A 0.43-magnitude earthquake gave some Northeast Philadelphia residents a tiny jolt early Wednesday.

The temblor was confirmed by Lamont-Doherty Cooperative Seismographic Network in New York, though seismologist Mitchell Gold said he had to look very hard to find the evidence. It was recorded at 6:37 a.m.

Gold said it was about 2 kilometers (1.2 miles) west of Cornwells Heights, close to where a 1.72-magnitude quake struck May 27. The largest earthquakes in the region in recent decades occurred in 1994, when two quakes measuring 4.2 and 4.6 hit Reading on the same day, Gold said.
