Eruption information
This Holocene volcano erupted in the year 2220 ± 300 years B.C. When Dotsero blew, it created small scoria cones that were constructed along a NNE-SSW line on either side of the maar. The eruption date is based upon radiocarbon dating of wood found underneath some of the scoria. It is one of the youngest eruptions in the continental U.S. and it produced an explosion crater, a lahar, and a 3-kilometer (1.9 mi) long lava flow.
Volcanoes that have erupted in the past 10,000 years are more likely to become active again.
Interstate 70 cuts across the lava flow.
