Transportable Array station P19K is one of the closest stations to the Iniskin earthquake origin. Solar panels power the station, and the seismometer is buried in a specially drilled borehole to insulate it from surface noise.

This illustration shows the percentage of marine animals that went extinct at the end of the Permian era by latitude, from the model (black line) and from the fossil record (blue dots). A greater percentage of marine animals survived in the tropics than at the poles. The color of the water shows the temperature change, with red being most severe warming and yellow less warming. At the top is the supercontinent Pangaea, with massive volcanic eruptions emitting carbon dioxide. The images below the line represent some of the 96 percent of marine species that died during the event.
