Volcanoes and Possibilities of Earthquakes

24 Nov

In addition to the civilizing crisis, the forces of nature seem to be more awake than usual, the volcano on the islands of La Palma, in the Canary Islands, a territory of Spain, arouses great interest in the volume of lava that I expect to arrive close in two months and without give signs of truce.

The earthquakes, the number of mouths opened by the volcano (there are now 5), the seriousness of the situation on the island which, despite being confined, has not been carried out any large-volume evacuation, have sparked debates even in the scientific world, the last one is about an earthquake of depth 3.4 or 34 km that happened these days, because the smaller depth would indicate new lava mouths and a greater risk for some abrupt change in the structure of the island which is composed of faults in its interior and large cliffs. depressions towards the sea.

There are several active earthquakes, some are of the Strambolian type, they are volcanoes with explosive eruptions such as emission of essentially effusive lava, and ejection of ash and gases such as sulfur, in incandescent lavas, also launching volcanic rock bombs that are launched from tens to hundreds of meters high, the Cumbre Vieja de La Palma volcano is of this type, in addition to attracting more attention, it is actually more dangerous, due to the terrain where lava can reach, the gases and, in some cases, the deformation of the terrain.

They are linked to the earthquakes that are a result of the Earth’s plate movements, and the biggest concern is not this island located in the Atlantic Ocean, but because it may be a small-scale representation of what can happen on a larger scale in the Pacific Ocean where there is a great circle of fire, name given to a large planetary junction of regions of volcanoes and quite frequent earthquakes and where the possibility of a Big One, a large earthquake from the San Andres fault on the American plate, is speculated.

The real possibility in La Palma is a small tsunami near the island, the consequences would no doubt be devastating, would it be large earthquakes in the circle of fire, or the eruption of large volcanoes like the Yellowstone Volcanic Chair, the Hawaiian Kilauea volcano on which they exist. just sensational speculations.

The consequences in La Palma are still unknown, but the volcano is still active and rather than calming down, these days were one of big explosions and strong earthquakes.
