Was there an earthquake just now in Japan? Yes there, was.At around 11:36 pm on the 16th, there was an earthquake observing a maximum seismic intensity of 6 uppers in Miyagi and Fukushima prefectures. The epicenter is off the coast of Fukushima prefecture (latitude 37.7 degrees north, longitude 141.7 degrees east), the depth of the epicenter is about 60 km, and the magnitude of the earthquake is estimated to be 7.3. This earthquake may cause a tsunami. Please check the tsunami information for details.According to the Japan Meteorological Agency, the depth of the epicenter is estimated to be about 60 km, and the magnitude indicating the magnitude of the earthquake is estimated to be 7.3. The agency issued a tsunami warning to both prefectures in anticipation of a 1-meter tsunami at a high place. The agency is calling on people not to enter the sea or approach the coast until the warning is lifted.

Is 7.3 earthquake strong?

According to the Richter magnitude scale from Wikipedia, 7.3 Richter of earthquake falls on the bottom and describes as a Major damage earthquake.

Most buildings are damaged, with some partially or totally collapsing or receiving serious damage. Structures that are well-designed are more likely to sustain harm. Felt over long distances, with serious damage primarily confined to a radius of 250 kilometers from the epicentre.

An earthquake of 7.3 occurs about 10 to 20 per year.

Magnitude	Description	Earthquake effects	Frequency of occurrence
1.0–1.9	Micro	Microearthquakes, not felt, rare.	Continual/several million per year
2.0–2.9	Minor	Felt slightly by some people.	Over one million per year
3.0–3.9	Minor	Felt by people, Very rarely causes damage.	Over 100,000 per year
4.0–4.9	Light	Noticeable shaking of indoor objects and rattling noises.	10,000 to 15,000 per year
5.0–5.9	Moderate	Can cause damage of varying severity to poorly constructed buildings.	1,000 to 1,500 per year
6.0–6.9	Strong	Damage to a moderate number of well-built structures in populated areas.	100 to 150 per year
7.0–7.9	Major	Causes damage to most buildings, some to partially or completely collapse or receive severe damage.	10 to 20 per year
8.0–8.9	Great	Major damage to buildings, structures is likely to be destroyed.	One per year
9.0 and greater	Great	At or near total destruction – severe damage or collapse to all buildings.	One per 10 to 50 years

Is it related to the Fukushima-ken-Oki earthquake in February last year?

Internal destruction of the plate on the seaside, “earthquake in the slab”. Is it related to the Fukushima-ken-Oki earthquake in February last year?

Regarding the mechanism of the earthquake that caused strong tremors in the Tohoku region, experts point out that it is highly possible that an “intraslab earthquake” occurred in which the inside of the plate (rock plate) on the seaside was destroyed.

According to Professor Shinji Toda (Seismology) of Tohoku University, while intraslab earthquakes occur deep underground, the period of seismic waves is short and strong shaking is easily observed. This time, because the epicenter was close to the land area, it seems that the shaking increased over a wide area in Tohoku and Kanto.

In addition, Professor Toda believes that the location of this earthquake is closely related to the earthquake with a maximum seismic intensity of 6 or higher that occurred off the coast of Fukushima Prefecture in February last year.

According to Professor Koshun Yamaoka (Seismology) of Nagoya University, the epicenter of this earthquake is included in the epicenter area of the Great East Japan Earthquake in March 2011, and it occurs in the area where seismic activity is active even after the earthquake. rice field. It is said that it is considered to be a type of earthquake called “reverse fault type” in which the faults shift vertically due to the force of pushing each other.

Naoshi Hirata, Professor Emeritus of the University of Tokyo (Seismology) said, “After a big earthquake, there is a possibility that an earthquake of the same degree of strong shaking will occur again. If you live in a house that is not earthquake-resistant, I want you to evacuate to a safe place. ”
