As of April 29, 69 people local to Redlands submitted responses. So far, responders have signified feeling weak to light “shaking.”

Additionally, some residents in Riverside, approximately 14 miles from Redlands, and San Bernardino, about seven miles from Redlands, reported feeling the quake. 

Hundreds of more people filled out the corresponding form for the Granite Bay earthquake. As of April 29, 771 people near the area reported their experiences.
