IIRC, one of the Hawaiian Islands is cracking and is expected to do the same thing in the Pacific. I dont know if the 'wave' is to be aimed at the US or not.
Scientists speculate that the wave generated by the Nu'uanu slide off Oahu that hit the California coast was in excess of 150 feet. It was aimed directly at CA.
Any future slide will probably originate off the southeast coast of the Big Island - Chile & Peru will be the lucky recipients.
Debris from enormous landslides off Oahu and Molokai extends hundreds of kilometers
