Volcanic Hazards at Three Sisters Three Sisters is a potentially active volcanic center that lies close to rapidly growing communities and resort areas in Central Oregon. Volcanic hazards in the region include eruption-triggered events such as fallout of tephra, pyroclastic flows, lava flows and domes, and lahars and flooding, as well as landslides from steep flanks, which need not be triggered by eruptions.

The history of volcanic activity of Mt. Hood and analyses of volcanic hazard zones around Mt. Hood are summarized in the USGS Open File Report Volcano Hazards in the Mount Hood Region, Oregon and in the accompanying map. Numerous small volcanoes occupy the area between Mount Jefferson and Mount Hood to the north, and between Mount Jefferson and the Three Sisters region to the south. These small volcanoes tend not to pose the far-reaching hazards associated with Mount Jefferson, but are nonetheless locally important. A concern at Mount Jefferson, but not at the.

Volcano hazards in the Mount Hood region, Oregon. Mount Hood is a potentially active volcano close to rapidly growing communities and recreation areas.
The most likely widespread and hazardous consequence of a future eruption will be for lahars (rapidly moving mudflows) to sweep down the entire length of the Sandy (including the Zigzag) and White River valleys. Volcano hazards in the Mount Hood region, Oregon (SuDoc I ) [U.S.
Geological Survey] on *FREE* shipping on qualifying : U.S. Geological Survey. The accompanying volcano-hazard-zonation map outlines areas potentially at risk and shows that some areas may be too close for a reasonable chance of escape or survival during an eruption.
Future eruptions of Mount Hood could seriously disrupt transportation (air, river, and highway), some municipal water supplies, and hydroelectric power generation and transmission in northwest Oregon and southwest Washington.

Hazards. Mount Hood is an active volcano close to rapidly growing communities, recreation areas, and major transportation routes and therefore imposes heightened risk.
Potential hazards include collapse of growing lava domes and generation of pyroclastic flows, which in turn melt snow and ice to form lahars that flow far down valleys; the long-term adjustment of river channels to the large quantities of volcanogenic sediment.
Mount Hood, Oregon in early Summer. When Mount Hood erupts again, it will severely affect areas on its flanks as well as locations far downstream in the major river valleys that head on the volcano. Volcanoes like Mount Hood are very episodic in their eruptive behavior, and have periods with frequent eruptions over decades to centuries, separated by dormant periods lasting centuries to thousands of.
Mt Hood 75 km ESE of Portland is Oregon's highest peak and one of the most prominent of the Cascades volcanoes. It is probably the only volcano in Oregon which has erupted in historic times (last confirmed activity in ). Andesite-dacite lava domes form the glacially eroded summit complex.
The main hazard from Mt Hood are posed by pyroclastic flows and mud flows (lahars) in case of an eruption. These would travel downstream river beds radiating from the volcano and threaten communities in this area. When Mount Hood erupts again, it will severely affect areas on its flanks and far downstream in the major river valleys that head on the volcano.
Volcanic ash may fall on areas up to several hundred kilometers downwind. The purpose of the volcano hazard report USGS Open-File Report (Scott and others, ) is to describe the kinds of.

For more information on hazard zones see text or for a more detailed map and description see Scott and others,Volcano Hazards in the Mount Hood Region, Oregon, U.S.
Geological Survey Open-File Report The volcanoes are the result of the slow slide of dense oceanic crust as it sinks beneath North America (subduction), which releases water and melts overlying rock. This rich volcanic zone contains the well-known landmark volcanoes, such as Mount St.
Helens, Three Sisters, and Crater Lake and approximately 2, other known volcanic features. An urban center in the path of such a force would be totally devastated. In Oregon, there are very few populated areas that would be affected by a lateral blast.

Mount Defiance (aboutyears old) on the south side of the Columbia River gorge and Lost Lake Butte northwest of Mount Hood are two examples of shield volcanoes. In addition one such shield volcano, theyear-old Cloud Cap volcano, erupted on the north flank of Hood from a vent only 5 kilometers or less from Hood’s summit.Mount Hood is Oregon's highest peak and an active volcano of the Cascade Range.
