In 2004, unidentified marine fossils were found

In 2004, unidentified marine fossils were found at the base of the volcano 6 km (4 mi) inshore. A research team led by University of Hawaii's Gary McMurtry and Dave Tappin of the British Geological Survey in Nottingham found that the fossils had been deposited by a massive tsunami, 61 m (200 ft) above the current sea level.[5] The team dated the fossils and nearby volcanic rock at about 120,000 years old. Based on the rate of Kohala's subsidence over the past 475,000 years, it was estimated that the fossils were deposited at a height of about 500 m (1,640 ft), well out of reach of storms and far above the normal sea level at the time.[6] The timing corresponds with the last great landslide of nearby Mauna Loa. Researchers hypothesize that the underwater landslide from the nearby volcano triggered a gigantic tsunami, which swept up coral and other small marine organisms, depositing them on the western face of Kohala. Mauna Loa, an active volcano, has since repaired its flank. Dave Tappin, a marine geologist with the British Geological Survey believes that a "future collapse on this volcano, with the potential for mega-tsunami generation, is almost certain."[6]
