Earthquake risk in Chile, plus an ancient Greek island and casino pollution in this week’s news
Web edition : 3:10 pm
Andes quake risk
People living on the west side of the Andes generally expect large earthquakes, like the magnitude-8.8 quake that struck last year off the coast of Chile. But those farther inland are also at risk, a new study suggests. Global-positioning data show that the ground east of the central Andes, such as in eastern Bolivia, moves far less than the west and hence might be building up stress. Earthquakes as large as magnitude 8.7 to 8.9 — not 7.5, as previously thought — could thus strike where 2 million people live. Researchers led by Benjamin Brooks of the University of Hawaii at Manoa report the finding online May 8 in Nature Geoscience. —Alexandra Witze
