The area around Reno, Nev., continues to shake as another moderate earthquake has been recorded in the region.
The 4.2 magnitude earthquake was reported a 4:33 a.m. Monday and was followed by at least a dozen aftershocks, according to the University of Nevada, Reno, Seismology Laboratory.
It's the latest in a two-month swarm of earthquakes that started in February.
Scientists say the events are unusual because they are getting stronger, instead of weaker.
The strongest temblor so far was Friday night, when a 4.7 earthquake dumped cans off shelves, knocked pictures off walls and pushed rocks off hillsides along the Sierra Nevada.
No injuries were reported.
