About 3 million years ago, the southern limit of active volcanoes in the Cascades corresponded to the Yana Volcanic Center 19 mi (30 km) to the south of Lassen Peak, but currently the southern edge of the Lassen Volcanic National Park now marks the same border, indicating that the Cascade Arc's southern end migrates at a rate of 0.4 to 1 in (1. ...
Lassen Volcanic National Park is one of the few areas in the world where all four types of volcanoes can be found: plug dome, shield, cinder cone, and stratovolcano. [ 4 ] The source of heat for the volcanism in the Lassen area is subduction of the Gorda Plate diving below the North American Plate off the Northern California coast. [ 5 ]
Over time, the volcano became dilapidated from extensive erosion and hydrothermal alteration, [6] and was eroded by creeks and glaciers. Later activity built more than thirty other cones known as the Lassen Domes. Today the most active volcano in the area is Lassen Peak. Other smaller craters younger than 50,000 years are also active.

Lassen Volcanic National Park has a lot in common with its famous sister parks, but far fewer visitors.

Defying initial fire suppression efforts, the Park Fire grew rapidly over the following days, burning into the Ishi Wilderness and the Lassen National Forest. Thousands of people in foothill communities evacuated, Lassen Volcanic National Park closed to the public, and hundreds of buildings were destroyed. The fire burned a total of 429,603 ...
The threat assessment is not a list of which volcanoes are most likely to erupt or a ranking of those that are most active; rather, it's defined as a combination of a volcano's potential threat ...
Cinder Cone is in Lassen Volcanic National Park. Cinder Cone is a 700 ft (210 m)-high volcanic cone of loose scoria. [5] The youngest mafic volcano in the Lassen volcanic center, [6] it is surrounded by unvegetated block lava and has concentric craters at its summit, [5] which have diameters of 1,050 ft (320 m) and 590 ft (180 m).
