Magellan called the ocean Pacífico (or "Pacific" meaning, "peaceful") because, after sailing through the stormy seas off Cape Horn , the expedition found calm waters. The ocean was often called the Sea of Magellan in his honor until

3367-540: The Philippines already in 7000 BCE. Additional earlier migrations into Insular Southeast Asia, associated with Austroasiatic-speakers from Mainland Southeast Asia, are estimated to have taken place already in 15000 BCE. At around 1300 to 1200 BCE, a branch of the Austronesian migrations known as the Lapita culture reached the Bismarck Archipelago , the Solomon Islands , Vanuatu , Fiji , and New Caledonia . From there, they settled Tonga and Samoa by 900 to 800 BCE. Some also back-migrated northwards in 200 BCE to settle

Though the building was in the direct path of the surging waters, prompt action by the school's faculty ensured that there were no casualties, with all 96 students and staff inside the school at the time of the disaster successfully escaping to higher ground. A 6.9 magnitude earthquake struck off

7462-457: The town. It was revealed months later that the national and prefectural governments had known about the direction of the plume due to forecasts by the SPEEDI computer system, but had decided not to tell evacuees in order to prevent a panic. Tamotsu Baba, Namie's mayor at the time, said the decision to withhold information from his town was akin to "murder." On 15 April 2012, the town of Namie asked

In the Southern hemisphere, because of the stormy and cloudy conditions associated with extratropical cyclones riding the jet stream, it is usual to refer to the Westerlies as the Roaring Forties, Furious Fifties and Shrieking Sixties according to the varying degrees of latitude. The ocean was first mapped by Abraham Ortelius ; he called it Maris Pacifici following Ferdinand Magellan 's description of it as "a pacific sea" during his circumnavigation from 1519 to 1522.
