WThis is a list of earthquakes in 1964. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. Alaska had the largest event of the year both in terms of magnitude and death toll. In March a great magnitude 9.2 earthquake struck the southern part of the state. This was the largest earthquake in United States' history and currently as of 2017 ranks as 3rd largest globally. The quake and subsequent tsunami resulted in 139 deaths in total. In spite of such a large event there were only 11 other magnitude 7.0 + events which is below normal. Japan, Taiwan and Mexico had earthquakes which resulted in a number of deaths. Indonesia and Papua New Guinea experienced high activity this year with a cluster of magnitude 6.0 + events hitting throughout the year.
WThe 1964 Manyas earthquake happened on October 6 on the southern coast of Marmara Sea near the city of Karacabey in Bursa Province, Turkey. The shock had a moment magnitude of 6.8 and a maximum Mercalli intensity of IX (Violent). Around $5 million in damage was caused, with 19–73 killed and 100–239 injured.
WThe 1964 Rosais earthquake was a series of seismic swarms occurring in February 1964, leading to two major earthquakes on the 15 and 21 of February, resulting in the destruction of most of the habitable dwellings on the western part of the island of São Jorge, in the archipelago of the Azores. The event resulted in the evacuation of approximately 5,000 residents from that island to Terceira, Pico and Faial.
WThe 1964 Alaskan earthquake, also known as the Great Alaskan earthquake and Good Friday earthquake, occurred at 5:36 PM AKST on Good Friday, March 27. Across south-central Alaska, ground fissures, collapsing structures, and tsunamis resulting from the earthquake caused about 131 deaths.
WThe 1964 Baihe earthquake, also known as the Great Baihe earthquake, measured 6.3 local magnitude, and occurred at 20:04 CST (UTC+8) on 18 January in Baihe Township of Tainan County, Taiwan. The hypocenter of the earthquake was 20 kilometers deep. The earthquake killed 106 people, destroyed 10,924 buildings, and caused a great fire in Chiayi City. It was the sixth deadliest earthquake in 20th century Taiwan, and the third deadliest post-World War II, after the 921 earthquake and the 2016 Taiwan earthquake.
WThe 1964 Guerrero earthquake occurred on July 6 at 01:22 local time in Guerrero, Mexico. The magnitude of this earthquake was given as Ms 7.4, or ML 7.2.
WThe 1964 Niigata earthquake struck at 13:01 local time on 16 June with a magnitude of either 7.5 or 7.6. The epicenter was on the continental shelf off the northwest coast of Honshu, Japan in Niigata Prefecture, about 50 kilometres (31 mi) north of the city of Niigata. The earthquake caused liquefaction over large parts of the city.
