Mount Shasta in California has had multiple eruptions over the past 5,000 years. The most recent confirmed eruption occurred around 1250 AD, but there have been smaller events since then. The volcano is still considered active and closely monitored by geologists for any signs of future eruptions.

What type of cone does mount shasta have?
Mount Shasta is a stratovolcano, which is a type of volcano characterized by a steep-sided cone shape and explosive eruptions due to volatile-rich magma.
Was mount shasta formed on a hot spot?
Yes, Mount Shasta was formed on a hot spot. It is a stratovolcano located in northern California that formed as a result of successive eruptions fueled by the movement of the Pacific Plate over a stationary mantle hotspot.
Is mt shasta a explosive or a non-explosive volcano?
Mount Shasta is considered a potentially explosive stratovolcano due to its composition of andesite and dacite lava which can lead to explosive eruptions. However, its most recent eruptions have been relatively non-explosive with mainly effusive lava flows.
When was Mount Shasta's last eruption?
Mount Shasta's last known eruption occurred around 1786. Since then, there have been no recorded eruptions, and the volcano is currently considered to be dormant.
What California mountain was made by volcanic eruptions?
Mount Shasta in California was formed by volcanic eruptions. It is a potentially active stratovolcano in the Cascade Range.
Was mount shasta's eruptions explosive or gentle?
it was gentle

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.

What California mountain was made by volcanic eruptions?
Mount Shasta in California was formed by volcanic eruptions. It is a potentially active stratovolcano in the Cascade Range.
What is Mount Shasta made of?
Mount Shasta is made primarily of volcanic rock, including layers of andesite, dacite, and basalt. These rocks were formed from past eruptions of the stratovolcano that makes up the mountain. Additionally, there are layers of glacial deposits and sedimentary rocks in the area.
Does Mount Shasta have high silica?
Yes, Mount Shasta has high silica content in its volcanic rocks. Silica-rich magma is one of the reasons for the explosive nature of some volcanic eruptions in the region.
What kind of lava does Mount Shasta have?
Mount Shasta primarily produces andesitic lava, which is a type of intermediate lava characterized by a medium viscosity and silica content. This type of lava typically results in eruptions that produce a combination of lava flows and explosive eruptions.
How many people died when mount shasta erupted?
The last eruption was in 1786. There were several Native American tribes who lived within view of Mount Shasta since the time of the first Euro-American contact in the 1820's. It is not known how many people were killed, since there is no written historical record kept by those tribes.
Is Mount Shasta a shield volcano?
No. Mount Shasta is a stratovolcano.
