Question

The calbuco volcano in southern Chile erupted in 2015. Which of the following is most responsible for the eruption

Answer 1

Answer:

Calbuco volcano in southern Chile began erupting for the first time since 1972. An ash cloud rose at least 15 kilometers (50,000 feet) above the volcano, menacing the nearby communities of Puerto Montt (Chile) and San Carlos de Bariloche (Argentina). The eruption led the Chilean Emergency Management Agency and the Chilean Geology and Mining Service (SERNAGEOMIN) to order evacuations within a 20-kilometer (12 mile) radius around the volcano. About 1,500 to 2,000 people were evacuated; no casualties have been reported so far.
