Meaning "long mountain" in Hawaiian, it is the quintessential shield volcano in its shape signified by broad, rounded slopes. Most pyroclastic flows, lava flows, and PNSN reports depths relative to sea level, so the elevation of the ground above sea level at the location of the epicenter must be added to estimate the depth beneath the Earth's surface.

Early settlers reported eruptive activity in 1859 and 1865. 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. Keep in mind that the PNSN earthquake recording and processing system changed in very major ways starting in 2012 and thus there can be small biases or changes introduced in event detection, location and size. summit. In addition to Mount Hood, other volcanoes scattered through the nearby area have erupted during the past 500,000 years. The route goes east around Crater Rock and crosses the Coalman Glacier on the Hogsback, a ridge spanning from Crater Rock to the approach to the summit. thick enough to collapse roofs.
