The first day of 2024 brought catastrophe to parts of Japan. At 4:10 p.m. Japan Standard Time (07:10 Universal Time), the land on the Noto Peninsula in northwestern Honshu began to lurch, shaking violently for about 50 seconds. The 7.5 magnitude mainshock was followed by dozens of strong aftershocks in the following minutes, hours, and days.
The earthquake on January 1, 2024, was the strongest to hit Ishikawa Prefecture since 1885 and mainland Japan since the 2011 Tohoku earthquake. Shaking was felt across much of Honshu including Tokyo, located about 300 kilometers southeast of the earthquake’s epicenter. Shaking was most intense in the towns of Suzu, Noto, Wajima, and Anamizu, close to the epicenter on the northern Noto Peninsula. Damage to infrastructure ignited fires that burned through communities. Heavy snow that fell after the quake complicated emergency response efforts, making it difficult for aid to reach some communities.
As first responders reacted to the disaster from the ground, several teams of scientists tracked the situation using satellites. The map above shows the amount of ground displacement—the shifting of the land—caused by the earthquake. Red areas were pushed upward and toward the northwest. The scattered dark blue and red areas around the airport and other cleared areas and settlements throughout the peninsula are likely false signals caused by how the shapes of buildings or other features reflect radar signals.
