Typhoon 10 was said to be the strongest class in history. Although it was less powerful than expected when it actually got close, it came close like a very strong typhoon.

I will summarize the damage caused by Typhoon No. 10.

Not only in Kyushu (mainly Nagasaki and Saga), where the typhoon was near, but also in Yamaguchi prefecture, the percentage of “storms that have never been experienced” is high.

In the damage report that reached Weather News, it was reported that there was actual damage in the area where the percentage of respondents who responded “a storm they have never experienced” was high.

It can be seen that the winds are strong in the Nagasaki and Saga prefectures, which are close to the typhoon, and that the damage is mainly occurring off the coasts of the Kochi, Kagoshima and Miyazaki prefectures, where the south wind is blowing.

▼ Maximum instantaneous wind speed [6日(日)〜7日(月)10時まで]1st place Nomozaki (Nagasaki Prefecture) 59.4 m / s
2nd place South Daitojima (Okinawa Prefecture) 50.7 m / s
3rd place Pumpkin (Nagasaki) 48.9 m / s
Saga (Saga Prefecture) 41.6 m / s
Sasebo (Nagasaki Prefecture) 41.6 m / s

In the investigation into the damage caused by the power outage, there are reports that “there was a complete power outage” in Yamaguchi prefecture. It is thought to have been caused by the wind that blew into the Bungo Canal, and it is clear that the topographical effects cannot be ignored.

There are no reports of dreaded first-class river flooding or large-scale flood damage. However, it has been raining almost 500mm in 24 hours, so the amount of rain cannot be said to have been small. Since Miyazaki and Kochi, which are resistant to rain, were the main areas, it can be said that the damage itself was less.

▼ 24 hour rain [6日(日)〜7日(月)6時までの最大値]1st place Shinmon (Miyazaki) 522.5mm
2nd place Ebino (Miyazaki) 477.5mm
3rd place Shiiba (Miyazaki) 439.0 mm

■ Typhoon power has fallen
The eyes of the typhoon traveling over the southern seas of Japan collapsed, and the power was cut off once due to doubling. After that, the temperature of the sea water in the sea near Kyushu, which is the course of the typhoon, became lower than expected, so the strength of the typhoon at the time of approach was lower than expected. initially. Therefore, it is presumed that the impact was suppressed.

■ The river did not overflow
As of the day before the approach, there were concerns about first-class river flooding and there were concerns about flood damage. However, due to the results of the measures taken by the social infrastructure, such as the anticipated discharge of dams, the flooding of the river did not occur.

■ Knowledge of measures and evacuation
Although it was weaker than expected, it was a typhoon with an instantaneous maximum wind speed of 60m / s and 945hPa as it approached, which could cause a lot of damage. However, the reason damage is minimized is thought to be that the entire society was able to take action and prepare for evacuation in advance.

Learning from past disasters and connecting them to the future can be the ideal form of disaster mitigation.

Another reason for the lesser damage was that the typhoon was approaching in the middle of the night and not during many people’s life hours.

Weather News is working to request real-time rain conditions, disasters caused by heavy rain, traffic and the impact on people’s lives on Twitter to reduce the number of people affected by heavy rain. The information is simply added by adding “#disaster mitigation report” to the tweet, and it is helpful for understanding the current situation and making preparedness decisions.
