A massive 7.7 magnitude earthquake struck the ocean floor just off the northeastern coast of Japan late Monday afternoon. The violent shaking began at exactly 4:53 p.m. local time and sent panic through local communities. Authorities immediately urged all residents to evacuate the beaches and seek higher ground. Officials warned that deadly tsunami waves up to 3 meters (roughly 10 feet) could crash into low-lying coastal neighborhoods. A wave of that massive size holds enough power to flood normal buildings, destroy local roads, and wash away anyone caught in the strong ocean currents. The national weather agency broadcast emergency alerts to millions of smartphones across the region.
Thankfully, the worst fears did not become reality for the coastal towns. Exactly 2 hours after the initial shaking stopped, ocean monitoring stations measured the largest incoming waves at just 80 centimeters high. Because the ocean water stayed relatively low, the national weather agency officially downgraded the severe tsunami warning to a much lower advisory level. Minoru Kihara, the top government spokesperson, spoke to reporters as the sun went down over Tokyo. He confirmed that rescue teams found exactly 0 dead bodies and reported no major building collapses during the initial emergency search efforts. Emergency crews continue to patrol the streets just to stay safe.
The scary event still caused massive disruptions for normal people. Local leaders in several port towns, including Otsuchi and Kamaishi, issued emergency evacuation orders for thousands of scared residents. Both of these specific towns still carry deep emotional scars because a massive earthquake and killer tsunami practically destroyed them back in 2011. Transport officials also stopped all high-speed bullet trains from running on the tracks. Police officers blocked cars from entering several major motorways to prevent bad traffic accidents during the shaking. Many families grabbed their emergency bags and slept in local school gymnasiums for the night.
The government also issued a very scary update regarding future risks. Officials warned the public that the chances of a megaquake striking the region have just risen significantly. Under normal conditions, the chance of a magnitude 8 or stronger earthquake striking the Japan Trench over 7 days is just 0.1 percent. Now, because of Monday’s event, that risk jumped up to exactly 1 percent for the upcoming week. A national security official begged citizens to prepare disaster kits, buy extra bottled water, and take serious steps to protect their own lives over the next few days.
The Japan Meteorological Agency released the exact scientific details of the big tremor shortly after it happened. The earthquake was recorded as having a strength of upper 5 on the Japanese seismic intensity scale. This specific level means the ground shakes so violently that normal people find it very hard to walk or stand up straight. The intense shaking also carries enough force to knock over old concrete block walls that lack proper steel reinforcement. Scientists pinpointed the exact center of the quake in the Pacific Ocean at a depth of exactly 20 kilometers below the ocean floor.
Japan deals with these terrifying natural disasters all the time. The country sits directly on top of the Ring of Fire, a massive circle of active volcanoes and deep oceanic trenches that surrounds the Pacific Basin. Because of this dangerous geographic location, Japan experiences a noticeable earthquake almost every 5 minutes. The island nation accounts for roughly 20 percent of all global earthquakes measuring magnitude 6.0 or higher. The entire world still remembers the horrific 2011 disaster that triggered multiple meltdowns at a major Fukushima nuclear power plant.
Following this recent quake, government officials quickly checked the local nuclear facilities. They reported some very good news for the worried public. Right now, no energy companies operate active nuclear power plants in the affected northern areas. Both Hokkaido Electric Power Company and Tohoku Electric Power Company released official statements regarding their equipment. The companies confirmed that their engineers found exactly 0 abnormalities or broken pipes at their offline nuclear sites. The government plans to keep a close eye on the ocean and the deep fault lines as the 1-week megaquake warning period continues.
