Most People Don’t Know There Are 4 Active Volcanoes Right Here In Northern California

We see plenty of forces of nature here in Northern California from earthquakes to flooding to wildfires. But did you know that we can add four active volcanoes to that list? They are located in the lower Cascades and all the way down into Lake County. You might be surprised by some of the familiar landmarks listed below that are actually volcanic areas.

The definition of a volcano is a rupture in the crust of a planetary-mass object (like the earth) that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. We’ve been living among these dormant but active volcanoes and now that you know the truth, do you look at these familiar landmarks differently?
