The event generated a large tsunami that was as high as 47 feet (14 m) on Hawai'i island and was detected in Alaska, California, Japan, Okinawa, Samoa, and on Johnston and Wake Islands. Significant changes to the shorelines along the southern coast of the Big Island with subsidence of 12 feet (3.7 m) was observed, causing some areas to be permanently submerged. The source of the event was the Hilina Slump, which was also responsible for the more powerful 1868 Hawaii earthquake and tsunami.
