Longitude:121.695 W Also, visit the Cascades Volcano Observatory Mauna Loa, in Hawaii, could qualify for this category, since it experiences ground inflation and earthquakes that are a testament to changes within the volcanos magma chamber. New research results suggest that magma sitting 4-5 kilometers beneath the surface of Oregon's Mount Hood has been stored in near-solid conditions for thousands of years. Summary. fast-moving pyroclastic flows. live, work, or go to school in a volcano hazard zone. We called this the Falls Mountain, or Timm Mountain." Updated by the minute, our Dallas Cowboys NFL Tracker: News and views and moves inside The Star and around the league . University of Washington, Geophysics Program, Related Fact Sheets and Open-File Reports, Living With Volcanic Those flows quickly melted the snow and ice and mixed with the meltwater to create violent slurries as thick as concrete that traveled huge distances. Mount Hood has erupted episodically for about 500,000 years and hosted two major eruptive periods during the past 1,500 years. for those with respiratory problems, the elderly, and infants. 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). [59], Technical ice axes, fall protection, and experience are now recommended in order to attempt the left chute variation or Pearly Gates ice chute. Elevation:3,426 (m) 11,240 (f) [11], The mountain has six ski areas: Timberline, Mount Hood Meadows, Ski Bowl, Cooper Spur, Snow Bunny, and Summit.

Awards database: nsf.gov/awardsearch/, Follow us on social Mount Hood is a potentially active stratovolcano in the Cascade Volcanic Arc. It is located about 80 km (50 mi) east of the Portland metropolitan area. Many maps distributed in the late 19thcentury cited 18,361ft (5,596m), though Mitchell's School Atlas gave 14,000ft (4,300m) as the correct value. Lt. Broughton named the mountain after Samuel Hood, 1st Viscount Hood, a British Admiral at the Battle of the Chesapeake. River now stands, the lahar was 400 feet deep. [60], As of May 2002, more than 130 people had died in climbing-related accidents since records have been kept on Mount Hood, the first in 1896. Take Mount Thielsen, in Oregon. "For Mount Hood, the threshold seems to be about 750 degrees (C)if it warms up just 50 to 75 degrees above that, it greatly decreases the viscosity of the magma and makes it easier to mobilize." "Old Chute," West Crater Rim, etc.). During both recent eruptive periods, growinglavadomeshigh on the southwest flank collapsed repeatedly to formpyroclasticflowsandlaharsthat were distributed primarily to the south and west along the Sandy River and its tributaries. At that time the river was choked with sediment generated by erosion of the deposits from the eruption, which had stopped about a decade before their visit. Hopefully the USGS is correct in this instance. In fact, according to Volcano Discoverya total of 28 different volcanoes are erupting right now. That mountain is all that remains of a volcano that might have once looked like Mount Hood does today, but it last erupted about 300,000 years ago, and since that time erosion has worn away much of the ancient volcanos cone. Hood could have a significant eruption within the next 75 years. All three might be considered extinct, since none have erupted in the Holocene, but we know that magma is present beneath all three caldera systems because of geophysical unrest (including seismicity and ground deformation) and/or hydrothermal activity. Two people in Thomas J. Dryer's 1854 expedition calculated the elevation to be 18,361ft (5,596m) and the tree line to be at 11,250ft (3,430m). Even among dormant volcanoes there could be a sub-category for those that are restlessthese are volcanoes that are not erupting, but that are experiencing some signs that magma is accumulating or moving beneath the surface. However, even minor amounts of tephra can damage machinery For more information or copies of the paper version of this fact sheet contact: U.S. Geological Survey A recent eruption from the volcano, which is located in Italy, spewed ash over the Sicilian town of Zafferana Etnea. continuously monitor Mount Hood for signs of unrest and are in communication with responsible The most recent volcanic activity occurred in 1907, but it was very minor. Although hot magma from below can quickly mobilize the magma chamber at 4-5 kilometers below the surface, most of the time magma is held under conditions that make it difficult for it to erupt. [55] It has convenient access, though it presents some technical climbing challenges. While it last erupted in 1907 and still has active fumaroles, it is now considered a dormant volcano. 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). Credit and Larger Version, Gray volcanic deposits form ridges along the southeast and southwest flanks of Mount Hood. Lewis and Clark's expedition to the Pacific Northwest. Distal hazard zones (D) are areas adjacent to rivers that are pathways for lahars. Scientists from the U.S. If you have ever been in the middle of a seismic event that large, than you know how frightening it can be to have literally everything around you shaking violently. Amer. Water from the Bull Run Watershed, vital to Portland, is transported in pipes that cross Cheryl Dybas, NSF, (703) 292-7734, email: cdybas@nsf.gov The time it takes to liquefy and potentially erupt, however, is surprisingly short--perhaps as little as a couple of months. Renewed activity at most volcanoes begins with increasing numbers of About 10,000 people attempt to climb Mount Hood each year. We think these changes are very small but one should still be aware of this possibility. Hood is one of several locations featured by . Volcanic history and details of Mount Hoodis summarized by pages at theCascade Volcano Observatory. steam vents, or fumaroles, near Crater Rock attest to heat below. [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]. cost of at least $13 million. formed by this event traveled the length of the Sandy River valley, depositing public.

The latest minor eruptive event occurred in August 1907. Well, at least extinct is easy, right? A case could be made for subdividing the active category into actively erupting and potentially active. Volcanoes like Klauea in Hawaii, Stromboli in Italy, Erebus in Antarctica, and Santiaguito, in Guatemala, would be considered actively erupting, since magma is reaching the surface in all those places (and many others!) They destroyed everything in their path. Heat from the deeper, hotter magma increases the temperature and lowers the viscosity of . Both were associated with eruptive activity that triggered earthquakes beneath the volcano as magma moves towards the surface. Hood is home to six ski areas and the nation's longest ski season. Just dont let it go extinct! event, although large by Mount Hood's standards, was only about one-tenth the At the river's mouth, where the town of Hood Tax ID#: 33-0051202 For some volcanoes, it is easy to say with confidence that they are extinct.

Volcanism occurs at Mount Hood and other Cascades arc volcanoes because of the subduction of the Juan de Fuca Plate off the western coast of North America. "What's encouraging is that modern technology should be able to detect when the magma is beginning to liquefy or mobilize," Kent said, "and that may give us warning of a potential eruption. New active earthquake faults discovered under Mount Hood could Is it just a coincidence that so much shaking is happening all over the planet at the exact same time? and the other about 200 years ago. inundation areas for lahars of a size similar to lahars that swept through the Sandy River The volcano has grown in fits ", 1300 SE Cardinal Court STE 100 It will at some point, which is why monitoring restless volcanoes is so vital for forecasting their behavior on timescales that are helpful to society. Thus, areas within hazard zones PA and DA have a higher probability of There are many volcanic systems, however, that can go quiet for thousands of years and then reawaken.

The Cascade Volcanoes (also known as the Cascade Volcanic Arc or the Cascade Arc) are a number of volcanoes in a volcanic arc in western North America, extending from southwestern British Columbia through Washington and Oregon to Northern California, a distance of well over 700 miles (1,100 km). When the subject of volcanoes comes up, youll often hear the words active, dormant, and extinct. But what precisely do they mean? It will at some point, which is why monitoring restless volcanoes is so vital for forecasting their behavior on timescales that are helpful to society. #95, 818-832) studied the early swarms in great detail. The sheer size of these systems is also important, since big volcanic systems tend to experience long periods of inactivity between eruptions. reflect a vent located on the volcano's west, north, or east flank. Mount Hood | U.S. Geological Survey The Holocene cutoff is completely arbitrary, after all, and the Smithsonians Global Volcanism Program (which has a website at https://volcano.si.edu/ that we highly recommend and that includes information about all currently erupting volcanoes worldwide, as well as those that are active but not erupting) has expanded their catalogs to cover all volcanoes that have erupted as far back as the Pleistocene geological epoch, which started about 2.5 million years ago, to better capture all volcanoes that might still be active. boulders as large as 8 feet in diameter, 30 feet above present river level where Credit and Larger Version, All appears quiet today on Mount Hood.
