The U.S. Geological Survey says the 5.7 quake was centered 85 miles from Michoacan's capital, Morelia. An earlier 5.0 quake struck 114 miles off the coast of Cabo San Lucas in the state of Baja California Sur. Neither state reported serious damage or injuries.
Many businesses were closed for a holiday in Mexico City, which has been rocked by a series of strong earthquakes and aftershocks in recent days, and offices and streets were largely empty.
