If you placed a dot on a world map to represent the location of every earthquake in the last 100 years, where would you see earthquake activity most concentrated? why is this so?

If we are to place dots to teh places that have been struck by an earthquake these past 100 years, the dots would be concentrated in the east and southeast Asia region. This is because of the presence of the Pacific ring of fire. This is a major area in the Pacific Ocean where most of the earthquakes are likely to occur.
