The Pacific Ring of Fire not only generates the most earthquakes worldwide but the most TC's in the EPAC and WPAC and many other natural disasters. Not to mention the other Pacific basins in the CPAC and South Pacific. It's just a different world.

"(CNN)At least 61 people have died after the most powerful earthquake to hit Mexico in a century struck off the southern coast.

The magnitude 8.1 quake, which was felt as far as Mexico City and Guatemala City, was registered off Mexico's southern coast just as heavy rains from Hurricane Katia lashed the east. The epicenter was in the Pacific Ocean, some 600 miles (1,000 kilometers) southeast of the capital and 74 miles (120 kilometers) off the coast.
President Enrique Peña Nieto said the temblor -- felt by about 50 million people across the country -- was the strongest earthquake Mexico has experienced in 100 years. In September 1985, a magnitude 8.0 earthquake killed an estimated 9,500 people in and around Mexico City.
This one hit late Thursday, when many people were asleep. The states of Chiapas and Oaxaca, home to about 9 million people, are located closest to the earthquake's epicenter. They are two of the most impoverished areas in Mexico, and were likely hit the hardest."
