Reflections on when the world changed
For some, it was the realization that students would have to stay home. Or that trying to find hand sanitizer and toilet paper had become a scavenger hunt. Or that a substance abuse lifeline was closing its doors, even if temporarily.
Whatever the sign or the moment, the gravity of the deadly viral outbreak revealed itself in different ways, but the message was the same: The world was about to change.
Since the first case of COVID-19 was detected in Maine on March 12, 2020, there have been more than 46,000 cases and 723 lives lost. The death toll in the United States has topped 530,000.

Massive earthquakes are, fortunately, rare events. But that scarcity of information blinds us in some ways to their risks, especially when it comes to determining the risk for a specific location or structure. We haven t observed most of the possible events that could cause large damage, explained Kevin Milner, a computer scientist and seismology researcher at the Southern California Earthquake Center (SCEC) at the University of Southern California. Using Southern California as an example, we haven t had a truly big earthquake since 1857 that was the last time the southern San Andreas broke into a massive magnitude 7.9 earthquake. A San Andreas earthquake could impact a much larger area than the 1994 Northridge earthquake, and other large earthquakes can o
Supercomputers Simulate 800,000 Years of California Earthquakes to Pinpoint Risks
Massive earthquakes are rare events and the scarcity of information about them can blind us to their risks, especially when it comes to determining the danger to a specific location or structure.
Scientists are now working to improve the calculations of danger by combining maps and histories of known faults with the use of supercomputers to simulate potential shaking deep into the future in California. The method is described in an article just published in the
Bulletin of the Seismological Society of America.
“People always want to know: When is the next ‘Big One’ coming,” said coauthor Bruce Shaw, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory. “Chaos always gets in the way of answering that question. But what we can get at is
