubic meters of matter, more than double the 11 million that had been foreseen before eruption.Date Of Update: 23 September 2021, 21:59
