The Pennsylvania Emergency Management Agency, or PEMA, says coordination after this week’s earthquake went according to plan. The scope of Tuesday’s earthquake was small enough that PEMA allowed the various state agencies – like PennDOT, and the Public Utility Commission-to work independently to send out infrastructure status updates. Ruth Miller, a PEMA spokeswoman, says the agency did not fully activate its joint information center. Therefore, PennDOT and The PUC handled their press releases containing public messages from their own offices. PEMA says damages resulting from the quake were minor. There were a few reports of broken windows in residential buildings, and the occurrences were not concentrated in any particular region. A spokesman for Exelon Nuclear, which operates three nuclear power plants in the state, says the facilities declared the lowest emergency alert level on Tuesday and returned to normal operations a few hours later.
