The geophysical events
known as La Nina and El Nino are described as prolonged (five
consecutive three month running means) below average surface water
temperatures and prolonged above average surface water
temperatures in the Central Pacific Ocean, respectively. What was
found was that after a long (severe) hot and dry El Nino and then a
severe (but cold and wet) La Nina Ecuador experienced significantly
more earthquakes and that the earthquakes were more powerful (higher
Richters; larger damage areas) and that there was more erosion. We were initially
somewhat surprised by the influence the June 15 1991 eruption of Mount
Pinatubo in the Philippines exerted on the Central Pacific water
surface temperatures. In particular, we had assumed that the typhoon
near the Phillipines and the general trend of the ash and various
gases being propelled westward would substantially weaken any
influence on climate.
