Did you know that plants can help us understand what is happening underground? Studying plants in an area can sometimes provide information about soil conditions, water availability, and water quality.

An ADCP is used to measure streamflow from a bridge near Kelly, Wyoming. Even with smoke making the view hazy, the Tetons never fail to make measuring streamflow in the Gros Ventre a treat.

A colorful sunrise appears over the horizon of a calm ocean offshore of Jensen Beach, Florida. USGS Scientist RC Mickey collects data for location and elevation of sea turtle crawls and associated beach profiles this stretch of coastline.

The emission of volcanic gases, including sulfur dioxide and hydrogen sulfide, is not unusual at the summit of Kīlauea. However, sulfur dioxide gas emission rates are now lower than they have been since before 1983, with about 50 tonnes/day measured at the summit of the volcano on the day of this photo (October 24).

These two plots show summit tilt (ground deformation) and seismicity (earthquake counts) on Kīlauea Volcano between July 15 and August 5, 2018. A regular pattern emerged in which seismicity gradually increased over 1-3 days (bottom), until the caldera floor suddenly dropped several meters (yards) in a matter of seconds.

This aerial view of the western part of Kīlauea Volcano's caldera was taken on August 6, 2018. The down-dropped block is faulted about 120 m (400 feet) below the caldera floor. Many 19th-century lava flows are exposed in the fault scarps. Halema‘uma‘u (not visible) is to the left of this photo.
