One of the largest earthquakes ever recorded happened off the Russian coast, triggering tsunami warnings from the U.S. west coast to South America. In Hawaii, people clamored to the top of high-rises and a traffic rush headed away from the coast.

The sixth-strongest earthquake ever recorded has triggered waves several feet high hurtling towards coastal areas worldwide.Countries in and around the Pacific Ocean have been placed on varying degrees of alerts for anticipated tsunamis.

When a magnitude 8.8 earthquake rocked Russia's Kamchatka Peninsula on Tuesday, officials warned that damaging tsunami waves could follow. Instead, the waves that reached Hawaii and the U.S. West Coast proved smaller than initially feared.
