Red circles represent all seismicity and blue circles represent earthquakes as part of earthquake swarms. The size of the circles is scaled to the magnitude of the earthquake. The 630,000 year old Yellowstone caldera is shown as a bold black line within Yellowstone National Park. Mapped faults are shown as light gray lines.

This video shows a rockfall and subsequent explosion that occurred at 7:03 a.m. HST today within the "Overlook crater" at the summit of Kīlauea. This collapse was followed by a smaller rockfall at 7:07 a.m. (not shown in video).

Geneticist, Kylle Roy, extracts DNA from samples to detect Ceratocystis, a fungal pathogen that causes Rapid Ohia Death. Samples have been acquired using aerial spore traps, by collecting wood shavings from ohia trees, or by collecting frass (excrement) of wood-boring beetles.
