Crater Lake in Oregon was formed approximately 7,700 years ago following the collapse of Mount Mazama during a massive volcanic eruption. The volcanic caldera left behind was gradually filled with rain and snowmelt, forming the stunning lake we see today.


How does Mount Pelee eruptions occur?

Mount Pelee eruptions occur due to the buildup of pressure from magma beneath the surface. When this pressure becomes too great, it causes an explosive release of gases, ash, and lava. This can lead to devastating volcanic eruptions, as seen in the catastrophic eruption of Mount Pelee in 1902.


How many times has Mount Pinatubo erupted?

It's difficult to predict eruptions as records are not aways kept, or accurate. Mount Pinatubo is believed to have first erupted 17,000 years ago with successive eruptions throughout the years. Major eruptions have been identified at 9,000, 6,000, 5,000, 3,900, 2,300 and 450 years ago. There may have been many more minor eruptions. The last major eruption was in 1990/1991.

What type of volcano is Mount Mahuja?

Mount Mahuja is a stratovolcano, also known as a composite volcano. These are characterized by their steep-sided symmetrical cones and explosive eruptions due to the high viscosity of the magma. They typically alternate between explosive and effusive eruptions.


How were Mount Shasta and Lassen Peak formed?

Mount Shasta and Lassen Peak are both formed by volcanic activity. Mount Shasta is a dormant stratovolcano that has been shaped over thousands of years by eruptions and glacial activity. Lassen Peak is part of the southernmost portion of the Cascade Range and was formed by a series of eruptions in the early 20th century.
