What is the danger of Crater Lake?

Landslides or rock falls could be triggered within Crater Lake caldera by earthquakes or by renewed volcanic activity. Failure of part of the caldera wall could cause a rapidly moving material to enter the lake, which may produce one or more large waves that could travel rapidly across Crater Lake and impact its shore.
