The building of the church in the town of Arona is already surrounded by lava. The new river of lava threatens even more buildings on La Palma. It’s been two weeks since the eruption started and nearly 6 miles 10 kilometers have been covered by molten rock so far. The big scar on the landscape is only accelerating.
The eruption of the Cumbre Vieja volcano on the island of La Palma began two weeks ago and has been described as one of the most spectacular in recent years (the last major eruption was that of 1949-1951). The potential danger for residents is no less because parts of this volcano area on the east of the island, which serve as a funnel so that the current stream of lava is inevitable. Since 18 July 2017 more than five km of rivers of magma-lava have been formed, but on Sunday it reached its maximum speed.
The equivalent of 2 million elephant elephants has already appeared in this eruption or enough to fill 5 million trucks full of elephants. During the eruption, the highest point on the island has already increased by about one centimeter and if it didn’t stop soon, then that might even raise to two centimeters.
Although it is difficult to predict how long such a long-term eruption can last, researchers said it could be months or years. However, if the eruption continued at its current pace, it’s possible that in a year or two enough magma could accumulate so that an eruption of the Cumbre Vieja volcano would be inevitable.

A team of volcanologists from the U.S. Europe, and Mexico have discovered a new volcano in the Galapagos Islands. They argue that this could be an important discovery for understanding how life developed on “the birthplace of evolutionary biology”. The presence of the new cone is confirmed by a high-resolution digital elevation model obtained with the help of LiDAR laser scanning.
Geologists have already investigated many volcanoes in the Galapagos archipelago, but this is the first time that new volcanic activity has been found on Isabela Island during recent years. The scientists suggest that the volcano was formed as a result of overlapping and coalescence processes between two older volcanoes, which are likely to have existed for several million years.
The construction of the new cone is more complex than it seems at first glance. The process begins with a formation of currents of molten rock, known as pahoehoe-type volcanoes that then start to merge into one another’s currents. According to Anthony Rathborne from the University of Texas at El Paso, scientists have been able to determine that this new cone is likely to be a pahoehoe type volcano.

According to a report published in Nature Communications, in the Galapagos Islands in Ecuador, there is a new volcano appeared in December 2015. The study was led by Gisela Winckler of NASA’s Jet Propulsion Laboratory in Pasadena (California), who argues that this volcano could help us better understand life on Earth and its development.
