Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km^2 study area. These stations are equipped with rain gauges, laser distance meters, and data loggers to record rainfall and stage data (Kean, et al., 2020). This data release includes videos of debris-flows and floods captured by high-definition cameras placed at three different locations, associated with the monitoring stations, along the study area at Chalk Cliffs during 2016. Near the Upper Station (Station 1) there are two cameras, one located at the bridge cross section at the channel (Bridge Camera) and another on the opposite side of the basin with a broad view of the channel (Wide-angle Camera). The third camera (Middle Camera) is located near Station 2. The attached figure \"station_and_camera_locations.png\" provides an overview figure with the location of the three cameras and three stations along the channel. The videos and their audio are used to record information on flow type and velocity of debris flows. They can also be used to interpret how the flow characteristics, such as sediment concentration, vary with time to compare to seismic observations. \nVideo recording for all cameras is triggered using a rainfall threshold, derived from rainfall measurements from the rain gauges (Michel et al., 2019). The complete videos for all the cameras are downloaded manually during site visits. More detailed information about the cameras and settings used can be found in the metadata file under \u201cProcess steps\u201d in \u201cData quality information.\u201d \nDuring 2016, several debris flows and floods were captured by the three cameras. The videos can currently be viewed in the individual \u2018Child item\u2019 pages accessible below. The \u2018Child item\u2019 pages contain either flood or debris flow video files for each camera described above.  \nThe following citations relate to reports that provide background information for this data release:  \nMichel, A., Kean, J.W., Smith, J.B., Allstadt, K.E., Coe, J.A.
