A Valentine's Day 2017 view of Kīlauea Volcano's summit lava lake, here the surface of the lake is about 21 m (69 ft) below the vent rim. The lake diameter is about 255 m or 840 ft. Careful tracking of the amount of ash emitted by lake processes suggest an important new insight into the supply of magma to Kīlauea's summit. USGS Photo.

The surface breakout that started on February 10 remains active on the coastal plain just east of the main episode 61g lava flow field. The flow front, pictured here, advanced to about 300 m (0.2 miles) from the emergency access road in Hawai‘i Volcanoes National Park, but appeared to be stalled this afternoon.

USGS field scientist uses radio telemetry to search for skunks and raccoons tagged with lightweight radio collars. USGS is monitoring skunk and raccoon movements across California's inland marshes to understand how they are using different features of the landscape, like levee roads, to navigate to waterfowl nests.

Chopping several feet of ice to access Black Canyon Creek

A U.S. Geological Survey scientist used a custom-built, high-speed camera to remotely measure the temperature of spattering lava on the surface of Kīlauea Volcano's summit lava lake (background). This particular experiment, conducted from the Jaggar Museum overlook in Hawai‘i Volcanoes National Park on December 10, 2016, was part of a NASA-funded research project.
