Four geographical zones are defined along the trench that is formed due to the subduction of the Nazca Plate underneath the South American plate; they are denoted A, B, C and D from North to South; zones A, B, and D had a major earthquake after 2010 (Magnitude over 8.0), while zone C has not, thus offering a contrast for comparison. For each zone a sequence of intervals between consecutive seisms with magnitudes ≥ 3.0 is set up and then characterized by Shannon entropy and mutability.

Drylands cover 41% of Earth’s surface and are the largest source of interannual variability in the global carbon sink.

A growing body of research shows that healthy watersheds are a vital component of a well-functioning water supply infrastructure system. WRI’s Green-Gray Assessment (GGA) method allows stakeholders to value the costs and benefits of integrating green or natural infrastructure into water supply systems to improve performance.
