Several small earthquakes hit the Inland Empire early Wednesday morning, but there were no reports of damage. Ontario saw two quakes — measuring 3.5 and 3.2 magnitude — just after 1 a.m. That was followed by a 3.5 magnitude quake in Ontario and a 3.7 temblor in Lytle Creek.

A total of four earthquakes rocked the Inland Empire overnight, meaning the region experienced five quakes across a 13-hour span on Tuesday and Wednesday. The series began with a 3.5 magnitude quake at 4:55 p.m. near Rialto. The U.S. Geological Survey said it was felt throughout the I.E., including in Ontario and Fontana.
