Tsunami Warning Live Updates: A powerful magnitude 8.0 earthquake struck off Russia’s Kamchatka Peninsula early Wednesday, prompting Japan’s meteorological agency to issue a tsunami alert for its Pacific coastline. The alert was an upgrade from an earlier advisory, with officials warning that tsunami waves up to three meters could hit northern Japan’s coastlines in under 30 minutes. The quake, located around 250 kilometers from Hokkaido, was shallow – making tsunami generation more likely, experts say. Japan has activated an emergency taskforce, while Hawaii, Alaska, and parts of the US West Coast are also under varying levels of tsunami warnings or watches. In Petropavlovsk-Kamchatsky, the Russian city closest to the epicenter, residents rushed into the streets as buildings swayed and power outages were reported.
A red alert has been issued by the Colombian government for its Choco region after the weather department predicted strong waves of tsunami in the area.
Gustavo Petro, the country’s President has ordered swift evacuation of beaches, low-lying areas and relocating the people in these areas to a safer locality.
The Japanese weather department has revoked all warnings linked to tsunami and lowered them down to mere advisories.
Japan is now placed under only advisories and forecasts.
Meanwhile, Northern California is still facing the tsunami warning, and it covers roughly 40 miles, from just south of Klamath to the Oregon border, including Crescent City.
A meteorologist working in the National Weather Service said that while the tsunami has affected some parts of coastal California, its influence has been lesser in Southern California.
He stated that areas such as the Port San Luis region, Ventura Harbor, and even parts near Santa Monica are facing gentler effects; they still can develop into beach flooding and robust rip currents due to the rise in water.
The expert said that people still need to be alert despite the improvement in the situation, as it could change rather quickly.
Tsunami Watch: This means that the weather department has issued a “hazardous weather” alert in place, but its location and timings are unconfirmed. The residents of the area where a “tsunami watch” has been issued are expected to keep an eye out for “information” and take “action if necessary.”
Tsunami advisory: Just a level above “watch,” an “advisory” serves more like a warning and is issued when extreme weather is already in effect. This also means that the residents near water should take more precautions and people should avoid going near beaches, as there are chances of high waves.
Tsunami warning: This is the most dangerous alert, as it means that coastal flooding and strong currents are highly likely, and the situation could turn extremely dangerous for life and property. Residents are expected to vacate their place and temporarily move to higher places.
The officials have now reduced the threat of “warning” to “advisory” in Hawaii, media reports said.
Pacific Tsunami Warning Center Director Chip McCreery has said that the “worst part” of the tsunami is over, reports said.
Now, the only area in the U.S. where the “warning” threat is still in place is Northern California.
Video footage showed that the Haleiwa Boat Harbor on Oahu’s North Shore was flooded with tsunami waters.
Two speedboats were docked in the area which looked completely vacant despite the presence of a few cars.
Reports said that flooding in the area had reached ankle level just after 9:00 p.m, but swiftly retreated by around 9:15 p.m.
Earlier, the Haleiwa region was hit by tsunami waves that surged up to 4 feet and the officials asked people to take urgent actions to safeguard themselves.
Tsunami waves entered the U.S. West Coast Wednesday morning and impacted shorelines alongside California, Oregon, and Washington. Reports say the largest waves were recorded in :
California is still under a tsunami warning and advisories are in effect for the remaining part of the California coast which also includes the San Francisco Bay Area and the coasts of Oregon and Washington.
The initial waves might be followed by additional surges and dangerous currents for many hours, officials have warned.
California is on high alert after tsunami waves struck Hawaii, following a powerful 8.8-magnitude earthquake that hit Russia’s Far East early Wednesday. The quake triggered tsunami warnings across several countries, including parts of the United States.
Authorities in California have advised residents along the coast to evacuate low-lying areas and seek higher ground. According to the National Weather Service’s Tsunami Warning Center, the first waves could reach the Bay Area coastline as early as 12:30 a.m. on Wednesday, July 30
The Japan Meteorological Agency reported that a tsunami wave reaching 1.3 meters (4.3 feet) was detected at Kuji Port in northeastern Japan’s Iwate prefecture. Authorities noted that the tsunami waves are continuing to increase in size.
The National Oceanic and Atmospheric Administration has reported a tsunami wave measuring more than five feet hitting Kahului, located on the north-central shoreline of Maui island in Hawaii.
Electricity supply has been disrupted in Russia’s Sakhalin region after an earthquake caused significant damage to the local power grid, according to the RIA news agency, which cited the regional governor.
As previously reported, a state of emergency has been declared in the northern Kuril Islands. Footage from the area shows tsunami waves flooding a coastal port town.

Tsunami waves have begun hitting Hawaii, according to an alert issued by the Pacific Tsunami Warning Center. The agency emphasized the need for immediate precautions to safeguard lives and property, warning that the threat could remain for several hours.
Authorities in Severo-Kurilsk, located at the southern edge of Russia’s far eastern Kamchatka Peninsula, have declared a state of emergency following a powerful earthquake and resulting tsunami, Russian state outlet TASS reported.
The 8.8 magnitude quake struck off the peninsula’s coast early Wednesday, triggering multiple tsunami waves that struck Severo-Kurilsk. The waves reportedly ripped boats from docks and swept away large storage containers, as seen in footage shared from the area.
Amid renewed tsunami alerts in Japan, online users are revisiting a chilling prophecy by Ryo Tatsuki, a Japanese manga artist who has previously claimed to possess clairvoyant abilities. Tatsuki had foretold that Japan would face a major disaster in July 2025, a prediction that led many to cancel travel plans well before the month began.
Her forecast appeared in a 2021 reprint of her 1999 manga The Future I Saw, which warned of a “catastrophic disaster” expected to hit Japan on July 5, 2025. According to reports, the manga described a massive undersea rupture forming between Japan and the Philippines, resulting in a tsunami “three times more powerful than the 2011 Tōhoku disaster.”
On March 11, 2011, a massive undersea earthquake with a magnitude of 9.1 struck off the northeastern coast of Honshu, Japan’s main island. The powerful tremor triggered a devastating tsunami within just half an hour. The quake occurred along the Japan Trench, a subduction zone where the Pacific Plate dives beneath the Okhotsk microplate.
This remains the strongest earthquake ever recorded in Japan and ranks as the world’s fourth most powerful since 1900.
The quake was felt across all of Japan and sent shockwaves as far as China, Taiwan, and parts of Russia. In the aftermath, the region experienced hundreds of aftershocks, with several exceeding magnitude 7.0.
Tsunami activity along Japan’s eastern coastline could persist for at least 24 hours, according to the country’s meteorological agency. Waves reaching up to 60 centimeters (around 2 feet) have continued to strike the region since the recent undersea earthquake.
“Based on previous earthquakes of similar magnitude, we anticipate that elevated tsunami conditions may continue for at least a day,” a spokesperson from the agency stated on Wednesday.
In a fresh advisory, officials also cautioned that tsunami waves often arrive in multiple surges. They urged residents in affected zones to remain in safe locations until all warnings and advisories are officially lifted.
Over 1.9 million residents across Japan have been advised to evacuate to safer locations as tsunami waves impact several coastal areas, causing widespread transport disruptions across the country. However, the wave heights have remained significantly lower than early predictions.
The Fire and Disaster Management Agency has released localized evacuation directives affecting approximately 1,905,596 individuals across 21 prefectures. The largest evacuation figures come from Hokkaido, Kanagawa, and Wakayama.
The initial tsunami waves struck Japan’s northernmost island, Hokkaido, where footage shared by Reuters and Nippon News Network showed people seeking refuge on rooftops. Tsunami alarms echoed throughout parts of the island on Wednesday morning.
According to the Japan Meteorological Agency, tsunami waves measuring between 30 and 50 centimeters have been observed along the eastern coastline, advancing toward the Tokyo Metropolitan Area
The Kamchatka Peninsula experienced its most powerful earthquake since 1952 on Wednesday, prompting officials to caution residents about the likelihood of strong aftershocks.
According to the Kamchatka branch of the Russian Academy of Sciences’ Geophysical Service, significant aftershocks with magnitudes reaching up to 7.5 are anticipated to persist for at least a month.
This recent seismic event is part of a continuing pattern of earthquakes affecting the region over the past ten days. Notably, on July 20, the peninsula recorded five earthquakes, including a major tremor of magnitude 7.4 near Petropavlovsk-Kamchatsky, the regional capital.
Local broadcaster NHK reports that a tsunami has struck the northern region of Japan’s Hokkaido prefecture.
The earthquake near the Kamchatka Peninsula on Wednesday is the strongest recorded since 1952, according to the Russian Academy of Sciences’ Geophysical Service. The seismic event triggered hazardous tsunami waves along the nearby coast.
In a Telegram post, the Kamchatka division of the agency cautioned, “Considering the magnitude of this earthquake, strong aftershocks are likely, with some potentially reaching up to magnitude 7.5.”
The notice further emphasized that “significant aftershocks of up to magnitude 7.5 could persist for at least a month.”
During a press briefing in Honolulu, an emergency official addressed the public, saying, “As you watch this, please be aware that a full tsunami alert is currently in effect.”
He added, “We expect any potential impact on Hawaii to occur in a few hours. Stay alert and listen carefully for updates.”
