“…While our study focuses on megaflooding, any event that can cause repeated, regionally synchronous boulder deposition (i.e., earthquake‐triggered landslides, seasonal flash flooding, etc., Dewey et al., 2021) could have similar geomorphic impacts. For example, large earthquakes can trigger landslides that deposit boulders synchronously and regionally in patterns unrelated to stream power (e.g., Devi & Bora, 2016; Meunier et al., 2007; Nowicki Jessee et al., 2018; Parkash, 2013). Earthquakes that recur in similar locations (i.e., on the same faults) could cause region‐wide, repeated boulder deposition that could produce results similar to ours.…”
