An earthquake (click here) of preliminary magnitude 4.2 hit central Oklahoma on Wednesday night, the U.S. Geological Survey said, the sixth earthquake to affect the area in just over 24 hours.

Four hours later, a less intense earthquake of a preliminary magnitude 3.5 struck the area in the early hours of Thursday.

The quake late Wednesday was the largest magnitude earthquake to strike the area, near the city of Edmond, since Tuesday night. The USGS said the earthquake was "widely felt" in Edmond and northern Oklahoma City, which is located about 15 miles away. It happened a few minutes before 10 p.m. local time at a preliminary depth of 2.3 kilometers (1.43 miles).

The Edmond police department said on Twitter that no significant damage had been reported.

Residents said the "earthquake cracked floors and walls, and knocked household items off shelves and counters," reporter Joe Wertz of StateImpact Oklahoma reports for NPR.
