The blue line shows the radial tilt at Uwekahuna station (UWE), on the western rim of Kīlauea's caldera. The green line is radial tilt at Pu‘u ‘Ō‘ō (POO), north of Pu‘u ‘Ō‘ō cone. These are recorded by continuously operating electronic tiltmeters. Positive changes often indicate inflation of the magma storage areas beneath the caldera or Pu‘u ‘Ō‘ō, but may also result from

Depth of earthquakes during the past month at Kīlauea. Circle-size represents magnitude, and color indicates depth.

Number of earthquakes per day during the past month (blue bars). The red line is the cumulative moment (energy) release. 

Depth of earthquakes (circles) during the past month. Circle-size represents magnitude, and color indicates depth.

A coral reef in the Turks and Caicos Islands dominated by the weedy coral species, Porites astreoides. The relative dominance of this taxa has increased throughout the western Atlantic.

This is remote capture image of a Yosemite toad seen crossing beneath "toad road" structure built atop a forest road in the Sierra National Forest. Reseachers are exploring tools, such as this elevated road structure, or "toad road," to reduce vehicle strikes to this threatened species.

Map showing ice cover in the Yellowstone region. Light shaded areas bounded by black and red lines indicate areas covered during the Pinedale (about 20,000-15,000 years ago) and Bull Lake (about 150,000 years ago) glaciations, respectively. Blue lines are contours in thousands of feet on the maximum reconstructed Pinedale glacier surface. The circled numbers schematically

Apparatus used to test the sensitivity of eels to low-voltage pulsed DC electric fields. Knowledge of sensitivity of eels to electric fields enables development of behavioral barriers that use electricity to guide eels away from turbine intakes.

Prototype design of an airlift developed at CAFL to transport downstream migrant eels through a bypass pipe and away from turbine intakes. The airlift design passes eels as well as a conventional siphon or gravity pipe.

Radio-tagged silver phase American Eels being released for a CAFRL telemetry study of downstream passage of eels at hydroelectric dams on the Shetucket River, Connecticut.

Left: Prototype ABS plastic eel climbing ramp under development and testing at CAFRL. New substrate design allows for passage of a wider size range of eels with less need for precise flow regulation. Right: juvenile eel climbing wetted ABS plastic substrate.
