There should be no cause for alarm among Saipan residents because these earthquakes were not felt here, according to EMO seismic supervisor Juan T. Camacho.
The newly installed wide-screen monitor that receives data from seismic stations on the Northern Islands showed the epicenters of the earthquakes, and provided information on the exact time and distance of each epicenter to the other CNMI islands.
The first two earthquakes shook Pagan on Nov. 30. One measured 5.0 on the Richter scale and took place 80 miles east of Pagan at 10:04 p.m. An aftershock followed at 10:33 p.m.
The third earthquake registered 5.9 on the Richter scale, originating 25 miles north-north-east of Agrigan and 265 miles north of Saipan at 10:31 p.m. on Dec. 2.
A 4.7 earthquake with its epicenter 90 miles east of Alamagan and 200 miles north-north-east of Saipan was recorded at 6:30 p.m. onDec. 4.
Camacho said it’s the first time this year that four earthquakes were felt in the Northern Islands within a week.
EMO, he said ,continues to coordinate with the U.S. Geological Survey and the National Earthquake Information Center in monitoring earthquakes.
