Tsunami alerts were issued for Alaska and Hawaii on Tuesday after a major, 8.8 magnitude earthquake struck off the coast of Russia, according to officials.

A magnitude 8.8 earthquake rocked Russia’s eastern peninsula and has led to evacuations in Hawaii and elsewhere.

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

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

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

A massive 7.4 magnitude earthquake struck off the coast of Russia’s Kamchatka Peninsula, triggering tsunami warnings and widespread concern. Within just 32 minutes, two more quakes followed — a 6.7 and a 5.
