Laser Rangefinder Data for Surficial Mass Movements in the Cascades: Mount Rainier 2023
A laser rangefinder was used to record debris flows at Cascades volcanoes and an experimental debris flow flume. Mass movements such as large lahars and smaller seasonal debris flows can occur at volcanoes in the Cascades. A combination of seismic, infrasound, tripwires, and webcams can be used to detect and characterize these flows. A laser rangefinder can be placed on the banks of the drainages and pointed towards the channel as a low power, low bandwidth piece of equipment to confirm increases in flow past the station. This can serve as another piece of evidence for flows and may be able to be incoporated into future alarm systems to improve their accuracy and performance.
A laser rangefinder was deployed for ~2 months in the summer of 2023 at Mount Rainier, co-located with the USGS Cascades Volcano Observatory (CVO) monitoring station TABR (46.80435 N and 121.84948 W), that includes a 3-component broadband seismometer and single infrasound sensor. The instrument was at a slant distance of ~65 m and pointed at 29 degrees from horizontal at the active portion of the channel. The laser rangefinder was a LaserTech TruSense S200 series logged at 1 Hz sampling rate using a Campbell Scientific CR6 digitizer and timing antenna.
