Earthquake risk in Chile, plus an ancient Greek island and casino pollution in this week’s news

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.
