are the sutter buttes volcanic?
153579
The Sutter Buttes are remnants of a volcano that was active approximately 1.6 to 1.4 million years ago during the Pleistocene Epoch. The central core of the Buttes is characterized by lava domes—piles of viscous lava that erupted onto the surface and were built higher with each successive layer.

So magma is always present beneath a dormant volcano, and has solidified to solid rock under an extinct volcano. The magma that is there is part of the continuous stream of molten rock being forced upward, which never really ceases so long as the volcano is not extinct.

Mount Baker is also an active volcano. While the most recent eruption of new lava from Mount Baker occurred 6,700 years ago, other hazardous activity has caused impacts on the volcano's slopes and downstream.

Rainier is one of 16 Decade Volcanoes in the world (the designation for the ones considered most hazardous) and the only Decade Volcano in the U.S. other than Mauna Loa in Hawaii. It's the tallest peak in the Cascade Range, which is why it's so visible from the Seattle area.

All volcanic eruptions pass through the crater at the volcanic summit. One of the reasons volcanic eruptions are so deadly is that there is no way to predict an where an eruption will occur in the near future. ... Volcanoes are entirely detrimental to the planet and human civilization, offering no benefits to humankind.

It last erupted in 1894-95, when small summit explosions were reported by observers in Seattle and Tacoma. Mount Rainier's next eruption might be of similar or larger size and could produce volcanic ash, lava flows, and avalanches of intensely hot rock and volcanic gases, called "pyroclastic flows."

Subduction volcano. Stratovolcanoes tend to form at subduction zones, or convergent plate margins, where an oceanic plate slides beneath a continental plate and contributes to the rise of magma to the surface. ... Volcanoes are not generally found at strike-slip zones, where two plates slide laterally past each other.

Navajo Mountain and the Henry Mountains are all examples of volcanoes that never quite made the grade about 20 to 30 million years ago when the magma was first injected.

Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption. The most recent lava flow occurred about 70,000 years ago, while a violent eruption excavated the West Thumb of Lake Yellowstone around 150,000 years ago.

Some of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.

Crater Lake partially fills a type of volcanic depression called a caldera that formed by the collapse of a 3,700 m (12,000 ft) volcano known as Mount Mazama during an enormous eruption approximately 7,700 years ago. The climactic (caldera-forming) eruption of Mount Mazama changed the landscape all around the volcano.

IS THERE A VOLCANO IN WAIKIKI? A volcano commonly known as Diamond Head grandly presides over Waikiki, the world-famous mecca for tourists in the state capital of Honolulu. It's one of several volcanic craters on Oahu that scientists believe were formed between 40,000 and 500,000 years ago. ... No Oahu volcano is active.

The Yuba City area is located 40 miles north of Sacramento and situated in the Sacramento Valley. It is home to the Sutter Buttes, the smallest mountain range in the world.

Mount Adams, known by some Native American tribes as Pahto or Klickitat, is a potentially active stratovolcano in the Cascade Range. Although Adams has not erupted in more than 1,000 years, it is not considered extinct. It is the second-highest mountain in Washington, after Mount Rainier.

In Mount St. Helens' case, an oceanic plate called Juan de Fuca slips under the North American plate, creating the Cascadia subduction zone. A continental arc brews adjacent to the subduction zone, where high pressures and hot temperatures force molten rock to the surface. The result is a chain of volcanoes.

Old Faithful is one of Yellowstone's most popular geological features. ... Scientists at the Yellowstone Volcano Observatory at the University of Utah are constantly monitoring the underground supervolcano for ground movements and earthquake activity.
