Three earthquakes occurred in the past three days near Farallon de Pajaros and Pagan, but no one was reported injured nor was there damage to property.
The Pacific Tsunami Warning Center did not issue any warnings or advisories, according to the CNMI Emergency Operations Center.
A 4.6-magnitude earthquake happened yesterday at 5:59am some 157.21 miles of Farallon de Pajaros.
On Sunday at 3:35am, a 4.0-magnitude temblor occurred 50 miles south southwest of Pagan.
Before that, on Sunday, at 6:32am, a 4.9-magnitude earthquake jolted an area 69 miles east of Pagan.
Last Wednesday, March 7, a 5.1-magnitude earthquake occurred 19 miles southwest of Pagan.
Five earthquakes recently occurred near Rota and Saipan in a week.
U.S. Geological Survey seismologist Aaron G. Wech earlier told Saipan Tribune that the recent earthquakes were the result of the Pacific plate colliding with and sinking beneath the Philippine Sea plate.
Wech said the series of earthquakes are to be expected in tectonic settings like the CNMI.
