Data from the 7.1-magnitude earthquake that rocked Mexico Tuesday was recorded as far away as Fordham University's seismic observatory.

The observatory is housed in an underground observatory, one of the oldest seismic labs in the country. Monitoring devices have been recording earthquake activity around the world for nearly a century.

"About seven minutes after the earthquake, we started detecting the beginning of that rumbling. It escalated over the next 10 minutes or so," says Dr. Stephen Holler.

Tuesday's seismic action was the second earthquake in two weeks to strike Mexico.

"By the time it hits us, the energy was still there," he says. "We were still able to pick it up with our sensitive instrument. In terms of actually physically feeling it, no."
