Curious when the last time Mt. The 2023 Mount Hood Eruption was an Explosive VEI 5 eruption that happened on December 9th, 2023. Although overridden by extensiveglaciersof the last ice age, many of the lava flows younger than 100,000 years display well-preserved lava-flow features such as levees and flow lobes. "Old Chute," West Crater Rim, etc.). debris avalanches and were accompanied by lava extrusion, pyroclastic flows, [25], The glacially eroded summit area consists of several andesitic or dacitic lava domes; Pleistocene collapses produced avalanches and lahars (rapidly moving mudflows) that traveled across the Columbia River to the north. Image of the Day Mount Hood has a long eruptive history. [1][43][44][45], Mount Hood is host to 12[46][47] [54], Mount Hood is Oregon's highest point and a prominent landmark visible up to 100mi (160km) away. Its edifice, capped by snow and 25 glaciers, has been built up by untold eruptions over the past 500,000 years. The farthest traveledpyroclastic flowreached about 12 km from the lavadome. . [26][27], The glaciers on the mountain's upper slopes may be a source of potentially dangerous lahars when the mountain next erupts. On May 18, 1980, Mount St. Helens, Washington, exploded in a spectacular and devastating eruption that brought the volcano to the attention of the world. The largest event in the roughly 15 sequences during the 1990s varied from M=1.6 to M=3.5. The primary conclusion of this study was that these swarms (maybe most) are related primarily to regional tectonic forces and do not necessarily have a volcanic origin. "The last eruption of Mount Rainier was about a thousand years ago. Latitude:45.374 N individuals time to move to higher ground and greater safety if given warning. The retreat released considerable outwash, some of which filled and flattened the upper Hood River Valley near Parkdale and formed Dee Flat. Following an apparently dormant period between about 12,000 and 1,500 years ago, the Timberline eruptive period producedlavadomeswith accompanying pyroclastic-flow andlahardeposits during two major pulses, each lasting a number of decades. Hawaii's Mauna Loa volcano last erupted between March 25 and April 15, 1984, following nearly two years of increased seismic activity. [31], The most recent evidence of volcanic activity at Mount Hood consists of fumaroles near Crater Rock and hot springs on the flanks of the volcano.[32]. In 2014, a USGS employee, Dr. Seth Moran, proposed installing new instruments on Mount Hood to warn of volcanic activity. Seeing what he had done, he erected three mountain peaks to mark where each fell. Mount Hood's last major eruption happened in the 1790's now not lengthy earlier than Lewis and Clark's expedition to the Pacific Northwest. and lahars.

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." B on the basis of the vent melted snow and triggered a small landslide in fragmental debris in upper Clark later noted that it was also Vancouver's Mount Hood. The largest earthquakes were felt at Timberline, Brightwood, Parkdale, and Mount Hood Meadows. Like other active volcanoes, it varies in height, increasing from deposition during eruptions and decreasing from the periodic . Image of the Day It was formed by a subduction zone on the Pacific coast and rests in the Pacific Northwest region of the United States. Alaska, Hawaii, Washington, Oregon, and northern California all have active volcanoes.

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. Mount Hood is an active stratovolcano one built up by many layers that is 50 miles south of Portland in Oregon. About 10,000 people attempt to climb Mount Hood each year. [8], During the last major glacial event between 29,000 and 10,000 years ago, glaciers reached down to the 2,600-to-2,300ft (790-to-700m) level, a distance of 9.3mi (15.0km) from the summit. While hot springs and steam vents are still active on Mount Hood, the last eruption from the volcano occurred in 1866. 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. Recent eruptions around the world volcanoes and the hazards they pose at the USGS [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. In addition to Mount Hood, other volcanoes scattered through the nearby area have erupted during the past 500,000 years. Soc.

In an article for the New York Times, award-winning journalist Shannon Hall wrote: The volcano is hardly monitored. 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. Early in the Timberline eruptive period, a large mass of older summit rocks avalanched down the southwest flank and formed a lahar that traveled the Zigzag and lower Sandy River valleys to the Columbia. Two past eruptions at Mount Hood provide perspective on the impact of named glaciers or snow fields, the most visited of which is Palmer Glacier, partially within the Timberline Lodge ski area and on the most popular climbing route. About 100,000 years ago, a large portion of the volcano's north flank and Amer. The resulting lahar moved downvalley at 25 to 35 miles per hour.

Lava flows about 40,000 to 50,000 years old that form Langille Crags and Stranahan Ridge and extend almost to Laurence Lake are the younger part of this sequence of scar-fillinglavaflows. The tallest mountain, Kibo, remains dormant and has the potential to erupt again, while Mawenzi and Shira are extinct. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. There are vents near the summit that are known for emitting gases such as carbon dioxide and sulfur dioxide. What will those from their source, have built up the flanks of the volcano one sector at a time. [8], Lewis and Clark spotted the mountain on October18, 1805. There are no trails to the summit, with even the "easier" southside climbing route constituting a technical climb with crevasses, falling rocks, and often inclement weather. This article is about the highest mountain in Oregon. Therefore, any attempt to restore the mountain's original indigenous name would require agreement on which language's name to use. inundation areas for lahars of a size similar to lahars that swept through the Sandy River Lens artifacts have been removed. Land Mount Hood's last major eruption occurred in the 1790's not long before Lewis and Clark's expedition to the Pacific Northwest. lahars that can reach the hazard boundary in less than 30 minutes, as well as The most obvious are a series of stratovolcanoes including Mount Hood. forming a lava dome many hundreds of feet high. Glaciers on Mount Hood retreated through the first half of the 20thcentury, advanced or at least slowed their retreat in the 1960s and 1970s, and have since returned to a pattern of retreat. Mount Hood, a 500,000-year-old stratovolcano located 50 miles east-southeast of Portland, last erupted in the 1790s, just before Lewis and Clark reached the Pacific Northwest. Today Mount Hood shows no signs of imminent volcanic activity, but hot Land. Elevation changes since the 1950s are predominantly due to improved survey methods and model refinements of the shape of the Earth (see vertical reference datum). Estimated [48] More than 80percent of the glacial surface area is above 7,000ft (2,100m). A powerful explosion sent an ash column of 20,000 ft (ca. Some earthquake swarm at Mount Hood, in particular January, 1999: An earthquake swarm began near Mount Hood in northern Oregon early Monday morning (Jan 11, 1999) and produced more than two dozen earthquakes that day, the largest of which were magnitudes 3.2 (at 2:04 pm PST) and 3.0 (at 8:54 am PST). 10. Composition:Andesite to Dacite Unlike its neighbor to the north, Mount St. Helens, Mount Hood does not It is located approximately 75 km ESE of Portland, OR. Swarms of these types of events are fairly common on many volcanoes. A measure of how well network seismic stations surround the earthquake. Hood has had three volcanic eruptions over the last 1,800 years. Number of P and S arrival-time observations used to compute the hypocenter location. better anticipate and prepare for future eruptive activity. [11], The mountain has six ski areas: Timberline, Mount Hood Meadows, Ski Bowl, Cooper Spur, Snow Bunny, and Summit. Renewed activity at most volcanoes begins with increasing numbers of On this Wikipedia the language links are at the top of the page across from the article title. In addition one suchshield volcano, the 425,000- year-old Cloud Cap volcano, erupted on the north flank of Hood from aventonly 5 kilometers or less from Hoods summit. Despite the physical consistency, the estimated elevation of Mount Hood has varied substantially over the years, as seen in the following table: Early explorers on the Columbia River estimated the elevation to be 10,000 to 12,000ft (3,000 to 3,700m). Older domes, many of which have been altered by hot fluids to white, yellow, orange, and red rock masses, form the rest of the summit region. Volcanic History . The remnants of such fans include (1) the bouldery ridge that rises from above Mount Hood Meadows to Steel Cliff and (2) the broad surface extending from Cooper Spur, below and to the east of the summit, which is deeply incised by Polallie Creek. at Forked Butte, south-southeast of the main volcano. residents reported minor explosive activity, but since that time the volcano has on the Web. Originally from UK, Laura is based in Axarquia and is a writer for the Euro Weekly News covering news and features. The resulting debris avalanche transformed into a lahar that Mount Hood, an active volcano in north-central Or-egon, poses significant volcanic landslide, flood, channel migration, and earthquake hazards to nearby communities and to the Portland, Oregon, metropolitan area. Wise W S, 1968. While hot springs and steam vents are still active on Mount Hood, the last eruption from the volcano occurred in 1866. Still, the odds of an eruption in the next 30 years are estimated at between 3 and 7%, so the U.S. Geological Survey (USGS) characterizes it as "potentially active", but the mountain is informally considered dormant.
