How was Cerro Azul formed?

How was Cerro Azul formed?

It is also known as Cerro del Medio (“Middle Hill”) or Volcan Nuevo (“New Volcano”). The volcanic vent formed during an effusive eruption involving hornblende–dacite flows accompanied by tephra, and the crater was excavated by phreatic and Strombolian eruptions between 1907 and 1932.

What type of volcano is Azul?

The Cerro Azul stratovolcano is at the southern end of the Descabezado Grande-Cerro Azul eruptive system. It is a steep-sided edifice with a 500-m-wide summit crater open to the north.

What type of volcano is paricutin?

cinder cone volcano
A nine-year eruption (1943–52) of ash and lava from an open field in Michoacán state, Mexico, buries the nearby Tarascan Indian village of Paricutín and creates a new cinder cone volcano.

What are hot spots and what do they produce?

A hot spot is an intensely hot area in the mantle below Earth’s crust. The heat that fuels the hot spot comes from very deep in the planet. This heat causes the mantle in that region to melt. The molten magma rises up and breaks through the crust to form a volcano.

Is Azul volcano a hotspot?

Cerro Azul is one of the most active volcanoes of the Galapagos hot spot.

Which area on the South American continent would have the greatest risk of volcanic eruption?

The South Volcanic Zone is the most volcanically active region in Chile, and produces around one eruption per year. Its largest historical eruption was at Quizapu Crater, located on the north side of Cerro Azul’s summit (see below), and its most active volcanoes are Llaima and Villarrica.

Why is the Paricutin volcano important?

It is one of the Seven Natural Wonders of the World. It is famous because it is the youngest volcano to form in the Northern Hemisphere, developing in a farmer’s cornfield. The lava flow from the volcano smothered the Mexican villages of Paricutin and San Juan Parangaricutiro.

Why is the Paricutin volcano a wonder of the world?

Paricutin was named one of the seven natural wonders as an active volcano. The volcano has been dormant since the last eruption in 1952. It was established as a natural wonder because mankind witnessed its birth. The volcano was also fast growing reaching three-fourths of its size within the first year.

What type of volcano is Cerro Azul?

Cerro Azul stratovolcano in Central Chile is located at the southern end of the Descabezado Grande-Cerro Azul group of volcanoes. Its steep summit cone contains a 500 m wide crater. Cerro Azul is the site of one of the largest explosive eruptions in the 20th centuries.

What is the bathymetry of Cerro Azul?

William Chadwick has merged all available datasets (as of 1994) for bathymetry in the Galápagos region. Cerro Azul sits adjacent a steep drop-off to the W, with water adjacent the shore reaching ~ 3. 5 km depth. In contrast, much of the island cluster is on a broad shallow platform.

When was the last time Cerro Azul erupted?

Satellite thermal anomalies. The most recent previous eruption of the volcano took place in September 1998 (BGVN 23:08 and 23:09). In accord with the 10-year quiet period, thermal anomalies at Cerro Azul were absent at least as far back as 1 January 2000 and onward through 29 May 2008.

What happened to Cerro Azul’s magma intrusion?

IG reported that deformation data showed continued inflation after 20 March, indicating that the volume of the magma intrusion below Cerro Azul’s SSE flank had increased. Seismicity decreased after 25 March possibly signifying a halt in the intrusion.
