A myriad of plants can be seen from above in this photograph taken at the Kahuku Unit of Hawai‘i Volcanoes National Park. Acquired in 2009, the Kahuku Unit of Hawai‘i Volcanoes National Park has been an area that multiple USGS PIERC researchers study in, including Dr. Steven C.

The "spider" (a self-contained portable instrument package) was engineered and deployed during the 2004-2008 eruption of Mount St. Helens to detect and triangulate shallow earthquakes, monitor local ground deformation and uplift, detect lightning that might indicate an ash eruption and low frequency sound from explosions.

HVO geologists noted persistent spattering in the northeast corner of the lava lake within the Overlook vent during their night-time observations. The view of the lake surface was fairly good because of fume in the area of the Overlook was "thin" at the time.

Incandescence from the lava lake surface (out of view) reflects an awesome glow on the gas plume rising from the lake surface.

Christmas tree worms have made their home on a brain coral. Tropical corals reefs are complex ecosystems, but are rapidly being lost to bleaching and disease, linked to increasing water temperatures.
