The United States Geological Survey National Volcanic Threat Assessment is a report containing a ranked list of active volcanoes in the United States posing hazardous risks to the American population. [1] The report was published by the United States Geological Survey in 2005 [2] and revised in 2018. [3]
Mount Rainier [a] (/ r eɪ ˈ n ɪər / ray-NEER), also known as Tahoma, is a large active stratovolcano in the Cascade Range of the Pacific Northwest in the United States. The mountain is located in Mount Rainier National Park about 59 miles (95 km) south-southeast of Seattle. [9]
There are around 200 volcanoes in Texas that have been extinct for millions of years, making them unlikely to erupt again, because the volcano no longer has a magma supply.
The volcano has been relatively quiet during the 21st century, with only a handful of small magnitude earthquakes and no demonstrable ground deformation. Although geophysically quiet, periodic geochemical surveys indicate that volcanic gas emanates from a fumarole at the summit of Mount Shasta from a deep-seated reservoir of partly molten rock.
The world's largest active volcano has erupted in Hawaii for the first time in nearly four decades, officials said.. Mauna Loa erupted at 11:30 p.m. local time Sunday (4:30 a.m. ET Monday), the U ...
World map of active volcanoes and plate boundaries Kīlauea's lava entering the sea Lava flows at Holuhraun, Iceland, September 2014. An active volcano is a volcano that has erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago), is currently erupting, or has the potential to erupt in the future.

The lake partly fills a 2,148-foot-deep (655 m) caldera [3] that was formed around 7,700 (± 150) years ago [4] by the collapse of the volcano Mount Mazama. No rivers flow into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 150 years. [ 5 ]
