A tsunami was caused by coastal subsidence associated with reactivation of the Hilina Slump, triggered by the earthquake. At Kapapala the land subsided by as much as 2 m and formerly dry land was flooded to a depth of 1.5 m. [10] The tsunami on the Kaʻū and Puna coasts caused major destruction at Honu‘apo, Keauhou and Punaluʻu. The ...
The tsunami is known as the Hawaii April Fools' Day Tsunami because it happened on 1 April and many people thought it was an April Fool's Day prank. The result was the creation of a tsunami warning system known as the Pacific Tsunami Warning Center (PTWC), established in 1949 for the countries of Oceania. 1946: Nankai, Japan: 1946 Nankai earthquake
Significant damage occurred in the southern part of the Big Island totalling $4–4.1 million, and it also triggered a small brief eruption of Kilauea volcano. The event generated a large tsunami that was as high as 47 feet (14 m) on Hawaii'i island and was detected in Alaska, California, Japan, Okinawa, Samoa, and on Johnston and Wake Islands.
The earthquake, which didn't cause a tsunami and which the U.S. Geological Survey initially reported as magnitude 6.3, was centered on Mauna Loa's southern flank at a depth of 23 miles (37 ...
Giant landslides and collapses of ocean island volcanoes were first described in 1964 in Hawaii and are now known to happen in almost every ocean basin. [1] As volcanoes grow in size they eventually become unstable and collapse, generating landslides [2] and collapses such as the failure of Mount St. Helens in 1980 [3] and many others. [4]

The main tsunami traveled across the Pacific Ocean and devastated Hilo, Hawaii, where waves as high as 10.7 metres (35 ft) were recorded over 10,000 kilometres (6,200 mi) from the epicenter. The death toll and monetary losses arising from this widespread disaster are not certain. [ 8 ]
The tsunami caused two deaths in Kamchatka and one in Hawaii. The earthquake happened 26 years before the U.S. had the capability to issue tsunami warnings, but Thomas Jaggar, the director of the Hawaiian Volcano Observatory, tried to warn the Hilo harbormaster about the possibility of a tsunami. His warning was not taken seriously and one ...
