WASHINGTON — Five years ago Tuesday, a magnitude 5.8 East Coast earthquake rattled D.C., sparking brief panic and evacuations of major government buildings and causing lasting damage to the Washington Monument and the National Cathedral.

The terrifying, perplexing incident happened live on the radio.

Former WTOP anchor Richard Day was in the studio when the quake struck. Shortly after 1:53 p.m., he cut into a story on the science behind how dogs smell. “We have been feeling the shakes here in Northwest Washington,” he said. The phones in the WTOP newsroom were ringing off the hook.

Later, more details began pouring in. WTOP afternoon anchor Shawn Anderson began filling in some of the blanks in this breaking news update.

WTOP reporter Michelle Basch was in her car near L’Enfant Plaza. When the car began shaking up and down, her first thought was: “Is somebody playing a trick on me?”
