Why are tsunami waves hitting Japan after Kamchatka earthquake smaller, but those barreling towards Hawaii, Ecuador nearly 10 feet high?
Tsunami waves have started to crash along the coast of Russia's far east and some islands and Japan following the world's sixth-most powerful earthquake on the Pacific Ocean seafloor in Kamchatka Peninsula on Wednesday. Hawaii in the US including the country's and Canada's western coast are also bracing for powerful waves as warnings and watches have been issued for many regions. The massive earthquake on July 30 measuring 8.8 according to the US Geological Survey (USGS) had its epicenter nearly 74 miles (119 kilometers) southeast of Petropavlovsk-Kamchatsky in Russia's Kamchatka Peninsula. The quake's depth was 20.7 kilometers, prompting the USGS to issue tsunami warnings. Even parts of South America including Ecuador have issued tsunami warnings for regions along the Pacific coast.

The region along with Russia's far east and Ecuador are likely to face the most ferocious tsunami waves even though the US state and the South American nation are several thousands of kilometers away from the earthquake epicenter. Also Read: Tsunami waves slam Japan's Hokkaido and Russia's Kuril Islands after massive 8.8 quake off Kamchatka; Hawaii, Alaska on high alert Japan's northern regions and Russia's Kuril Island were the first to be hit by tsunami waves after the quake. But the waves were enormous as expected. The waves which crashed into the above-mentioned regions were only about 1 to 1.5 feet high, even though the initial forecast was they would reach a height of up to 10 feet (3 meters). These regions are closest to the quake epicenter in Kamchatka Peninsula with Japan's northern islands just 1,000 miles (1,600 kilometers) away. What US Tsunami Warning Syatem says? However, US Tsunami Warning System maintains that Hawaii and Ecuador will face much bigger tsunami waves. While Hawaii is more that 3,000 miles (4,800 kilometers) away from the epicenter, Ecuador lies 8,000 miles (12,800 km) away from Kamchatka Peninsula. Live Events So why are the tsunami waves hitting Japan smaller and those expected in Hawaii and Ecuador much higher? According to seismologists, the strength and height of a tsunami depends on the nature and direction of the earthquake. When an earthquake strikes under water on a sea or ocean floor, it displaces huge quantities of water resulting in a tsunami. The height and strength is directly dependent on the direction of the water displacement. Also Read: Massive earthquake of magnitude 8.8 strikes Russia's far east, biggest since 2011; details inside The tsunami waves are pushed in the direction of the fault line rupture due to the quake. So the strongest and highest tsunami waves move out in one direction. While the seismic waves travel in all directions and the waves rise across all the basins, the maximum energy is in the direction of the rupture. The Kamchatka earthquake released the maximum energy towards Hawaii and Ecuador. So, seismologists predict the highest tsunami waves will hit these regions even though they are several thousands of miles away from the quake. The first waves will reach Hawaii around 7:17 p.m. HST (1:17 a.m. ET). These are expected to be 10 feet (3 meters) high. Other coasts in Hawaii will also be hit by waves reaching up to 3 to 9 feet (1-3 meters). Economic Times WhatsApp channel )

New Zealand braces for strong currents as tsunami waves barrel across Pacific after Russia's Kamchatka earthquake
A massive earthquake of 8.8 magnitude in Russia's Kamchatka Peninsula on Wednesday (July 30, 2025) triggered a warning in coastal regions of New Zealand. According to New Zealand media, the National Emergency Management Agency (NEMA) has issued a warning of strong and unusual currents along all coastal areas of the country. According to the agency, the first tsunami-affected waves were expected around midnight, near Lottin Point. It is a coastal region on the East Cape of New Zealand, known for fishing and diving. "The first tsunami activity may not be the most significant," NEMA said. Explore courses from Top Institutes in Please select course: Select a Course Category As part of the advice issued, those in the water and nearby areas are asked to get out and stay away. "People on boats, liveaboards, and at marinas should leave their boats/vessels and move onto shore. Do not return to boats unless instructed by officials," NEMA said, according to news website Stuff. The unpredictable surges were expected to continue for several hours, and the threat was real until the advisory was cancelled, the agency said. A tsunami has hit coastal areas of Russia's Kuril Islands and Japan's large northern island of Hokkaido following the powerful earthquake in Russia. Warnings are also in place for Alaska, Hawaii, and other coasts south toward New Zealand. Emergency mobile alert sent Live Events An emergency alert was sent to people across New Zealand. "Strong currents and surges can injure and drown people. There is a danger to swimmers, surfers, people fishing, and anyone in or near the water close to the shore. People on boats, liveaboards, and at marinas should leave their boats/vessels and move onto shore. Do not return to boats unless instructed by officials," the alert said, as quoted by the New Zealand Herald. "If you are onshore, you do not need to evacuate. But stay away from the water," the alert read. The warning was for all coastal areas of the North Island, South Island, Stewart Island, and the Chatham Islands. Kamchatka Earthquake: Alerts sounded in multiple places The earthquake that struck Russia's Kamchatka was the sixth-largest on record. It prompted tsunami warnings in Hawaii, Alaska, California, and Japan, leaving millions across the Pacific anxiously awaiting waves that forecasters said could reach up to 10 feet. The earthquake, about 78 miles east-southeast of Petropavlovsk-Kamchatsky, Russia, took place at 7:24 p.m. Eastern time Tuesday, according to the U.S. Geological Survey. Several warnings, as well as advisories and watches, were issued along the entire West Coast of the continental United States. It reverberated across vast stretches of the Pacific, triggering alerts from Alaska to parts of Asia and as far as South America. As far as Alaska is concerned, the warnings were concentrated along a chain of volcanic islands in the North Pacific Ocean. Just before 11:30 p.m. Eastern time, forecasters issued a warning for a region in California near the state line with Oregon, where they said waves could reach up to 5 feet. That stretch of coastline has had frequent experiences with tsunamis over the past century. Crescent City, about 20 miles south of the Oregon border, has been hit by 32 tsunamis since 1933. The Russian authorities raised tsunami warnings for two of the Kuril Islands, Paramushir and Shumshu, and the Kamchatka region. The first small wave was estimated to have hit the Kurils around noon local time, authorities in the Sakhalin region said on Telegram. Warning in Japan Authorities in Japan said waves along the country's Pacific coast could reach 3 meters, or 10 feet. A ferry linking the main Japanese islands of Honshu and Hokkaido was suspended, Japan's public broadcaster NHK reported. The impact of the quake swept vast stretches of the Pacific Ocean, prompting advisories as far away as Chile, where the U.S. Tsunami Warning System warned that waves could be nearly 10 feet high.
