Mount Redoubt in Alaska is an active volcano. [11], The mountain has six ski areas: Timberline, Mount Hood Meadows, Ski Bowl, Cooper Spur, Snow Bunny, and Summit. A section of U.S. 26 and several of the Villages at Mount Hood (Zigzag, Welches, Wemme, and Wildwood) are built on lahar deposits of Timberline age. Similar deposits were probably formed in Mount Hood's past but were largely eroded, especially during ice ages, and are poorly represented in the geologic record. "Old Chute," West Crater Rim, etc.). Astronaut photograph ISS020-E-28123 was acquired on August 5, 2009, with a Nikon D3 digital camera fitted with an 800 mm lens, and is provided by the ISS Crew Earth Observations experiment and Image Science & Analysis Laboratory, Johnson Space Center. Cosigina is a stratovolcano, which is a cone-shaped volcano formed by alternating layers of solidified lava and volcanic rocks produced by explosive eruptions. While hot springs and steam vents are still active on Mount Hood, the last eruption from the volcano occurred in 1866. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. The Forest Service recommends several other route options due to these changes in conditions (e.g. A powerful explosion sent an ash column of 20,000 ft (ca. David A. Johnston Cascades Volcano Observatory
The Timberline Trail, which circumnavigates the entire mountain and rises as high as 7,300ft (2,200m), was built in the 1930s by the Civilian Conservation Corps. Image of the Day However, there have been some occasional earth tremors from the mountain. Hood's last major eruption occurred in the 1790s before Lewis and Clark's journey to the Pacific Northwest. Mount Hood has a long eruptive history. Lens artifacts have been removed. discharged into the Columbia River. . Below you will find an epicenter map, time-depth plot and seismicity plot for a region around Mount Hood for the three decades, 1980 - 2010 that shows typical or background levels of earthquakes in this region. Individuals too can prepare by doing the following: A few moments spent now could help keep the next eruption of Mount Hood from becoming a

[33], Three monitoring stations were eventually installed on Mount Hood in 2020.[34]. Mt. event, although large by Mount Hood's standards, was only about one-tenth the
We think these changes are very small but one should still be aware of this possibility. Smaller or larger lahars will affect smaller or larger areas, respectively. Located in the Chigmit Mountain subrange in Lake Clark National Park and Preserve, the 10,016-foot (3,053 m) volcano lies approximately 134 miles (215 km) southwest of Anchorage on the west side of lower Cook Inlet. Acinder conewith flanking lava flows formed The Pinnacle on Hoods north flank about 130,000 years ago. Did you know that the state of Oregon has several "active" volcanoes? The most obvious are a series of stratovolcanoes including Mount Hood. Mawenzi, Shira, and Kibo are the three volcanic cones found on Kilimanjaro. [58] The most popular route, dubbed the south route, begins at Timberline Lodge and proceeds up Palmer Glacier to Crater Rock, the large prominence at the head of the glacier. COOPERATING ORGANIZATIONS
More impressive, however, it rises an astonishing 30,000 . Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. fumarole gas, whose composition indicates that magma lies a few miles below the

Flight Center. summit collapsed. rigure s: Mazara zones arouna mi. Lahars pose the greatest hazard because more people live downstream in lahar-prone
stratovolcano 3426 m / 11,240 ft Oregon (Canada and USA (mainland)), 45.37N / -121.7W Current status: normal or dormant (1 out of 5) It is at this time topped with snow. "The last eruption of Mount Rainier was about a thousand years ago. Although it doesn't receive as much attention as Mt. At PNSN we use the following: Md (Duration Magnitude) - based on the duration of shaking. In contrast to the long-lived activity at Hood, each of these regional volcanoes was active for a relatively short period . [8], Older glaciation produced moraines near Brightwood and distinctive cuts on the southeast side; they may date to 140,000 years ago.[8]. The largest earthquakes were felt at Timberline, Brightwood, Parkdale, and Mount Hood Meadows. Ropes, ice axes, crampons and other technical mountaineering gear are necessary. Located in Skamania County, Washington, the volcano is widely known for its deadly eruption in 1980, which is the deadliest and most economically destructive volcanic eruption in the history of the United States. The Hogsback terminates at a bergschrund where the Coalman Glacier separates from the summit rock headwall. gases, or by deformation of the volcano's flanks. The last natural disaster caused by Mount Hood was back in 2002 which claimed the life of good 200 people living in the nearby towns. though based on its history, an explosive eruption is unlikely. This detailed astronaut photograph shows the summit crater of Mexicos Popocatepetl Volcano on February 7, 2009. In the astronaut photo from August 5, 2009, bright white glaciers cap the summit of Oregons Mount Hood, while gray volcanic deposits line the rivers that drain the mountain, and green forests cover the lower slopes. Iceland has recorded more than 40,000 earthquakes in the past three weeks. It is located approximately 75 km ESE of Portland, OR. NOTE: A depth of 0.0 (zero) km is at sea level and thus events within the volcano will plot above sea level (negative depths). NOTE: In Feb. 2012 a very small earthquake swarm took place resulting in ablog postingon the PNSN web pages. A geologist at Portland State University saidin 2019: Im all for protecting wilderness but this is just a question of public safety., And I think letting a helicopter in to put some instruments in that can then be monitored remotely seems like a pretty minor exception to the wilderness policies.. In addition to Mount Hood, other volcanoes scattered through the nearby area have erupted during the past 500,000 years. Jefferson is presented on the Cascade Volcano Observatory homepage of the U.S. Geological Survey. "restless," thereby providing some warning to officials and the
First sighted in 1792 by the English navigator . It is probably the only volcano in Oregon which has erupted in historic times (last confirmed activity in 1865-66). In general, more arrival-time observations result in improved earthquake locations. [62] Around 50 people require rescue per year. Minor amounts of tephra can make breathing difficult
Don't worry, though: It is unlikely to blow its top like nearby Mt. and lahars. Modern sources suggest the peak of Mount Hood is around 11,249 feet, however, this figure has changed throughout the years. In addition to being Oregon's highest mountain, it is one of the loftiest mountains in the nation based on its prominence, and it offers the only year-round lift-served skiing in North America.

Large Holocene mudflows from collapse have reached as far as the Puget Sound lowlands. Lt. Broughton observed its peak while at Belle Vue Point of what is now called Sauvie Island during his travels up the Columbia River, writing, "A very high, snowy mountain now appeared rising beautifully conspicuous in the midst of an extensive tract of low or moderately elevated land [location of today's Vancouver, Washington] lying S 67 E., and seemed to announce a termination to the river." at Forked Butte, south-southeast of the main volcano. Their great anger led to their transformation into volcanoes. [56] Peak climbing season is generally from April to mid-June. For technical reasons several different magnitude scales are in common use. Seismicity at Mount Hood is primarily characterized by fairly intense swarms of micro-earthquakes which typically occur about 4 to 7 km south of the summit. Hazard zones

Like other glaciers in the Pacific Northwest, the Hood glaciers have been receding due to global warming, and they have lost an estimated 61 percent of their volume over the past century. Mount Hood is a potentially active stratovolcano in the Cascade Volcanic Arc.It was formed by a subduction zone on the Pacific coast and rests in the Pacific Northwest region of the United States.It is located about 50 mi (80 km) east-southeast of Portland, on the border between Clackamas and Hood River counties. Mount Hood, highest peak (11,239 feet [3,425 metres]) in Oregon, U.S., and the fourth highest peak in the Cascade Range, 45 miles (70 km) east-southeast of Portland. Yes, Mt. significant quantities of snow and ice to produce lahars that flow down river
