Thing About the Mount Hood

The Mount Hood is a stratovolcano. The type of lava that forms Mount Hood is mafic magma felsic magma. The eruption it produces is the effusive eruption.

Around The Volcano

A town that is around the volcano is Hood River. “If the temperature of the rock is too cold, the magma is like peanut butter in a refrigerator,” Kent said. “It just isn’t very mobile. For Mount Hood, the threshold seems to be about 750 degrees (C) – if it warms up just 50 to 75 degrees above that, it greatly decreases the viscosity of the magma and makes it easier to mobilize.” Mount Hood's last major eruption occurred in the 1790's not long before Lewis and Clark's expedition to the Pacific Northwest. In the mid-1800's, local residents reported minor explosive activity. Mt, Hood last errupted in 1790.
