長野ながの県けんで震度しんど5弱じゃく 1週間しゅうかんほど同どう程度ていどの地震じしんに注意ちゅうい

On the night of the 18th, an earthquake with its epicenter in the northern part of Nagano Prefecture occurred, and a maximum seismic intensity of lower 5 was observed in Nagano Prefecture.

The Japan Meteorological Agency is urging caution, stating that in the past, large earthquakes that occurred in shallow inland areas, including this region, have been followed by earthquakes of similar magnitude within about a week.

Around 8 PM on the 18th, a magnitude 5 earthquake with a depth of 13 kilometers struck in the northern part of Nagano Prefecture.

There was an earthquake of magnitude 1.

In this earthquake, a maximum seismic intensity of lower 5 was observed in Omachi City, Ogawa Village, and Chikuhoku Village in Nagano Prefecture, and tremors ranging from intensity 4 to 1 were observed over a wide area from the Kanto to Kinki regions.

According to the Japan Meteorological Agency, the observation of a seismic intensity of lower 5 in Nagano Prefecture is since the Noto Peninsula earthquake on New Years Day last year.

In the northern part of Nagano Prefecture, seismic activity has become active, and in the early hours of the 19th, a magnitude 4...

As of 4 a.m. on the 19th, a total of 43 earthquakes with a seismic intensity of 1 or higher have been observed, including one earthquake with a maximum intensity of 4.

The Japan Meteorological Agency is urging caution in areas where the shaking was strong during this earthquake, as there is a risk of rockfalls and landslides.

Additionally, in the past, large earthquakes that occurred in shallow inland areas, including this region, have been followed by earthquakes of similar magnitude within about a week. Therefore, caution is advised for earthquakes with a maximum intensity of around 5 lower in the next week, and there is also a warning for the possibility of even stronger earthquakes.

Railways and Highways Operating Normally According to JR East, the Shinkansen and conventional lines in Nagano Prefecture have been operating normally since the first train on the 19th.

According to the Japan Road Traffic Information Center, there are no road closures due to the earthquake on the expressways in Nagano Prefecture.

19th Ohayou Nippon Live Broadcast: No reports of injuries or building damage as of 11 PM on the 18th According to the police and fire department, as of 11 PM on the 18th, there have been no reports of injuries or building damage in Omachi City, Chikuhoku Village, and Ogawa Village, where a seismic intensity of lower 5 was observed.

According to the prefecture, there is no information about injuries or damage in other municipalities as well.

Omachi City No injuries confirmed In Omachi City, Nagano Prefecture, where a seismic intensity of lower 5 was observed, the mayor and city officials held a countermeasure meeting from around 10 p.m. on the 18th.

At the moment, there have been no reports of injuries, but it has been reported that stones on the slope beside a city road in the Yasaka area of Omachi City have collapsed.

After the meeting, Mayor Tetsu Ushikoshi stated, There is no noticeable damage at this point, but we want to gather information again by the morning of the 19th, and urged citizens to be cautious of future earthquakes.

Expert: Relatively Active Region According to Professor Shinichi Sakai of the University of Tokyo, who is knowledgeable about seismic activity, the northern part of Nagano Prefecture, where the epicenter was located this time, is a relatively active seismic region, with magnitude 5 class earthquakes occurring approximately once every few years.

Magnitude 6 in 2014

In addition to observing a seismic intensity of lower 6 in Nagano City and other areas with a magnitude 7 earthquake, in 2018, a magnitude 5...

An earthquake of magnitude 2 has occurred, and a seismic intensity of upper 5 has been observed in Sakae Village, Nagano Prefecture.

Regarding the recent earthquake, Professor Sakai stated, Since the epicenter is shallow, it is possible that strong shaking was felt locally.

There is also a risk of landslides and water pipe bursts, it says, urging caution.

According to the governments Earthquake Research Committee, there is the Itoigawa-Shizuoka Tectonic Line Fault Zone, one of the largest in the country, near the epicenter.

The Itoigawa-Shizuoka Tectonic Line Fault Zone is divided into four sections, and the one near the epicenter this time is the northern section.

Magnitude 6 that occurred in November 2014

It is believed that a part of the Kamishiro Fault in this section shifted during the magnitude 7 earthquake, and a maximum seismic intensity of lower 6 was observed in Nagano City and other areas, resulting in multiple injuries and damage to buildings.

In the northern section of the Itoigawa-Shizuoka Tectonic Line Fault Zone, the urgency of an earthquake of magnitude 7 class occurring within the next 30 years is rated as the highest S rank.

According to an official from the Omachi City Hall, where a seismic intensity of lower 5 was observed, there was a strong horizontal shaking that lasted for several tens of seconds, but nothing fell from the shelves.

[Chikuhoku Village Office Staff] According to the staff at the Chikuhoku Village Office, where a seismic intensity of lower 5 was observed, there was a large jolt that felt like it was pushing up from below for several seconds, but nothing fell from the shelves.

[Ogawa Village Office Staff] According to the staff at the Ogawa Village office, where a seismic intensity of lower 5 was observed, there was a vertical shaking that felt like a thrust from below for a few seconds.

There is no damage such as items falling from shelves or glass breaking, and water and electricity are available at the town hall.

Seismic intensity 4 At the NHK Nagano Broadcasting Station located in Nagano City, where a seismic intensity of 4 was observed, there was a small horizontal shaking, described as rattling, that lasted for a few seconds on the basement floor.

According to the Japan Meteorological Agency, the last time an intensity of lower 5 was observed in Nagano Prefecture was during the Noto Peninsula earthquake that occurred on New Years Day last year.

Additionally, the earthquake originating in the northern part of Nagano Prefecture, where a seismic intensity of 5 lower or more was observed, occurred on May 25, 2018, with a magnitude of 5.

Since the earthquake of magnitude 2, a maximum seismic intensity of 5+ was observed at that time.

注意 points for earthquakes at night According to the Japan Meteorological Agency, with a shaking intensity of around 5 lower, there is a risk of dishes and books on shelves falling and unstable furniture toppling over.

It is difficult to understand the surrounding situation in the dark hours.

There is also the possibility of being hit by strong shaking again.

Instead of acting recklessly, prioritize your safety by waiting until it gets light to start cleaning up.

Please make sure to rest with slippers or shoes to wear when moving, a flashlight, and an emergency grab bag by your bedside so you can evacuate quickly tonight.

Also, to ensure safety even if a strong tremor occurs while sleeping, please check that furniture will not topple over, heavy objects will not fall, and that unstable items are not near entrances or passageways.
