Training assuming the third day after the Tokyo Metropolitan Earthquake September 2, 17:36, Toshima-ku, Tokyo

The “Tokyo Metropolitan Earthquake” is predicted to occur with a probability of 70% within the next 30 years. In the worst case, there are estimated to be 23,000 dead and up to 7.2 million evacuees. For this reason, the National Central Disaster Prevention Council says it is necessary to give priority to rescue operations for about three days after the earthquake. Under such circumstances, recovery of infrastructure related to daily life such as water and electricity is expected to take much longer, and local governments are required to take concrete measures to protect the lives of residents. We interviewed Toshima-ku, Tokyo.

On the 2nd, more than 100 people, including ward staff, police and the Self-Defense Forces, participated in the illustrated training held at the Toshima Ward Office in Tokyo.

The training was conducted on the assumption that the earthquake occurred directly below the Tokyo metropolitan area in the northern part of Tokyo Bay.

In this training, the tasks to be dealt with for each task in charge were given regarding the situation after the third day when water and food stored in shelters and households were exhausted.

Of these, the Health and Welfare Department, which handles infants and the elderly, and persons with disabilities, plans how to transfer to nursing homes that can provide specialized support in the event of a disaster while grasping the situation of each victim. It was.

In addition, the general affairs department in charge of water supply has closed roads about how to pass around evacuation shelters and houses for over 60,000 residents who have suffered water outages. I was planning the operation of a truck with a water supply tank.

Currently, there are only two places in the ward where water can be injected into the water supply tank, and the ward is expected to be used at the discretion of the ward for the other 10 places managed by the city. I am training and would like to make adjustments with the Tokyo Metropolitan Government so that it can be operated flexibly in the event of a disaster.

The two-day training also raised issues for the future, such as sharing information with local welfare officers who are familiar with the elderly and people with disabilities when delivering water to victims.

“The city is making preparations and adjustments as the forefront for the residents, and I would like the residents to stock up the water and food for three days.” I think. ”

“Stockpile for 3 days”

In the event of an earthquake directly under the Tokyo metropolitan area, electricity, water and gas may become unusable for the time being. Therefore, in preparation for the stagnation of supplies in Tokyo, stockpiling is initially targeted for 3 days. I should do it.

When a couple, an infant, and a family of four elderly women are model cases, as a guideline for stockpiling for three days,
▽ 5kg of washed rice,
▽ 6 retort rice,
▽ 3 instant noodles,
▽ 1 cassette stove and 6 cassette gas cylinders,
▽ 2 boxes of powdered milk,
▽ We give diaper 1 pack.

In addition, it is said that drinking water needs 3 liters per person per day.

In order to store this stock, the Tokyo Metropolitan Government purchases a large amount of food and daily necessities used in daily life and keeps it at home, using it from items that have become old or near the expiration date, and replenish them accordingly. We recommend a method called “rolling stock” or “daily stockpile”.

Review of Tokyo's regional disaster prevention plan after 5 years

The Tokyo Metropolitan Area Disaster Prevention Plan will be reviewed for the first time in five years in July, taking into account the Tokyo Olympics and Paralympics of next year, and incorporating measures such as air conditioning and power sources for shelters based on lessons learned from the 2016 Kumamoto Earthquake. It was

The human damage assumed in the plan is the worst case when an earthquake directly below the Tokyo Metropolitan area occurs in the northern part of Tokyo Bay. In the worst case, approximately 9,700 people died and approximately 3.39 million evacuees occurred in Tokyo. Then it is expected.

As for the damage to lifelines such as energy and water, the water outage rate is expected to be about 35% and the power outage rate is expected to be about 18%.

The Tokyo Metropolitan Government has set a goal of reducing the earthquake resistance rate of housing to 95% by next year as a measure to reduce human damage.

We will also install support for installing air-conditioning facilities in gymnasiums, which serve as shelters, and install solar panels that can be used to charge smartphones as an emergency measure for lifelines.

Water supply in Toshima-ku's proprietary tank

Tokyo Toshima Ward has prepared a water tank that it has developed in order to quickly spread the water to the area that was cut off by the earthquake.

According to Tokyo's regional disaster prevention plan, when an earthquake directly below the Tokyo metropolitan area occurs in the northern part of Tokyo Bay, water damage will occur in about one-quarter of households in Toshima Ward, and restoration may take up to 30 days depending on the location. It is assumed.

Toshima Ward has the highest single-person household rate over 75 years old in the ward and city nationwide, and there are many narrow roads due to the denseness of old houses, so many residents cannot move to shelters or stay at home One of the challenges is how to distribute water to such places.

To cope with these challenges, Toshima Ward has developed a water tank that can hold 1000 liters of water together with the private sector. This water tank is foldable and has a bag shape with a small water surface area to increase the stability of the center of gravity. Two tanks can be placed on a 2-ton truck that can pass through a narrow road.

In addition, there are four water inlets, which are equipped with nozzles that can distribute water twice as fast as general water faucets.

In the training conducted by the ward disaster prevention officer on the 22nd of last month, in Nishi Ikebukuro Park designated as an emergency water supply facility at the time of the earthquake, the staff expanded the water supply tank folded from the water supply port to the tank The procedure for adding water was confirmed and the time taken was measured.

The driver of the local truck association that had an agreement at the time of the earthquake was transported to the junior high school in the evacuation center and actually distributed water to elementary school students and the elderly.

In the ward, 40 water tanks will be prepared, and 20 trucks will be secured by concluding a disaster agreement with local truck associations. We are preparing to distribute water.

Yuki Imaura, Crisis Management Director of Toshima Ward said, “If more than half of Tokyo is shut down, the city and the Self-Defense Force water trucks will not be able to handle it alone. I want to accumulate staff training such as assembling water tanks. "

Electric bus for sightseeing is also used as an emergency power source

In Toshima-ku, Tokyo, we are considering using an electric sightseeing tour bus as an emergency power source in the event of a disaster.

According to Tokyo's regional disaster prevention plan, if an earthquake directly below the Tokyo metropolitan area occurs in the northern part of Tokyo Bay, a power outage will occur in approximately one-tenth of Toshima Ward, and depending on the location, it may take up to a week for recovery. It has been.

The introduction of electric buses will begin in November, it plans to 10 units in prospect this year is deployed, as the tour bus for sightseeing during the day, when many supposed to be about half of this is around the root of the wards It is.

In the event of a disaster, you can head to a place where emergency power is needed, such as an evacuation center, charge 2,000 smartphones, and use it for lighting in case of triage to an injured person in front of an emergency medical rescue center. It is also being considered.

On the 23rd of last month, the disaster prevention officers in the city boarded the bus and measured the travel time from the planned excursion route to the elementary school, which is one of the shelters. We also confirmed the procedure for turning on the power from the bus and turning on the lights.

“The ward is at the forefront of disaster response, so I would like to examine various possibilities such as how to use the bus to protect the safety and security of the residents,” said Kazuya Hoshino, head of the disaster management section in Toshima Ward. It was.
