On Friday, a powerful magnitude 7.0 earthquake struck near Vilyuchinsk in Russia's Kamchatka Peninsula. The European-Mediterranean Seismological Centre confirmed the intensity, and thankfully, no tsunami warning was issued. However, Japan mistakenly released a startling warning for a 9.9 magnitude quake shortly after, despite history showing only five quakes of magnitude 9 or higher have been documented. Notably, a magnitude 10 quake is deemed impossible based on current geological understanding.
