Instruments designed to record earthquakes revealed information about debris-flow speed, the width of the flow and the size of boulders carried by the January 2017 mudslide in Montecito, California, and the location of the event, suggesting that the current generation of seismometers in the field could be used to provide an early warning of an incoming debris flow to residents in mudslide-prone areas.
