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.

Residents living in the Inland Empire may have been woken by a series of earthquakes that shook the area during the early morning hours on Wednesday. The first was a 3.5 magnitude quake that struck at 1:02 a.

The same region has been struck by a series of similar-sized earthquakes in recent weeks, when a 3.1-magnitude quake rattled Big Bear Lake in the San Bernardino Mountains and several different temblors struck on the same day centered near Rialto and Muscoy,
