Earthquakes; July-August 1977

July and August were somewhat active seismically speaking, compared to previous months of this year. There were seven earthquakes having magnitudes of 6.5 or greater. The largest was a magnitudes of 6.5 or greater. The largest was a magnitude 8.0 earthquake south of Sumbawa Island on August 19 that killed at least 111. The United States experienced a number of earthquakes during this period, but only one, in California, caused some minor damage.

Earthquakes; January-February, 1978

Seismically speaking, 1978 began slowly. The first major earthquake (magnitude 7.0 and above) of the year occurred on February 9 and was centered in the Kermadec Islands region in the South Pacific Ocean. The first destructive earthquake of the year strukc southern Honshu, Japan, on January 14. The magnitude 6.5 earthquake caused considerable damage and loss of life. The United States experienced a number of earthquakes during this reporting period, but only very minor damage and no casualties were reported.

When an earthquake occurs....

When an earthquake occurs, we must be ready at the National Earthquake Information Service (NEIS) in Golden, Colo., to provide information as to its magnitude and epicenter as quickly as possible.This information is given to agencies concerned with disaster relief and to the press. A typical scenario for our operations was the recent Rumanian earthquake of March 4, 1977.

Earthquakes, October-November 1976

October brought two damaging earthquakes to Ecuador and New Guinea. The Ecuador earthquake, although only magnitude 5.5, caused casualties and damage. The new Guinea earthquake, a major quake, caused a loss of life and damage. Two major earthquakes were experienced during November, in eastern Turkey on November 24 and in northern Chile on November 30. The Turkey earthquake was devastating as usual in that area. Other areas of the world experienced strong earthquakes-Iran, China, Solomon Islands, and the Philippine Islands; some caused death and damage. The United States experienced a number of moderate earthquakes, but no signigicant damage sustained.

Earthquakes; May-June 1977

The months of May and June were somewhat quiet seismically speaking. There was only on significant earthquake, a magnitude 7.2 on June 22 in teh Tonga Islands. In teh United States, the two largest earthquakes occurred in California and on Hawaii.

Earthquakes; January-February 1977

There were no major earthquakes (7.0-7.9) during the first 2 months of the year, and no fatalities were reported. Three strong earthquakes occurred- New Guinea, Tadzhik S.S.R, and the Aleutian Islands. The Tadzhik earthquake on January 31 caused considerable damage and possible injuries. The United States experienced a number of earthquakes, but only very minor damage was reported.

Earthquakes, December 1976

The month of December was seismically quiet compared to the previous months of the year. There were no major earthquakes during the month and only one that caused fatalities. On December 8, the Republic of South Africa was struck by an earthquake that caused deaths and damage. The United States experienced number of earthquakes, but only very minor damage was reported. This year ended with 18 earthquakes of magnitudes 7.0 or greater and probably ranks as the world's worst year for earthquake fatalities since 1556 when 830,000 people were killed in China.

Earthquakes: August-September 1976

Destructive earthquakes continued to strike in many parts of the world during this period. The sparsely populated area of the New Hebrides Islands in the southwest Pacific was struck by a major earthquake (one with a magnitude between 7.0 and 7.9). A great earthquake (magnitude 8.0 or above) struck just off the west coast of Mindanao, Philippine Islands, generating a tsunami, killing thousands of people, and causing extensive damage. Three strong earthquakes rocked the Szechwan province of Chian, probably causing loss of life and damage in the epicentral area. The Untied States again did not expereince any destructive earthquakes. The strongest, one of magnitude 5.9, was located in southern Alaska.

Earthquakes June-July 1976

This was a seismically active period, with one great earthquake, four major earthquakes, and several strong shocks worldwide. Many persons were killed and thousands were injured in three separate events-in West Irian (west New Guinea), in Bali, Indonesia, and in northeastern China. A great earthquake (one with a Richter magnitude 8.0 or above) occurred in northeastern China. Major earthquakes (those with Richter magnitudes between 7.0 and 7.9) occurred off the southwest coast of Sumatra, in West Irian (west New Guinea), at the Panama-Colombia border, and in northeastern China. In the United States, a number of States were struck by earthquakes, but no significant damage was reported.

Earthquakes; March-April 1975

There were no major earthquakes (magnitude 7.0-7.9) in March or April; however, there were earthquake fatalities in Chile, Iran, and Venezuela and approximately 35 earthquake-related injuries were reported around the world. In the United States a magnitude 6.0 earthquake struck the Idaho-Utah border region. Damage was estimated at about a million dollars. The shock was felt over a wide area and was the largest to hit the continental Untied States since the San Fernando earthquake of February 1971.

Earthquakes, November-December 1973

A number of significant earthquakes happened during the last 2 months of 1973. Two major earthquakes (magnitude 7.0-7.9) occurred in the New Hebrides Islands, bringing the final major earthquake total for the year to 11, somewhat below the annual average which is 18. One great earthquake (magntidue 8.0 and above) per year is average, but none occurred in 1973. An earthquake in Tennessee, centered about 30 miles south of Knoxville, caused minor damage in the Maryville-Alcoa area and was felt in seven Southeastern States. New Mexico experienced a sharp earthquake on December 24 that caused minor damage in the Grants area. Other parts of the world suffered fatalities and significant damage from earthquakes. In Iran, an earthquake killed one person, injured many, and destroyed a number of homes. Earthquake fatalities also occurred in the Azores and in Algeria.

Earthquakes, January-February 1974

During the first 2 months of 1974, earthquakes caused fatalities in Peru and Turkey. The largest earthquake during the period was a magnitude 7.2 shock in the New Hebrides Islands. A local tsunami was generated by a magnitude 7.0 earthquake in the Solomon Islands. The relative quiet that characterized world seismicity during the last year continued through the period. There have been no great earthquakes (magnitude 8.0 or larger) since January 10, 1971, when a magnitude 8.1 shock occurred in western New Guinea.
