Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido información de la Agencia Espacial NASA, sobre la erupción del Volcán Wolf en las Islas Galápagos, ubicado en la Isla Isabela.
NASA, nos dice: A finales de mayo de 2015, el volcán más alto de las Islas Galápagos entró en erupción por primera vez en 33 años. La erupción explosiva en el volcán Wolf en la isla Isabela envió gases volcánicos y ceniza de aproximadamente 15 kilómetros (50.000 pies) en el cielo, mientras que la lava fluyó a través de una fisura, por las laderas este y del sudeste, y con el tiempo llegó a la mar. A principios de junio, los flujos de lava ricos en azufre en las laderas parecían calmarse.
Esta imagen de Lobo fue adquirido el 11 de junio de 2015, por el espacial avanzado de emisiones y Reflection Radiometer (ASTER) en el satélite Terra. La imagen en falso color combina luz del infrarrojo cercano, rojo y verde (ASTER bandas 3-2-1), con zonas con vegetación que aparecen en el carbón generalmente aparecen de color rojo y lava o negro.

In late May 2015, the highest volcano in the Galapagos
Islands erupted for the first time in 33 years. The explosive eruption
at Wolf volcano on Isabela Island sent volcanic gases and ash roughly 15
kilometers (50,000 feet) into the sky, while lava flowed through a
fissure, down eastern and southeastern slopes, and eventually reached
the sea. In early June, the sulfur-rich lava flows on the slopes
appeared to subside.
This image of Wolf was acquired on June 11, 2015, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite. The false-color image combines near-infrared, red, and green light (ASTER bands 3-2-1), with vegetated areas appearing in red and lava generally appearing charcoal or black.
From June 12-16, seismologists from Ecuador’s Instituto Geofisico-Escuela Politécnica Nacional (IG) detected increased activity inside the caldera near the southern rim. The 7-kilometer (4 mile) wide caldera is nearly 700 meters deep. New lava is paving over deposits that were laid down in a 1982 eruption. Wolf is a shield volcano, with relatively broad but gentle slopes (like a Polynesian warrior’s shield) where one lava flow tend to spread out across previous flows. The volcano rises 1,710 meters (5,609 feet) above sea level, sitting near the equator and atop a volcanic hot spot.
In the early days of the 2015 eruption, conservation groups feared for the safety of a rare species of pink iguanas, which are only found on Isabela Island, and for the local population of giant tortoises and yellow iguanas. Neither species has been endangered so far by the eruption because ash and lave have tended to flow east and southeast, while the animals live mostly to the north and west of the summit.
