An earthquake on Sept. 23 cracked the concrete in San Gregorio Atlapulco, Mexico
ASK MOST AMERICANS ABOUT THE
greatest disaster threat and they’re
likely to give the same answer:
hurricanes—especially after the
recent havoc they’ve wreaked. That
awareness is valuable. But it’s just as
important to realize how vulnerable
we are to another kind of disaster:
earthquakes.
Consider the Sept. 19 quake near
Mexico City. At least 333 people
died and 38 buildings collapsed, and
those tallies could rise. It was a grim
reminder of just how devastating a
seismic event can be. And it could
have easily happened in the U.S.—
not just in California but in cities like
Memphis, New York, Anchorage, Salt
Lake, Seattle and Washington, D.C.
Large swaths of the U.S. are overdue
for a seismic event(see chart). Few
are as prepared as Mexico City.
Mexico’s recent quake occurred
32 years after the city’s 1985 shock,
which killed about 10,000 people
and destroyed 3,000 buildings. Since
then, Mexico has worked to shore
up its earthquake preparedness. In
‘WE CAN MAKE IT A LOT HARDER. AND THAT’S WHAT WE’RE GOING TO DO.’—NEXT PAGE
