A 7.0 earthquake hit off the coast of the Miyagi Prefecture, Japan, last night, 20 March 2021, at 6:09 pm local time. The quake occurred 16 km northeast of the city of Ishinomaki and hit at a depth of 54 km. Ishinomaki was one of the most affected cities during the 2011 Tohoku Earthquake and Tsunami.
Our monitoring service received multiple user reports describing moderate to strong shaking. Multiple users also reported to have felt about 20 seconds of shaking. The quake was felt at up to 350 km radius distance from the epicenter. It reached the cities of Tokyo and Yokohama where a great number of user reports also came from. Japan's Meteorological Agency reported an intensity of 5 for the Miyagi Prefecture, and an intensity of 3 for the cities of Tokyo and Yokohama.

A tsunami warning was issued following the 7.0 quake. NHK reported waves of up to 1 meter that hit land shortly after the quake. Due to this warning, the town of Watari in the Miyagi Prefecture issued evacuation orders for about 7,000 of their residents. This warning was downgraded to a “tsunami forecast” of slight changes in sea level along the Japan eastern coast by 7:30 pm local time. The US tsunami warning system stated that there was no threat of tsunami from the earthquake.
The Miyagi Prefecture fire department reported no significant damage. According to the Japan Times, no abnormalities were detected from the nuclear reactors in the eastern and northeastern parts of the country. There have also been at least 2 reported injuries. Meanwhile, 200 homes in Kurihara in the prefecture were without electricity according to the NHK. Rail line services were also halted including the Tohoku Shinkansen (bullet train).

This quake came just a few days after the region marked the 10th year anniversary of the 2011 Tohoku quake and tsunami, the Japan Times noted. Over a month prior to this quake, a strong quake also hit off the neighboring Fukushima Prefecture. Seismologists believed that the February 2021 quake was an aftershock of the 2011 megaquake.
Japan is on the Pacific Rim of Fire, a large region where most of the volcanic and seismic activities in the world occur. This region sits along the rim of the Pacific Plate which undergoes subduction under the other surrounding plates.

Magnitude 6.9 earthquake strikes near Ishinomaki, Ishinomaki Shi, Miyagi, Japan
6.9 quake 20 Mar 6:09 pm (GMT +9)
6.9 quake 20 Mar 6:09 pm (GMT +9)
Just 11 minutes ago, a 6.9-magnitude earthquake struck near Ishinomaki, Ishinomaki Shi, Miyagi, Japan. The tremor was recorded early evening on Saturday 20 March 2021 at 6:09 pm local time, at an intermediate depth of 73 km below the surface.
The event was filed by the German Research Centre for Geosciences (GFZ), the first seismological agency to report it.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 6.9 earthquake as well.
Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Moderate shaking probably occurred in Ishinomaki (pop. 117,200) located 50 km from the epicenter, Yamoto (pop. 32,000) 57 km away, Ōfunato (pop. 35,400) 68 km away, Shiogama (pop. 59,500) 75 km away, Furukawa (pop. 76,300) 80 km away, Ichinoseki (pop. 63,000) 81 km away, Sendai (pop. 1,063,100) 90 km away, and Mizusawa (pop. 61,300) 98 km away.
