BREAKING NEWS: Tsunami Warnings Issued in Western Japan After Magnitude 7.5 Earthquake Strikes
In a shocking turn of events, a powerful 7.5 magnitude earthquake has struck western Japan, prompting widespread tsunami warnings along the coastal regions. The quake, which was detected at a shallow depth of only 10 kilometers, has sent shockwaves of concern throughout the region. As reports come in, it seems that at least three strong aftershocks have also been recorded.
To gain more insight into this alarming situation, we turn to Dr. Mohamed Heidar Zadeh, a world-renowned expert in the field of geodesy and geophysics. Dr. Zadeh is a Senior Lecturer at the University of Bath and serves as the Secretary General of the Joint Tsunami Commission of the International Union of Geodesy and Geophysics.
Dr. Zadeh has shed light on the severity of the incident, drawing parallels to the devastating 1993 Hokkaido Nancy Oki earthquake and tsunami in the same region. He emphasizes that the current earthquake, similar in magnitude, poses a considerable threat due to its shallow depth. Notably, the sea of Japan, where the quake occurred, is a closed basin, presenting a different tectonic setting than the more widely known Pacific side of Japan.
The potential danger is underscored by the memory of the 2011 earthquake and tsunami on the Pacific side, which claimed the lives of over 20,000 people. The closed nature of the sea of Japan can exacerbate the impact of tsunamis, leading to prolonged oscillations and flooding. Dr. Zadeh warns that this particular landscape, with its semi-enclosed basin, can generate long waves lasting for 24 to 48 hours, amplifying the potential destruction.
Current reports indicate that the tsunami warnings issued earlier in the morning were not issued in vain. Tsunamis have, indeed, struck the coast, and an ongoing major tsunami warning remains in effect for the Notto area, where waves of up to five meters (16 feet) are expected. Dr. Zadeh corroborates these predictions, stating that offshore gauges have already recorded wave heights of around one meter, serving as a serious indicator of the impending danger.
The severity of the situation is magnified by the presence of eight to nine nuclear power plants located along this side of Japan. Understandably, the Japanese government has taken precautions to move these facilities away from the historically more dangerous Pacific side. However, Dr. Zadeh expresses concern that sea walls alone may not be sufficient to safeguard these structures against the force of tsunamis. He underscores the importance of alternate plans, such as early shut-offs and other measures, to ensure the safety of these nuclear plants.
As the situation continues to unfold, it is crucial for residents in affected areas to heed the warnings and evacuate to safer grounds. Japan is no stranger to the devastating power of tsunamis, and lessons learned from previous incidents are guiding the response to this latest threat. Our thoughts are with those affected and our gratitude goes out to the dedicated experts and authorities working to keep the population safe.
