The Pacific Tsunami Warning Center of Honolulu says there is no tsunami threat following an 8.0-magnitude earthquake in the Drake Passage. The earthquake struck at about 4 :35 p.m. at a depth of 10 kilometers in the Drake Passage—a body of water located between the southern tip of South America and the South Shetland Islands of Antarctica.

An advanced, real-time tsunami forecasting system could dramatically improve early warning capabilities for coastal communities near earthquake zones.

Information from a satellite is providing scientists with a unique look at the tsunami, a breakthrough that could have implications for early warning systems.

Ancient 2,000-year-old artifacts were recovered from the Mediterranean Sea near Alexandria, Egypt, possibly from the sunken city of Canopus.

A snug cockpit fit makes a kayak feel like the lower half of a paddler’s body. Each twitch, pitch, or hitch of the hull informs the paddler where and how to throw a stroke, many of which are brace strokes that can keep the kayak from overturning — just think of that paddle blade as a temporary pontoon.
