Synopsis

A powerful 8.8 magnitude earthquake off Russia's Kamchatka Peninsula has triggered a tsunami watch for Hawaii. Issued by the Pacific Tsunami Warning Center, the watch anticipates potential wave arrival around 7:17 p.m. HST. While no damage or deaths are reported in Russia, emergency protocols are active, and officials are closely monitoring seismic data to assess the tsunami threat.

A powerful earthquake struck off the coast of Russia's Kamchatka Peninsula, causing immediate concern throughout the Pacific. The earthquake had a magnitude of 8.8, according to the United States Geological Survey. It has prompted a tsunami warning for Hawaii, as scientists monitor for dangerous wave activity.

Massive 8.8 Earthquake Strikes Off Russia’s Kamchatka


The U.S. Geological Survey said that an 8.8 magnitude earthquake hit the eastern coast of Russia's Kamchatka Peninsula on Wednesday, July 30. The tremor, which happened at 1:25 p.m. HST, was thought to be shallow, which makes it more likely to cause a tsunami, as per a report by Hawaii News Now.

Even when they happen far away from land, shallow earthquakes can move a lot of water, making waves that can travel a long way. There are no reports of damage or deaths in Russia right now, but emergency plans have been put into action in nearby areas, and monitoring stations across the Pacific are on high alert, as per Reuters.



What does it mean that Hawaii is under a tsunami watch?


The Pacific Tsunami Warning Center sent out a tsunami watch for Hawaii just eight minutes after the quake hit, at 1:33 p.m. HST. Even though there was no proof of a tsunami at the time, the watch was put in place as a safety measure, as per a report by Hawaii News Now.

Scientists say that "based on all available data," the strong tremor may have caused a tsunami, which could have made waves that were strong enough to destroy things. These waves could go thousands of miles and affect coastal areas far away from the earthquake's center.

If these waves do reach Hawaii, they are expected to arrive around 7:17 p.m. HST at the earliest. Right now, officials are looking at seismic and oceanic data to figure out how big the threat is.

A tsunami watch is issued when an earthquake occurs that could generate a tsunami. Prepare to take action if the watch is upgraded to an advisory or warning.


What should people do if there's a tsunami?


Officials are telling people in Hawaii to stay alert and follow orders carefully. Residents should be ready to do something if a tsunami watch is issued, especially if the alert level goes up to an advisory or full warning.

The Hawaii Emergency Management Agency set up a conference call with all the counties in the state to plan how to respond. There are no watches or warnings in effect outside of Hawaii right now, but emergency teams are still on the lookout and ready.

People who live in areas that could be hit by a tsunami should check to see if they are in an evacuation zone and make emergency kits with the things they need.
