Location in geographic coordinates (as Latitude, Longitude in decimal degrees) of the position on Earth's surface directly above where an earthquake rupture initiated. The last eruptive period took place around 220 to 170 years ago, when dacitic lava domes, pyroclastic flows and mudflows were produced without major explosive eruptions. It exploded with a violent eruption in 1980. Mount Hood volcano, Oregon's highest peak, forms a prominent backdrop to the state's largest city, Portland, and contributes valuable water, scenic, and recreational resources that help sustain the agricultural and tourist segments of the economies of surrounding cities and counties. 6 km) height above the crater in less than a minute.

The largest glacier by surface area is the Coe-Ladd Glacier system at 531 acres (215ha). Mount Hood has had two significant eruptive periods, one about 1,500 years ago eruption-related problems. While some earthquake occur directly under the edifice most of the Mount Hood events likely are occurring on a fault or fault system located to the south of the volcano and represent either its reaction to regional tectonic stresses or possibly deep-seated volcanic stress below the region. debris avalanches will stop within the proximal hazard zone, but lahars can Hood has had three volcanic eruptions over the last 1,800 years. The resulting lahar moved downvalley at 25 to 35 miles per hour. Mount Hood, but few have been as destructive. swept down the Hood River valley.
