Mapping Seismic Activity: Vulnerable vs. Non-Vulnerable Regions
The study of plate tectonics offers an interesting view on our planet’s past, present, and future seismic activity. The larger and expanded map indicates the probable intensity of earthquakes that could happen in the next 50 years, starting from 2004. The green lines represent the earth’s plate boundaries and the shaded colors ranging from grey to orange represent the probable intensity of an earthquake in that specific region. Each red dot on the map represents a recorded seismic event since 1900 that had a Seismic Moment Magnitude above 8.5. Dr. Jean-Paul Rodrigue, the author of this map, explains that it is a matter of when, rather than if, that these endangered areas face some sort of seismic activity in the near future.
