Caption:Kirsten Nicolaysen, Whitman College and Islands of Four Mountains Project leader, leans on a recently emplaced lava block carried down the flank of Cleveland volcano in a block and ash flow. The deposit probably formed when a lava flow high on the flank of the volcano collapsed and tumbled down the side of the volcano, all the way to the sea.

Caption:AVO's John Lyons photographed this small rockfall event at Cleveland in late July 2014 during the field campaign to install the monitoring network. Notice the light-colored trail of dust rising above the path of volcanic debris that tumbled down the east flank of the volcano. We suspect these rockfalls come from steep, unstable piles of debris ejected during explosions earlier in the year. Folks in the field could hear the rocks rumble down the slope. Below the photograph are two ways of seeing rockfalls using seismic data from the new station CLES at the southeast base of the volcano. On top is the seismic waveform - here spanning 1 minute and 30 seconds from left to right - showing the typical spindle-shaped, emerging and slowly diminishing ground shaking signal seen during rockfalls in many settings. Below that is the same information in the frequency domain: warmer colors show higher amounts of energy at different frequencies contained within the waveform. Rockfalls show a mixture of high and low frequency content. Knowing this, we can detect these events from our offices far from the volcano.
