Which increasing risk to alpine communities results when permafrost thaw amplifies seismic ground motion?

💡 Explanation

Mountain permafrost thawing destabilizes slopes, amplifying earthquake-induced shaking via the topographic amplification mechanism; because slopes fail easier, this increases the likelihood of glacial lake outburst floods from collapsing ice/rock deposits. Therefore increased flood risk, rather than the other stable-earth outcomes is the response.
