Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 19000 ft (5800 m) altitude or flight level 190 . A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. Easter Island statues are known for their large, broad noses and big chins, along with rectangle-shaped ears and deep eye slits. The Three Sisters are closely spaced volcanic peaks in the U.S. state of Oregon.They are part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Washington and Oregon to Northern California.Each more than 10,000 feet (3,000 m) in elevation, they are the third-, fourth- and fifth-highest peaks in A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes Explosive activity continues. Hawaii officials are warning residents of the Big Island that the worlds largest active volcano, Mauna Loa, is sending signals that it may erupt. Explosive activity continues. Earlier eruptions built Mount Scott, which lies east of Crater Lake. 250-450 m deep crater. Commentaries are submitted to a specific journal but the audience is the broad Earth and space science community. An impact crater is a depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body.
