Mauna Kea is a dormant volcano on the island of Hawaii.
There are 169 volcanoes in the U.S. Most of them are in Alaska, California, Washington state and Hawaii. The U.S. Geological Survey has designated 14 of the volcanoes in these states as "Very High Threat Volcanoes." These volcanoes have previously devastated large areas with lava and mud flows, noxious gases and ash clouds.
Alaska
The Akutan volcano on Alaska's southwestern peninsula stands at more than 4,265 feet high. The volcano last erupted in 1992. On the same peninsula, the Makushin volcano is a stratovolcano that last erupted in 1995. The Augustine volcano is in the Cook Inlet of southern Alaska. The Redoubt volcano, which last erupted in 1990, is located just west of the Cook Inlet about 100 southwest of Anchorage. The Spurr volcano, located 78 miles west of Anchorage, last erupted in 1992.
California
Lassen volcano stands at 10,456 feet and is the southernmost volcano in the Cascade Range of northern California. It has only erupted once in the last two centuries, the last time being in 1917. The range also contains Mount Shasta, which last erupted in 1786. In eastern California, the Long Valley Caldera and the Mono-Inyo Craters chain form a large volcanic complex that has been the site of at least 12 volcanic eruptions in the past 1,000 years.
Hawaii.
Kilauea is the youngest and southeastern most volcano on the Big Island of Hawaii. Since it last erupted in 1983, the volcano has continued to deposit lava into the sea. Mauna Loa is the earth's largest volcano, most of which is submerged below the sea. It last erupted in 1984, the 33rd eruption since 1843.
Washington
The eruption of Mount St. Helens, located 96 miles south of Seattle, in 1980 killed 57 people and is the deadliest volcanic event in U.S. history. Mount Baker volcano is located in the North Cascades of Washington. It stands at 10,777 feet high and last erupted in 1880. Glacier Peak is the remotest of Washington's five active volcanoes and has produced some of the state's largest eruptions, the last of which occurred around 1700. At 14,412 feet, Mount Rainier is the highest peak in the Cascade Range. It last erupted in 1825 and is expected to erupt again within the next few hundred years.
