The east side of Mount Baker in 2001. Sherman Crater is the deep depression south of the summit. Mount Baker (Nooksack: Kweq' Smánit; Lushootseed: təqʷubəʔ), [9] also known as Koma Kulshan or simply Kulshan, is a 10,781 ft (3,286 m) active [10] glacier-covered andesitic stratovolcano [4] in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States.
During recorded history, eruptions at Mount Baker have mainly occurred from Sherman Crater. The earliest historical eruption took place in 1843, with more recent eruptions having occurred in 1852–1853, 1854, 1858, 1859–1860, 1863, 1870 and 1880. These eruptions ranked 2 and 3 on the Volcanic Explosivity Index. Possible but unconfirmed ...
In addition to these eruptions traced to Black Buttes, there are five lava flows in the vicinity for which geologists have failed to pinpoint the source vent. These deposits were erupted after Black Buttes went extinct, but before Mount Baker became active. They consist of rhyodacite (dated to 199,000 years ago) and basaltic andesite. [12]
The volcanoes with historical eruptions include: Mount Rainier, Glacier Peak, Mount Baker, Mount Hood, Lassen Peak, and Mount Shasta. Renewed volcanic activity in the Cascade Arc, such as the 1980 eruption of Mount St. Helens, has offered a great deal of evidence about the structure of the Cascade Arc. One effect of the 1980 eruption was a ...
A part of the large eruptions that occurred in southwest Japan to 13 to 15 Ma. [34] Yellowstone Caldera—Lava Creek Tuff: 0.639: Yellowstone hotspot: 1,000 Last large eruption in the Yellowstone National Park area estimated energy yield 875,000 megatons of tnt [39] [9] [10] Awasa Caldera: 1.09 Main Ethiopian Rift: 1,000 [40] Cerro Galán: 2.2
Formation of the caldera about 1.149 [3] million years ago was accompanied by the largest eruption in the history of the Mount Baker volcanic field. [4] The eruption was subglacial, blasting upward through the continental ice sheet. [1] Over 124 km 3 [5] (29.7 cubic miles) of rhyodacite magma erupted from a shallow magma chamber in an ultra ...

A basaltic lava flow traveled down the Sulphur Creek valley and across the Baker River valley; this is the most recent lava flow at Mount Baker. [2] [3] Future eruptions from Schriebers Meadow Cone are unlikely to occur as it is considered a short-lived feature. [2]
