Hawaii experienced a dramatic brush with nature’s power on July 29, 2025, as tsunami waves—some reaching 1.7 meters (5.7 feet)—rolled into its shores following a massive magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula. The quake, tied for the sixth-strongest ever recorded, sent warnings rippling across the Pacific, prompting emergency evacuations and widespread alert systems.
As tsunami sirens pierced the rain-soaked air on July 29, streets filled with cars and people scrambling to reach higher ground. Many residents were reminded of the devastating tsunamis in the Indian Ocean in 2004 and Japan in 2011—events that left lasting scars around the world.
“We weren’t panicked, but we knew we had to move,” said Doan Trang, a visiting surfer and mother from Dana Point, California. She and her son walked uphill for nearly two hours after hearing the sirens. “Once we crossed the bridge and saw the tsunami zone sign behind us, I felt peace.”
The first tsunami waves reached Hawaii at 19:17 local time, nearly six hours after the quake occurred off Kamchatka’s southeastern coast. Notable wave heights included 1.7 meters at Kahului on Maui, 1.5 meters at Hilo on Hawaii Island, and 1.2 meters at Haleiwa on Oahu. Many coastal areas observed sea level withdrawal just before wave arrival—a typical sign of a tsunami.
Statewide sirens and alerts led to mass evacuations. Emergency shelters opened on all islands, and ports and harbors were closed. Flights were temporarily suspended at Hilo and Kahului airports.
On Oahu, traffic clogged inland roads as residents and tourists heeded the warnings. A viral TikTok clip captured the chaos: “It’s crazy … everyone is evacuating all at the same time.”
The Norwegian Cruise Line’s Pride of America left port early to avoid the waves, stranding some passengers. Jeffery Booker from Orlando was one of them. “We knew we weren’t gonna make it,” he said. The ship later returned after the all-clear, greeted by cheers and hugs.
Jenny Massey, watching from her 28th-floor hotel balcony in Waikiki, described a night of unease: “We were nervous, just looking down at the empty beach, watching the sirens go off.”
Her son, however, was unphased. “We get to swim at the beach now. The waves are really big. It’s funner,” said Brandon.
The U.S. Coast Guard played a critical role in Hawaii’s preparedness. Capt. Nicholas Worst, head of Sector Honolulu, said, “We moved cutters, boats, and aircraft out of the harbor right away.”
He emphasized that with 98 percent of Hawaii’s goods arriving by sea, port protection was critical. “We had to be ready—for search and rescue, pollution control, anything.”
Other regions in the Pacific also recorded tsunami effects: wave heights reached 1.2 meters in Crescent City, California; 0.9 meters at Arena Cove; 0.4 meters in Port Orford, Oregon; and 0.8 meters in Adak, Alaska. Japan’s northern coast saw waves up to 0.35 meters, prompting temporary port closures in Hokkaido.
In Russia’s Severo-Kurilsk, waves between 3 and 5 meters flooded ports, displaced vessels, and damaged infrastructure, including a kindergarten. Kamchatka hospitals remained operational, and though several people sought medical care, no fatalities were reported.
By the morning of July 30, the Pacific Tsunami Warning Center lifted the advisory for Hawaii. Officials continued to warn of strong currents, but sea levels gradually returned to normal.
On the evening of July 30, Waikiki returned to its usual vibrance, bathed in golden hues as tourists waded in the surf, children laughed, and parents sipped drinks under a glowing Hawaiian sunset. But the mood had been starkly different just the night before.
Zi Glucksman, a student visiting from New York, summed up the mood shift: “We stayed calm. Now the beach is full again. It’s kind of amazing.”
Trang echoed that sentiment after returning to the water: “It could have been a lot worse. It could have been a lot of damage. But it didn’t.”
