The 2018 Hilina Slump Collapse was caused by an underwater landslide caused by a large earthquake on the Puna side of the island. It began May 3. There was an 8.0 earthquake in Honolulu which triggered a former extinct volcano eruption. The eruption caused mass property destruction and led to an undersea landslide on Oahu as well.  


Event[]

A large localized tsunami hit the Puna coast within 15 minutes, devastating the shoreline. The tsunami swept around the island hitting the Kona coast. Substantial wave heights were recorded in Kona causing flooding of the main Alii'i drive, as well as waves that passed the tsunami warning signs.

Honolulu faced millions of dollars in damage although wave heights were relatively lower, and the tsunami warning signs were able to save many lives.

West Coast cities faced significant damage. Major west coast cities such as parts of Los Angeles and San Diego.
