The Big Three - Sheltering (Part 2)


In the preceding post we saw the importance of sheltering in the case of rain and how annoying it could be to be unprotected under pouring water, even to the point of danger.

However dangerous it could be, one scenario is worse than rain falling on you, it is wind and rain together striking you. In that combination, wind is the worst as it gives more energy and velocity to the rain drops falling on you. And the stronger the wind, the stronger the drops to the point of being extremely painful when it hits you.

But wind is a danger by itself, even without rain. Depending on the strength it could help refresh you on a hot summer day or making debris flying around and kill you. Most of the time, wind is quite innocuous, even welcomed - especially in countries like the Philippines or Indonesia where heat is potent.

However, in the region of the West-Pacific there is also another kind of wind occurrences which is way less pleasant - Typhoons (or Hurricanes, or Cyclones - different regional name for the same kind of disastrous storm). You see, behind typhoons lies one of the worst natural weapon the Earth is capable of - Wind.

We are not speaking here of a refreshing breeze, but about an atmospheric system the size of a country with wind which could go to 325 km/h (200mph) like the late Hurricane Patricia who, on October 23, 2015, made landfall in Mexico. It was the strongest wind recorded in a hurricanes, even Super-Typhoon Hayian (Yolanda) did not reach that wind intensity with its 230km/h.

Those kind of speed are the one you find in intense tornadoes. Well, imagine a tornado the size of a country and you have a good idea of what a typhoon (hurricane, cyclone) can be. Either it could be seen as a humongous vacuum cleaner or a wind Karsher, but in every cases, nearly nothing stand.


Before & After Super-Typhoon Hayian (Yolanda) - Philippines 2013

When a typhoon strikes you have to be in a shelter at all cost. The wind referred to above not only are destructive, but they transform any debris in a powerful weapon that will kill you. In some instances debris could have so much energy that it could even pierce a brick wall or a tree trunk, what do you think it could do to your body?

Whether you have 100 liters of water or 300 tons of food in store for emergency, if you are not protected from something like typhoons it will not serve you well because everything would fly around, not speaking about you being wounded or killed. So a shelter is extremely important.


Take the time to think about one of the first thing they do in disasters relief management is to build fast shelter for people? Because you need to be protected from the elements, it is vital for the welfare of people. We all need to feel secured, but it is never as true as in a disaster zone where people lost everything except their own life.

Whether you live in the West-Pacific or anywhere in the world for that matter, wind could become a serious danger if you are not able to protect yourself. A good shelter is a basic requirement to protect you and your family from the effects of the wind.

Next time we will see another good reason to have a shelter, and it has to do with Heat.

Until next post, Mabuhay!
