Earthquakes are impossible to predict, but a team from Japan located a tremor deep inside Earth and are saying the shake is related to a storm. The ocean floor between Greenland and Iceland was hit especially hard, causing the tremor. The waves scientists detected were S waves (there are two types of waves when discussing earthquakes: P-waves and S-waves) and S waves are much more faint. Hopefully this discovery makes tracking what occurs inside Earth simpler.
