‘Hin Nam-no’ who escaped to the East Sea… Why can't I feel relieved yet?

<Anchor>

This time, let's take a closer look at actions to reduce damage with a disaster prevention expert.

Lee Song-gyu, president of the Korea Association of Safety Professionals, is here.

[Lee Song-gyu/President of Korea Association of Safety Professionals: The east coast has gone out now, but not the whole, but the center of the typhoon.

So, since the radius of the center of the typhoon is now 400km, it can be said that 400km is still there.

Then, if you predict how long this 400km can escape, there is the wind speed of the storm now, but the speed of the storm's movement.

However, the speed of movement is about 40-50 km/h.

So, I can tell you that the typhoon will go away in about 10 hours from this time.

However, as time goes by, the speed of strong winds, the speed of the winds will decrease, but it should be kept in mind that any rainwater or such flooding may increase.]

[Lee Song-gyu / President of Korea Safety Experts Association: It is possible to predict that the most dangerous situation has occurred.

Because the wind is very strong right now, even if all preparations were made, there was a fire like this accident because some electrical equipment was shorted by the wind and there were flammable substances around it.

If you look at the news, it is now called an energy storage device, but when we talk about the energy storage device, you can think of it as a large battery.

So the fire could have gotten bigger and it could be predicted what a dangerous situation it was.]

[Lee Song-gyu/President of Korea Association of Safety Professionals: Now, this time, a typhoon came along with a heavy rain and flooded it, but didn't it rain now a month ago last time?

The rain is making some landslides or floods more dangerous this time around.

Because in general, the land is a mountain, but the land absorbs water to some extent.

However, it can be said that this situation occurred because the water saturation level reached the saturation state and limit because it absorbed water last time, and it could not absorb any more, and such water overflowed as it passed into a certain river or such a reservoir.]

[Lee Song-gyu / President of Korea Safety Experts Association: Right now, the typhoon has gone out in the east coast area, but it is very important after the typhoon escaped.

The reason the typhoon escaped is mainly because of the swell waves in the accident.

So, the swell wave occurred a lot after three or four hours after the typhoon passed.

We call it a swell wave, because this swell wave is caused by the high high pressure surrounding a part of the swell wave because the atmospheric pressure is low in that part.

The rise of this wave concept comes locally as it is being washed away by the surrounding waves, to the shore.

So, if there were any people there, it is a very dangerous situation that can cause serious injuries and drowning, so even if a typhoon has passed, I think you should be careful at the beach or something like this today.]

[Lee Song-gyu/President of Korea Safety Experts Association: As expected now, when I checked the high tide in Busan, it was exactly 4:31.

But now, if we had followed yesterday's forecast, it was 6 o'clock, but it was pulled a little further, so there was still a bit of time at 5 o'clock, but since such high tide times overlapped, more damage is expected. Let's try it.]

[Lee Song-gyu / President of Korea Association of Safety Professionals: Now, the typhoon has passed, but the water that collects in the river may increase.

Although the wind speed can be lowered.

As for why the increase is more, if the water coming down from the upper part overflows, it can be a considerable amount.

Also, I can say that it is a very dangerous situation from now on because there are many rivers and reservoirs at the end as we descend from the top and the mountain.]

[Lee Song-gyu/President of Korea Association of Safety Experts: Right now, when there was a surprise heavy rain in Seoul before this, didn't the vehicle flood a lot?

But when we drive, mainly now at intersections, the flooded area is a bit low, so water accumulates a lot.

However, the car has already entered, but the water is filling up, so the driver is in trouble here.

The biggest reason we usually make a mistake while thinking about whether to go back or not is because sunk costs can lead to a bigger accident while working.

So, if you go to a vehicle and meet a flooded area, turn right away and make a U-turn again and come back. Otherwise, you have to park your car next to it and evacuate.

Especially now, there may be elderly people or such people in the car.

If there are such people, it is absolutely necessary to evacuate faster than usual.]
