The epicenter of the Monday-night earthquake was some five miles southeast of Ocotillo, California. The earthquake jolted the area at 9:27 p.m. Monday, according to Richard Buckmast who is a geophysicist at the United States Geological Survey. At 10 p.m. on Monday Yuma Fire Department spokesman Mike Erfert stated that there was no damage done to the region.
Then Yuma Sun had an interview with Buckmast from the USGS regional headquarters in Golden, Co. who told that they observed almost 30 aftershocks of 2.5 or of greater intensity including four aftershocks which had the magnitude equal to or greater than 4. Buckmast was of the firm
view that all these earth quakes are the aftershocks of 7.2 Easter Day earthquake. He told that they are still experiencing the aftershocks of Eater Day earthquake because that earthquake has a ‘long tail’ of minor aftershocks which are expected to continue over an extended period of time.
The April 4 earth quake played havoc on Mexicali and dismantled 150 buildings in San Luis, Rio Colorado, Son., Mexico. The recent earth quake which jolted the area on Monday was not a deep earthquake as it had the depth of only 4.3 miles. It means that it would not have affected people more strongly. He told that if any earthquake is shallow, it would strongly impact the people and buildings on the surface of the earth.
