Researchers discovered that human alterations to the environment set up these massive waves in the past. Experts caution that modern populations could easily trigger similar disasters again if similar environmental pressures and land use practices occur. The findings highlight the surprising role of human activity in generating extreme natural hazards in freshwater environments.Why it mattersEnv
