On July 10, 1958, at 06:15:59 UTC, a M 7.8 earthquake occurred in Southeast Alaska. At least 8 separate tsunamis, generated by submarine and subaerial landslides and ice falls, followed the earthquake. The epicenter was located on the northern coast of Cross Sound near Palma Bay. A local submarine slump off Khantaak Island in Yakutat Bay caused 3 deaths and wrecked a boat. Lituya Bay, the site of repeated huge local tsunamis, experienced a massive landslide which generated a surge of water reaching 525 meters in height -- 400 feet higher than the Empire State Building. Property damages, primarily from lost boats, exceeded $100,000.

On Sunday, August 10th, 2025, at 13:26 UTC, a landslide occurred in Tracy Arm, Alaska, about 80 miles (130 km) south-southeast of Juneau. The landslide generated a tsunami in the fjord where a runup height reached an estimated 470 m on the opposite shore and was also recorded far from the source on a NOAA coastal tide gauge in Juneau. The National Tsunami Warning Center reported that the maximum tsunami wave height at the gauge was 36 cm (approximately 14 in) above the tide, and that the waves continued for hours.

On August 16, 1976, at 16:11:07 UTC, a magnitude (Mw) 8.0 earthquake shook Mindanao Island in the Philippines. It caused a destructive tsunami in the Celebes Sea that devastated settlements along the coast of Moro Gulf on Mindanao Island, Zamboanga Peninsula and Sulu Islands. As a result of the earthquake and tsunami 4,000 to 8,000 persons were killed or missing, 10,000 were injured, and 90,000 were left homeless. 85% of the casualties may be attributed to the tsunami.

The Hunga-Tonga Hunga-Ha'apai volcano, located 60 km northwest of Tongatapu, Tonga, began erupting at 0407 UTC on 15 January 2022 with a massive explosive eruption at 0414 UTC from seismic data. The eruption triggered a tsunami that caused damage locally, regionally, and across the Pacific. The local tsunami killed three people and caused major destruction to many low-lying coastal communities on Tongatapu, ‘Eua and the Ha'apai Group of Tonga; runups up to 15 m and 500 m inundation were reported for Mango Island by the Tonga Geological Services (TGS). Elsewhere, waves up to 2 m in amplitude were reported by the Pacific Tsunami Warning Center (PTWC). Many countries experienced waves greater than 0.3 m in amplitude and damaging waves struck harbours and coasts in New Zealand, Rarotonga, Hawaii and the US west Coast, and as far away as Peru (additionally, two deaths occurred), Chile in the eastern Pacific, and Japan in the northwestern Pacific.

On November 14, 1994 at 19:15:30 UTC, a magnitude 7.1 Mw earthquake struck in the Verde Island Passage between Luzon and Mindoro Islands, Philippine Islands. A local tsunami contributed to extensive damage in the Calapan and Puerto Galera areas. More than 797 houses destroyed and 3,288 damaged on Mindoro. Seven houses destroyed at Batangas, Luzon. The earthquake and subsequent tsunami contributed to injuries or death of more than 300 people. Liquefaction, sand boils and surface faulting occurred in the epicentral area. NOTE: Images in this collection were taken by an International Tsunami Survey Team (ITST).

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.

The shield volcano consists of more than 20 eruptive centers over a 20 x 30 km area that also includes Japan's first national park. Sixty-nine eruptions have been documented since 742 A.D. Kirishima is one of Japan's 31 active volcanoes, and has erupted 19 times since 1700.
