Satellite images reveal land uplift from Japan's 7.6-magnitude earthquake. The satellite analysis and on-site surveys indicate that the earthquake caused significant land uplift along the coast, raising it by approximately 4 meters or 13 feet. This uplift has led to the emergence of new beaches along the Noto Peninsula, where the sea floor now exceeds water levels in various locations.
According to the University of Tokyo, the earthquake has increased the coastline in some areas by up to 250 meters, or 820 feet. This extension is roughly the length of 2.2 American football fields.
Residents engaged in fishing activities in a bay on the peninsula have observed that the entire coastline experienced uplift during the earthquake. They noted that the uplift in the bay coincided with the seismic event and that the ensuing tsunami did not reach the elevated port, according to a translation from Japanese to English provided by Google.
The Geospatial Information Authority of Japan has releasedan initial satellite analysis of the Noto Peninsula. By comparing satellite images taken in June 2023 with those captured in the aftermath of the earthquake, the agency has identified several areas where new coastlines have formed. The university mentioned that its ongoing investigation along the coast is still in progress.

Effects Of The Earthquake

Marked as the most potent earthquake in the region in over four decades, as per the U.S. Geological Survey, the seismic event led to widespread destruction. Houses crumbled, fires erupted, and military personnel were mobilized to assist in rescue operations, as communicated by government spokesperson Yoshimasa Hayashi to reporters. Tragically, an elderly man lost his life when a building collapsed in Shika Town in Ishikawa.
Footage from local media in the prefecture depicted a building disintegrating into a cloud of dust in the city of Suzu, alongside a significant crack in a road in Wajima. The scenes captured parents anxiously clutching their children in response to the unsettling events.

Nuclear Plants

Japanese Prime Minister Fumio Kishida informed reporters that he had directed search and rescue teams to exert every effort to save lives, despite facing challenges in reaching earthquake-affected areas due to blocked roads.
In response to the disaster, the Imperial Household Agency announced the cancellation of Emperor Naruhito and Empress Masako's scheduled New Year appearance on Tuesday.
The earthquake occurred at a delicate moment for Japan's nuclear industry, which has encountered strong opposition since the 2011 earthquake and tsunami resulted in nuclear meltdowns in Fukushima, devastating entire towns.
Recently, Japan lifted an operational ban on the world's largest nuclear plant, Kashiwazaki-Kariwa, since the 2011 tsunami. The Nuclear Regulation Authority stated that no irregularities have been detected at nuclear plants along the Sea of Japan, including the five active reactors at Kansai Electric Power’s Ohi and Takahama plants in Fukui Prefecture.
Hokuriku's Shika plant in Ishikawa, the nuclear power station closest to the epicenter, had already halted its two reactors for routine inspections before the quake and reported no impact from the seismic event, according to the agency.
