No tsunami threat to Hawaii after 2 big quakes off Russian Federation

A 7.7 magnitude natural disaster struck Monday evening off Russia’s Kamchatka Peninsula.The epicenter of the magnitude-7.7 natural disaster was located about 123 miles (199 km) east-southeast of Nikol’skoye, Russia, according to the USGS.Magnitudes between 6.5 and 7.5Earthquakes of this size do not usually produce destructive tsunamis.It was also very shallow, only 10km below the seabed, which would have amplified its effect, but it was far from any mainland.It sparked a tsunami warning from the Pacific Tsunami Warning Centre.”Based on preliminary quake parameters. hazardous tsunami waves are possible for coasts located within 300 km (186 miles) of the natural disaster epicenter”, the center wrote in an official message.Waves had been initially forecast to be less than 0.3 meters (1 foot) above the tide level for coasts in the area ranging from Russian Federation to Hawaii, the tsunami authority said. There was also no tsunami warning for the South Pacific.It was followed by several aftershocks, including a couple above a magnitude of 5.0.
