Two earthquakes occurred in the morning on Hawaii Island. The first earthquake (3 hours 36 minutes local time, 5.1 Ms, epicenter near the Kilauea crater) awakened the entire population of the island. The second earthquake (4 hours 48 minutes local time, 7.2 Ms, off the southeast coast) caused damage (IX) at Hilo and damage (VIII) at Hawaii Volcanoes National Park. In many places houses were severely damaged, roads were breached and became unusable due to landslides; electric power lines were broken. Maximum subsidence 3.5 meters along the southeast coast. Maximum width of ground cracks 1 meter in the park. There was a brief eruption of the Kilauea Volcano. The second earthquake generated a locally damaging submarine landslide tsunami that was recorded at tide gauge stations in Alaska, California, Galapagos Islands, Peru, and Chile.

The tsunami was generated by a magnitude 9.0 (Mw) earthquake on Kamchatka where it caused severe damage. The tsunami then struck Midway (3,000 kilometers away), the Hawaiian Islands (5,200 kilometers away), and other areas in the Pacific.

The magnitude 6.5 earthquake killed 7 and caused 12.5 million in property damage.

A magnitude 8.1 earthquake occurred in the southern Kurils and on northern Hokkaido on Tuesday, October 5, 1994, (October 4 at 13:23 GMT). It was a sudden event, without any short- term precursors or foreshocks. The earthquake epicenter was located 80 km east southeast of Shikotan Island. At Kuzhno-Kurilsk, Kunsashir Island, tsunami heights ranged from 2.5-3.0 m. In the older part of town (fronted by a gentle beach) all houses were damaged by the wave that penetrated 200-500 m inland.

On November 3, 1994, at 7:10pm local time, a large tsunami generated by a massive landslide in the submerged Skagway River delta occurred near Skagway, Alaska. This event resulted in one fatality and approximately $25 million of damage, leaving several harbor structures damaged or destroyed.

The tsunami generated by a magnitude 7.9 (Mw) earthquake destroyed 700 boats and 59 houses for a total of $800 million in property damage in Japan (1983 dollars). One hundred and four people drowned in Japan and three drowned in Korea.

On July 12, 1993, a magnitude 7.6 Ms (7.7 Mw) (HRV) earthquake at 13:17 UT in the Sea of Japan near Hokkaido caused a back-arc tsunami that caused damage in all of the countries bordering the Sea of Japan. The earthquake had a rupture length of 150 kilometers, a movement of 2.5 meters and a dip to the east of 24 degrees. The tsunami was 32 meters high on Okishuri, Island, where the most destruction occurred. The whole island subsided by 5-80 centimeters.

The March 11 earthquake generated a devastating tsunami that was observed all over the Pacific and caused tremendous devastation locally, including an accident at the Fukushima Daiichi Nuclear Power Plant.

5 kilometers southwest of Newport Beach. Seriously affected area: 1,200 square kilometers. Damage: $40 million. Schools were among the buildings most severely damaged because they were not designed to resist shaking. In addition to the damage to the schools at Long Beach, the schools at Buena Park were badly damaged. There was also considerable damage to schools at Lomita, and two schools were damaged at Redondo Beach. Great loss of life would have occurred if the shock had taken place during school hours. Unlike the 1906 San Francisco earthquake, the loss due to fire in the 1933 earthquake was almost negligible.

Epicenter: 34.0 degrees N, 118.1 degrees W. Magnitude: 5.9. Damage: $358 million. Eight deaths. The fault which ruptured was located about 11 kilometers below the surface, and 20 kilometers east of downtown Los Angeles. The fault was an extension of the previously identified Whittier Fault. Severe damage was confined mainly to communities of Los Angeles and near the epicenter.
