Earthquake Map


This is a map of the most recent earthquakes (in the last seven days) that are over 2.5 on the richter scale. This map shows 183 earthquakes, most of them located around the pacific rim. Also, most of them are at least a 5.0 or higher on the richter scale. Some of the main locations and magnitudes are a 5.4 on December 6th on the Kashmir-Xinjiang border region (not along the pacific rim); a 5.4 on December 2nd in Samar, in the Philippines; a 5.2 on December 1st in the New Britain Region, in Papua New Guinea; and a 5.0 on December 3rd in Tonga. Most of the world's earthquakes (90% of them, and 81% of the largest ones) are located along the Pacific Ring of Fire. The other ten percent are located other places around the world. The United Kingdom's earthquake recurrences, for example, are about a 3.7-4.6 every year; a 4.7-5.5 every 10 years; and a 5.6 or larger every 100 years. The magnitude of earthquakes along the Ring of Fire are much higher and occur much more frequently than in The United Kingdom.
