Hawaii Five-O Wiki

Kai e'e (Tidal Wave) is the 15th episode of the first season in the remake version of Hawaii Five-0.


Five-0 must find the missing head of the Tsunami Warning Center just as the island is about to be assaulted by a major tsunami.


Life for citizens on the island of Hawaii takes a turn when a tsunami warning alert is sounded, forcing everyone to evacuate.

As this happens, the Hawaii Five-0 team investigate the disappearance of Dr. Norman Russell, the head of the Tsunami Warning Center.

Steve later comes to the conclusion that the supposed tsunami does not actually exist with his theory being proven true. He and Danny later find the hacker, Tanya who organized the fake code.

The team soon discover that Sam Hale, a Commander with the Coast Guard is the one responsible for arranging everything as Hale is planning on breaking into the empty precinct where the $28 million is held.

With Chin Ho Kelly and Kono Kalakaua, the team head to the precinct which is located in the same area as H50's Headquarters and they successfully arrest Hale, knowing that their theft of the $10 million to save Chin will be noticed when they audit the money that Hale attempted to steal.

Steve later learns from Governor Pat Jameson that all $28 million was recovered, which leaves the team greatly disturbed since they do not know how the $10 million they stole was returned.

  • The GOES-11 is a real National Oceanic and Atmospheric Administration (NOAA) satellite. GOES stands for Geostationary Operational Environmental Satellite. It was launched into space in 2000, and remained operational for the west coast of the United States until it was decommissioned and replaced by GOES-15 on December 6, 2011, a year after this episode aired. GOES-11 was put into place to replace the older GOES-10, which was 6 years past its recommended use time. GOES-11 was also over 1 year beyond its use time by the time it was launched, as it lacked the instruments put on GOES-12, which was launched prior to it.
