An 8.8-magnitude earthquake in Russia triggered tsunami warnings across the Pacific. Here's the latest travel guidance.

After a massive earthquake struck Russia, tsunami alerts were issued for many areas, including Japan, Hawaii and California, the latter of which is nearly 5,000 miles away.

Tsunami waves have reached California and Hawaii several hours after a powerful 8.8 magnitude earthquake in Russia's Far East. The U.S. National Tsunami Warning Center said Wednesday morning that tsunami waves measuring 1.6 feet above tide level have been observed in Arena Cove in the U.S. state of California.
