This is a wiki about the amazing and most spectacular volcanoes in the United States. This wiki will show the statuses of every volcano in the United States, including some background information on each volcano. Updates on the wiki, including each volcano, will be weekly. If there was ever to be a major event or events at any volcano in the United States, that particular volcano will be updated more weekly than daily. If you are troubled by the way we categorize or level statuses of volcanoes please read the Volcano Alerts and Types of Volcanoes pages. If there is a volcano that you see we have missed, feel free to contact an administrator so we can include the excluded volcano.
The Cleveland volcano continues to be disruptful as it has been above its normal background for months now. It was recently lowered to Advisory level due to its activity decrease, but the volcano could awaken at any time. The USGS says that the volcano is currently more stable than dangerous since the volcano's thermal and seismic has decreased as well. The volcano has been mostly been obscured by clouds throughout the past week and nothing unusual has been observed during routine satellite observations. AVO has received no additional reports of activity.
The USGS is continuing to watch the Kilauea volcano as it continues to be unresful. The USGS states that the Kilauea volcano is currently continuing to erupt at two locations: At the summit, tilt leveled off and the lava lake is fairly stable. At Pu`u `O`o cone, lava flows continue to spread out on older flows to the north at the base of the cone. To the southeast of Pu`u `O`o, lava are entering the ocean in multiple areas both inside and outside the National Park boundary. Gas emissions are elevated.
Mount Baker (Lummi: Qwú’mə Kwəlshéːn; Nooksack: Kw’eq Smaenit or Kwelshán), also known as Koma Kulshan or simply Kulshan, is an active glaciated andesitic stratovolcano in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States. Mount Baker has the second-most thermally active crater in the Cascade Range after Mount Saint Helens. About 31 miles (50 km) due east of the city of Bellingham, Whatcom County, Mount Baker is the youngest volcano in the Mount Baker volcanic field. While volcanism has persisted here for some 1.5 million years, the current glaciated cone is likely no more than 140,000 years old, and possibly no older than 80-90,000 years. Older volcanic edifices have mostly eroded away due to glaciation.
After Mount Rainier, Mount Baker is the most heavily glaciated of the Cascade Range volcanoes; the volume of snow and ice on Mount Baker, 0.43 cu mi (1.79 km3) is greater than that of all the other Cascades volcanoes (except Rainier) combined. It is also one of the snowiest places in the world; in 1999, Mount Baker Ski Area, located 14 km (8.7 mi) to the northeast, set the world record for recorded snowfall in a single season—1,140 in (2,900 cm).
