Lahar Evacuation Drill
During the March 21, 2024 lahar evacuation drills, thousands of students walked to the Washington State Fairgrounds in Puyallup, Washington to practice evacuating from a lahar generated by Mount Rainier. A lahar, or volcanic mudflow, could reach this area in about 3 hours.

Kīlauea summit eruption in Halema‘uma‘u - June 7, 2023
A summit eruption of Kīlauea volcano, within Halemaʻumaʻu crater, began at approximately 4:44 a.m. on June 7, 2023. Lava is flowing on the crater floor and there are several active vent sources. The eruption at Kīlauea’s summit is occurring within a closed area of Hawai'i Volcanoes National Park and high levels of volcanic gas are the primary hazard of concern.

Smallmouth Bass
Smallmouth Bass are good indicators of methylmercury exposure to humans and wildlife because they are a common, popular sport fish and eat a variety of food during their lifetime. Juvenile Smallmouth Bass – smaller than 150mm in length - eat zooplankton, or microscopic animals.

Automated radio telemetry base station
A major advancement in the use of radio telemetry has been the development of automated radio tracking systems (ARTS) which allow animal movements to be tracked continuously. A new ARTS approach is the use of a network of simple radio receivers (nodes) that collect radio signal strength (RSS) values from animal-borne radio transmitters.

A geologists makes observations at Kilauea
Clear weather allowed HVO geologists to make observations and take measurements of the water pond at Kīlauea's summit. No major changes were observed, and the water level continues to slowly rise. Note the former HVO observation tower can be seen above the geologist's helmet.

Unoccupied Aircraft System with water sampler
The sampling mechanism (on blue tarp) is prepared and the Unoccupied Aircraft System (UAS) is inspected just before take off to collect water from the Halema‘uma‘u crater lake. Brightly colored flagging tape tied to a cable attached to the UAS indicated depth as the sampling tool was lowered into the water.
