Japan was placed on high alert Sunday evening after a strong offshore earthquake shook the northern Pacific region, prompting a tsunami advisory for Iwate prefecture. The tremor struck at 5:03 pm local time, sending immediate concern across coastal communities long familiar with the destructive power of the sea.
Authorities said the quake originated in waters off Iwate, with initial readings estimating its magnitude between 6.6 and 6.8, depending on monitoring agencies. &ldquo;A tsunami advisory has been issued,&rdquo; the Japan Meteorological Agency announced, cautioning that waves up to one meter could reach the coastline &ldquo;at any moment.&rdquo;
&nbsp;Offshore tsunami waves had already been observed, urging residents to move away from beaches and low-lying areas. Live television images, however, showed relatively calm seas.
The fear is rooted in memory. The same coastline witnessed horrific devastation in 2011, when a 9.0 undersea earthquake unleashed a massive tsunami that killed nearly 18,500 people and triggered meltdowns at the Fukushima nuclear plant, one of the worst nuclear disasters in history.
Japan remains one of the world&rsquo;s most seismically active nations, lying atop four major tectonic plates along the Pacific &ldquo;Ring of Fire.&rdquo; The archipelago experiences around 1,500 earthquakes each year, though most cause limited damage.
As of now, no casualties or structural damage have been reported, but authorities remain on high alert, monitoring wave activity along the northeastern coast.
