Are you in the ‘extreme tsunami’ zone? Evacuation plans for an extreme tsunami like the one that Japan experienced in 2011 are much different the current tsunami zones in place today. The City’s Department of Emergency Awareness (DEM) recently released a second set of ‘extreme tsunami’ zone maps. These maps represent an unlikely worst-case scenario and do not replace the current, standard tsunami evacuation maps. Rather, they add a second evacuation zone for a worst case, extreme, once in a thousand years tsunami event.

Evidence of an extreme tsunami event became evident when a sinkhole at Poipu, Kauai was discovered more than 100 yards from the shoreline and about 24 feet above sea level. Newly released scientific and geological information suggests that sometime in the past 500 years, a massive 9.0 earthquake in the eastern Aleutian Trench may have generated a tsunami that far exceeded the inundations known to have occurred during tsunami events throughout recorded history in Hawaii. An event of this magnitude, referred to as an Extreme Tsunami, may occur once every thousand years.

The new tsunami evacuation zone maps show both zones: the current tsunami zone and the NEW ‘extreme tsunami’ zone.
