Tsunami warning issued as 7.6 magnitude earthquake hits Japan

A warning about a tsunami has been issued by Japan following a number of powerful earthquakes.

Ishikawa and the surrounding places have experienced earthquakes. The Japan Meteorological Agency has indicated that one of the earthquakes had an initial magnitude of 7.6.

There are accounts of individuals stuck beneath the debris of structures that have crumbled, and a great number of residences are currently devoid of electricity. The public is advised to relocate to elevated areas as there is an impending danger of a tsunami.

The most recent update on the earthquake in Japan warns of an imminent and significant tsunami. Authorities are advising residents to leave the area immediately to ensure their safety.

A caution message about a possible tsunami was issued for Ishikawa and surrounding areas, while the western coastline of Honshu has received lesser cautionary alerts.

According to a representative from the meteorological agency, Noto in Ishikawa was hit by a tsunami that was more than 1.2 meters tall.

Officials advised against returning to areas affected by the recent powerful earthquakes for at least a week, warning of potential fires, house collapses, and landslides. They emphasized the danger and urged people to prioritize safety above all else.

according to the weather forecast, waves that can reach up to 5 meters high are anticipated.

Japanese media NHK has forecast waves of up to 5 meters in height. They have advised individuals to evacuate immediately to higher elevations or the rooftops of neighboring structures.

The region received a warning that tsunami waves may continue to appear and additional powerful earthquakes may happen in the vicinity in the next few days. Several after-effects were experienced in the area.

People living in the area are being advised to leave immediately.

The leader of Japan, Fumio Kishida, advised the people who might be affected by the tsunami due to the earthquake to leave the area without delay.

The individuals who live in the affected regions should be vigilant for any more potential earthquakes. Also, those who are in the areas that are likely to experience tsunamis must leave their homes immediately, according to his suggestion.

Yoshimasa Hayashi, representative of the government, stated that it is imperative for individuals residing in coastal zones to evacuate in the face of the approaching tsunami.

"It is crucial to act now. Please move to a secure location without delay," he urged.

There have been no anomalous events documented in nuclear plants.

The Nuclear Regulation Authority of Japan has stated that there were no abnormalities reported by any nuclear power stations in the vicinity.

Hokuriku Electric Power reported that over 36,000 homes in Ishikawa and Toyama prefectures experienced a power outage.

The train services that operate at a fast pace, to reach Ishikawa, are currently not available. Also, flights operated by Japanese airline ANA that were supposed to land at airports in Toyama and Ishikawa, have been redirected back. At the same time, Japan Airlines has cancelled the majority of its services that were scheduled to operate in the Niigata and Ishikawa areas.

Japan does not gamble when it comes to the potential danger of tsunamis.

If you think about the Tohoku earthquake that happened in 2011, you can easily understand why Japan is extremely cautious when it comes to the possibility of tsunamis.

The earthquake that occurred on the eastern coast of Japan resulted in waves as high as 40 meters which led to the unfortunate demise of around 20,000 individuals and forced another 200,000 people to leave their homes.

The earthquake and resulting tsunami that have occurred are not nearly as large as those in the past. It measured a magnitude of 7.6, which means it released considerably less energy than the 2011 earthquake - only about 250 times less.

However, this does not imply that Japanese authorities' sudden call for the evacuation of shorelines is inappropriate.

The earthquake is still a significant event, and it was not deep underground, only 10km, so a large portion of the energy was released at the Earth's surface. The epicenter was also located near the coast, which increases the likelihood of tsunamis.

This is the initial instance where Japanese officials offered a "major tsunami warning" - signifying a threat of waves reaching three meters or higher - since the 2011 earthquake. Afterwards, the warning was adjusted to a regular tsunami warning.

Powerful earthquakes on the western coast of Japan don't happen as often, but they are not impossible.

The earthquake that happened in 1993 in Okushiri had comparable magnitude and depth to the current one, and it resulted in a catastrophic tidal wave that took the lives of 230 individuals.

The unpredictable nature of the tsunami risk is due to the location of these earthquakes. The Sea of Japan is a smaller and more enclosed ocean, unlike the large Pacific ocean that sits to the west of Japan.

Tidal waves produced by a tsunami have the ability to reverberate and be redirected by the nearby shorelines and isles. This can sometimes result in even bigger waves compared to the ones created by the initial earthquake.

Yet, the reality remains that this earthquake was not as strong as the ones that hit in 2011 or the devastating tsunami on Boxing Day in 2004. Hence, it is improbable that there will be severe consequences outside of the eastern coast of Japan.

A tsunami has the potential to continue for several days.

According to Mohammad Heidarzadeh, the secretary general of the Joint Tsunami Commission, the tsunami may occur for two consecutive days, as the natural disaster has the potential to produce "persistent oscillations" due to its location in the Sea of Japan, which is almost a completely enclosed basin. This expert shared the information with Sky News.

According to an expert, the situation indicates that over the course of two days, there may be huge waves that can affect countries situated on the opposite side like North Korea, South Korea, and Russia. This can be just the start of a calamity, in my opinion.

Russia and North Korea have released alerts about tsunamis.

Russia has alerted residents of the western coast of Sakhalin island and the nearby cities of Vladivostok and Nakhodka on the eastern side of Russia, near Japan, about the risk of a tsunami. Additionally, North Korea has also issued a warning of possible tsunamis in its east coast regions.

According to South Korea's weather organization, there is a possibility that the sea level in certain regions of the east coast could increase following the earthquake.

Japan is highly susceptible to earthquakes. In the month of March, 2011, a big earthquake hit and a tsunami followed which led to nuclear plant meltdowns at Fukushima.
