In Japan, a magnitude 7.6 earthquake on January 1 killed 213 and sent 26,000 to emergency shelters. Satellite photos suggest the earthquake displaced the coastline 800 feet (250 meters). The earthquake raised beaches the size of two football pitches and dried bays on Japan’s Noto Peninsula.
Widespread Coastal Alteration: Japan’s Earthquake-Induced Land Uplift Revealed in Satellite Images
Evidence of land uplift at over 10 coastal locations suggests this dramatic coastal alteration is widespread. Nahel Belgherze, a French electronics technician, posted satellite photographs on X (previously Twitter) showing the Noto Peninsula’s before and after. Ground level rise exposed previously submerged land in the images.
Amazingly, the earthquake caused land uplift, moving the coastline 250 meters offshore. The photographs show the geological influence and the land’s resilience to seismic activity.
Japan has an advanced seismic detection network due to its earthquake risk. This network uses GPS stations strategically placed nationwide to track ground displacement after seismic events. The network’s sensitivity allows precise seismic displacement estimations.

Earthquake Impact: Noto Peninsula’s Resilience and Geological Changes
Belgherze’s photographs demonstrate the Noto Peninsula’s resiliency and the exposed underwater sections. Visual evidence shows how the earthquake changed the region’s topography.
This earthquake event caused devastating human losses and reminded us of Earth’s dynamic geological processes. Satellite photography helps us comprehend Earth’s dynamic processes by capturing and sharing these changes following catastrophic disasters. After this earthquake, Japan’s shared photographs show the scope of geological shifts, stressing the necessity for continuing monitoring and preparedness in earthquake-prone areas.
