On 10 July 1958, a magnitude 7.9 earthquake triggered the largest wave in recorded history. Ninety million tons of rock crashed into Lituya Bay, Alaska, sending water surging 1,720 feet up the mountainside, stripping trees and soil in a single catastrophic event. Three fishing boats were caught in the bay that night. Two crews survived against impossible odds. One did not. The megatsunami redefined what scientists believed water could do and remains the defining case study in coastal hazard modelling. Also on this day: French intelligence agents sank the Greenpeace vessel Rainbow Warrior in Auckland Harbour in 1985, killing one photographer and sparking an international scandal. And in 2018, the final four members of a Thai youth football team emerged from the Tham Luang cave system after 18 days underground, completing one of the most remarkable rescue operations of the century. Clara Vale explores a day when history arrived as a wall of water, a covert bombing, and a moment of extraordinary human coordination.

• Introduction Clara sets the scene in Lituya Bay, Alaska, where a calm summer evening in 1958 turned into the most extreme recorded wave event in human history.
• The 1958 Lituya Bay Megatsunami A magnitude 7.9 earthquake triggered a rockslide that sent 90 million tons of material into Lituya Bay, creating a wave that surged 1,720 feet up the opposite mountainside. Three fishing boats were in the bay that night. Two crews survived. The Sunmore and its crew, Orville and Mickey Wagner, were lost. The event redefined megatsunami science and changed how geologists assess coastal hazards.
• The Sinking of the Rainbow Warrior On 10 July 1985, French intelligence agents bombed the Greenpeace vessel Rainbow Warrior in Auckland Harbour, killing photographer Fernando Pereira. Two agents were arrested and convicted. France initially denied involvement, then admitted it. The incident was condemned internationally as state-sponsored terrorism.
• The Tham Luang Cave Rescue On 10 July 2018, the final four boys and their coach emerged from the Tham Luang cave system in northern Thailand after 18 days trapped underground. Twelve boys and their assistant coach had been caught by flooding on 23 June. An international rescue effort involving specialist cave divers, sedation, and round-the-clock engineering brought all 13 out alive. Thai Navy SEAL Saman Kunan died during the operation.
• Closing Thoughts Clara reflects on a day that brought a wave that rewrote science, a covert operation that failed to stay secret, and a rescue that defied the odds. History arrives in many forms, reminding us the world is larger, stranger, and more fragile than we anticipate.
