Aftershocks still hitting downstate

WEST SALEM, Ill. -- The number of aftershocks linked to last week's earthquake continues to grow.

The U.S. Geological Survey says 22 aftershocks have been recorded since last week's 5.2-magnitude temblor with its epicenter near West Salem in Edwards County.

The aftershocks include one just before 12:40 a.m. Monday that registered a 4.0 magnitude at its epicenter northwest of Mount Carmel. That temblor, in the same area as Friday's earthquake, had been reported as 4.5 before being downgraded.

The strongest aftershock hit about 5½ hours after Friday's quake and registered a 4.6-magnitude.

None of the eleven aftershocks since then with epicenters in Illinois have been that strong.
