- 7.3 Magnitude Quake Hits North Japan, Tsunami Alert Issued
The tsunami advisory was made for Fukushima and Miyagi prefectures in eastern Japan following the quake that had a preliminary epicenter depth of 60 kilometers (37 miles), according to the Japan Meteorological Agency.
The advisory warns of tsunami heights reaching up to 1 meter above normal tidal levels, with the initial waves reaching shore around midnight local time (11 a.m. ET).
I would consider that a moderate depth, but perhaps enough to mitigate a tsunami. Of course, it all depends on how and how much of the ocean floor and volume of ocean water is displaced.Baluncore said:Those earthquakes are very deep.
Maybe they are aftershocks of the big tsunami earthquake.
A 7.3 magnitude earthquake is considered a major earthquake and can cause significant damage and destruction. It is 10 times more powerful than a 6.3 magnitude earthquake and 100 times more powerful than a 5.3 magnitude earthquake.
The earthquake hit off the coast of Miyagi prefecture in North Japan, approximately 60 kilometers southeast of the city of Sendai.
Yes, a tsunami warning was issued for the coastal areas of Miyagi prefecture and surrounding areas. However, it was later cancelled as the tsunami waves were not as high as initially predicted.
Japan experiences frequent earthquakes due to its location on the Pacific Ring of Fire. However, earthquakes of this magnitude (7.3) are less common and occur every few years.
After a 7.3 magnitude earthquake, it is important to stay alert for aftershocks, as they can cause additional damage. People should also be aware of any potential tsunami warnings and evacuate to higher ground if necessary. It is also important to check for any injuries or damage and follow any instructions from local authorities.
