Detailed Description
USGS marine technician Pete Dal Ferro, from the Pacific Coastal and Marine Science Center, prepares to deploy the bubbler system from an inflatable vessel offshore of Santa Cruz, California. The compressed air was stored in the large white cylinder, and the yellow air hose was connected to a garden soaker hose wrapped around a weight. After the weight was lowered about 35 meters into the water, the bubbler was turned on and a stream of bubbles rose in the water column, simulating a seafloor seep.

An earthquake can trigger a landslide along the ocean floor, which can then set off a tsunami. Without modern, high-resolution imaging of the seafloor, many historical slides and threats from future slides remain undetected.
