Tiltmeter data are available from PBO instruments in four separate arrays: two in Alaska on Akutan and Unimak islands, one on Mt. St. Helens, and one in Yellowstone National Park.
Raw (Level 0) tiltmeter data consist of ASCII files containing X/Y tilt and instrument temperature. Sampling rates are either 1 Hz or 1 sample-per-minute, depending on the station. There are no processed tiltmeter data products because raw tilt data can be directly used in modeling or to monitor deformation.
