DANGER ZONE




                     PHILIPPINE


                     EARTHQUAKE





                  All around the Pacific Ocean, people live under the
                  constant threat of earthquakes caused by the ocean
                  floor grinding beneath nearby continents. Worst hit are
                  regions that lie near the deep ocean trenches, especially
                  in the high-risk earthquake zone, known as the Pacific
                  Ring of Fire. This includes the Philippines, which have
                  suffered more than 25 earthquakes since the year 2000—
                  there were nine earthquakes in 2012 alone. The sudden
                  fracture of the earth generates shock waves that cause
                  chaos, wrecking whole communities and claiming lives.
