View of the Carrizozo lava flow from space.
The 75-km- (50-mi-) long Carrizozo lava flow is located in south-central New Mexico in the Tularose Basin. Eruption began approximately 5,000 years ago, and after two to three decades at a relatively low effusion rate, 4.3 km

) of land. All of the lava originated from a vent, Little Black Peak, on the northern end, which is visible today as a 27-m (88-ft) tall cinder cone that rises above the flow. The vent lies within a zone of known crustal weakness, the Capitan lineament, where magmas are able to rise through the crust and erupt on the surface. The lava flow is one of the longest known that has erupted on Earth in the past 10,000 years. It achieved its great length by flowing in insulated lava tubes. Carrizozo Malpais is the local name, which roughly translates to “bad footing” in Spanish, and describes the difficulty of traversing the area.

2018 update to the U.S. Geological Survey national volcanic threat assessment
2018 update to the U.S. Geological Survey national volcanic threat assessment
When erupting, all volcanoes pose a degree of risk to people and infrastructure, however, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location. Assessing the relative threats posed by U.S. volcanoes identifies which volcanoes warrant the greatest risk-mitigation efforts by the U.S. Geological Survey and its partners...
