Tsunami
A tsunami is a series of waves caused by the displacement of a large volume of water, most likely because of an earthquake or other Coastal Subduction Zone (CSZ) event.
“20 Meters in 20 Minutes” means that after the shaking stops from a CSZ event, there will be approximately 20 minutes to evacuate to high ground prior to the arrival of the first tsunami waves.
