MINERAL, Va. — When the "Big One" rocked the East Coast one year ago, the earthquake centered on this rural Virginia town cracked ceiling tiles and damaged two local school buildings so badly that they had to be shuttered for good. Now as the academic year gets under way, students are reciting a new safety mantra: Drop, cover, and hold on.
In this Aug. 24, 2011, photo, damage to the Washington National Cathedral is seen the day after a earthquake shook Washington and much of the East Coast.
Earthquake drills are now as ubiquitous as fire drills at Louisa County schools in central Virginia, where 4,600 students were attending classes when the 5.8-magnitude quake struck nearby on Aug. 23, 2011. Miraculously, no one was seriously hurt.
"It's the new normal," Superintendent Deborah D. Pettit said of the earthquake drills. "It's become a normal part of the school routine and safety."
One such drill is planned for Thursday at 1:51 p.m. EDT — the precise moment a year ago when the quake struck.
The unexpected jolt cracked the Washington Monument in spots and toppled delicate masonry high atop the National Cathedral. The shaking was felt far along the densely populated Eastern seaboard from Georgia to New England.
While West Coast earthquake veterans scoffed at what they viewed as only a moderate temblor, last year's quake has changed the way officials along the East Coast view emergency preparedness.
Emergency response plans that once focused on hurricanes, tornadoes, flooding and snow are being revised to include quakes. Some states have enacted laws specifically related to the quake, and there is anecdotal evidence of a spike in insurance coverage for earthquake damage.
The quake was centered 3 to 4 miles beneath Mineral, a town of fewer than 500 people about 50 miles northwest of Richmond. Yet it was believed to have been felt by more people than any other in U.S. history.
The damage, estimated at more than $200 million, extended far beyond rural Louisa County. In the nation's capital, the Washington Monument sustained several large cracks and remains closed indefinitely.
The National Park Service plans next month to finalize the contract to repair the Washington Monument. Repairs are expected to cost $15 million and require a massive scaffolding, and the landmark obelisk is likely to remain closed until 2014.
The National Cathedral reopened last November, but repairs are expected to take years and cost $20 million. The cathedral announced Thursday that it has received a $5 million grant from the Indianapolis-based Lilly Endowment Inc. With that funding in place, stonemasons were scheduled to begin active restoration Thursday afternoon. Previously, they had been stabilizing the damaged components and cataloging the damage.
In Virginia, the North Anna Power Station became the first operating U.S. nuclear power plant shut down because of an earthquake.
Was it a once-in-a-century anomaly, or are there more quakes to come?
Scientists are trying to answer that question as they pore over the data and survey the epicenter from the air.
According to the U.S. Geological Survey, much of central Virginia has been labeled for decades as an area of elevated seismic hazard. But last year's quake was the largest known to occur in that seismic zone.
"Scientists would like to know if this earthquake was Virginia's 'Big One,'" said J. Wright Horton of the USGS.
Meanwhile, the quake prompted several jurisdictions to revise their emergency response plans.
"We learned a lot, that's for sure," said Laura Southard, a spokeswoman for the Virginia Department of Emergency Management. One lesson, she said: the need to conduct post-quake assessments to size up damage.
Ultimately, 6,400 homeowners and renters in nine Virginia localities received $16.5 million from the Federal Emergency Management Agency.
Virginia, Maryland and the District of Columbia are revising their emergency planning documents to include earthquakes. The response of many East Coast residents — many of whom fled high-rise buildings — went counter to the behavior recommended by experts during a quake.
