The year 1976 started out quite active, seismically. Four major earthquakes occurred in different parts of the world during the first 3 months of the year. Three earthquakes rattled the western rim of the Pacific Ocean from the Kuril Islands to the Kermadec Islands. The fourth major earthquake struck Guatemala, killing thousands of people, injuring many, and leaving thousands homeless. Earthquakes in Kentucky and Arkansas caused little damage but were felt in several States. Arizona experienced a sharp earthquake in the Chico Valley, which caused very little damage. Other States experienced earthquakes, but none caused damage.
