What is the 2011 Tōhoku earthquake and tsunami?

The 2011 Tōhoku earthquake and tsunami, also known as the Great East Japan Earthquake, was a powerful natural disaster that occurred on March 11, 2011, off the northeastern coast of Japan. It was a magnitude 9.0 earthquake, making it one of the strongest ever recorded. The earthquake was caused by the movement of the Pacific tectonic plate beneath the Okhotsk plate, resulting in a massive release of energy.

The earthquake triggered a devastating tsunami, with waves reaching heights of up to 40 meters (131 feet). The tsunami waves traveled across the Pacific Ocean, causing widespread destruction and loss of life in coastal areas of Japan. The impact of the tsunami was particularly severe due to the proximity of densely populated areas and the vulnerability of coastal infrastructure.

The disaster resulted in the loss of approximately 15,900 lives, with thousands more injured or missing. It also caused extensive damage to buildings, roads, and infrastructure, including the Fukushima Daiichi Nuclear Power Plant, which experienced a nuclear meltdown and released radioactive materials.

The 2011 Tōhoku earthquake and tsunami had significant social, economic, and environmental consequences. It highlighted the importance of disaster preparedness and response, leading to improvements in Japan's emergency management systems. The event also raised global awareness about the risks associated with earthquakes and tsunamis, prompting increased research and efforts to enhance early warning systems and disaster resilience worldwide.
