At 11:23hrs UTC (6:23 am) a strong magnitude 5.9 #earthquake occurred offshore Japan – causing light shaking in the capital, Tokyo. The event, with a focal depth of 40kms, is located 2500+km South of the July 6, 2018 M6.0 Yuhzno, Russia earthquake. Station E1TX is about 96 polar degrees away from the epicenter which is on the cusp of the “#seismic shadow zone” where seismic wave phases are limited / not detected due to the presence of Earth’s liquid outer core. The P wave, or body wave, is highlighted by a yellow circle on the seismogram recorded by the Raspberry Shake #raspishake #Weston_Quakes
As noted before, earthquakes are not un-common for the region located near the Kuril Islands and #Kuril Trench. Most importantly, no damaging ground shaking was detected near nuclear facilities. Minimal personal damages were reported in the Chiba region. No tsunami warning was issued. Read more, HERE.
