A tsunami unexpectedly swept into the Indonesian city of Palau on the island of Sulawesi at 5PM Indonesian time on Friday. The wave was over 6 meters high and flooded a significant part of the city. The death toll is not known at this time, nor is it clear how much damage has been done. As sea levels rise, they put pressure on continental shelves, which is why the Pacific Ring of Fire has been becoming steadily more active in recent years.
A powerful earthquake struck off the coast of Chile at 3:54 PM Pacific Daylight Time. The quake was at a depth of 15.5 miles and was 145 Miles NNW of Santiago. The quake struck in the Nazca Plate Region, which is one of the most active earthquake zones on the Pacific Rim and in the world. The quake took place on the South American arc, which marks the boundary between the Nazca Plate and the South American Plate and stretches approximately 6,000 miles along the South American Coast. The relatively shallow depth of the quake and the slow upward gradient of the ocean floor toward land in the region has caused the tsunami warning, but no serious wave action ensued.
Los Angeleans were given an unexpected alarm call from Mother Nature on Monday morning as an earthquake shook the city at around 6.25am.

Shortly after the Tohoku Megathrust Earthquake struck off the coast of Japan on March 11, 2011, something strange happened in Norway. People watched in astonishment and fear as tight wave action in the normally quiet fjords made them appear to boil. The water became roiled with 5 foot waves in the Auruland-Flam Fjord, and the condition waxed and waned for hours. The cause was a mystery until recently, but now a new study has shown that the wave action in Norway was linked to the Japanese earthquake.
