DAMAGES DUE TO LIGHTNING STRIKE

LIGHTNING SAFETY RULES (INDOORS)

STAY AWAY FROM ELECTRICAL SOCKETS, APPLIANCES, TELEVISION AND TELEPHONES; SHUT-OFF THE MAIN POWER SWITCH. STAY AWAY FROM WINDOWS, WATER FAUCETS, PIPES AND ELECTRICAL OUTLETS.

LIGHTNING SAFETY RULES (OUTDOORS) BE ALERT OF THE SIGNS OF THE IMPENDING STORM GET AWAY FROM TREES OR TALL OBJECTS. STAY AWAY FROM HILLTOPS, BENCHES AND OPEN FIELDS AND SEEK SHELTER IN A LOW LYING AREA SUCH AS A DITCH OR RAVINE. IF YOU ARE WITH OTHER PEOPLE, SPREAD OUT. STAY AWAY FROM WATER OR WET AREAS.

WHAT TO DO IF THERE IS NO Lightning experts invented SHELTERsafety AND YOU AREhave CAUGHT IN A a "lightning safety position" that is very THUNDERSTORM?

important to know if you are caught in a thunder storm and you can't find a shelter. This position looks hard, but it could save your life. There are several reasons for doing it.  It makes you a smaller target.  With your heels together, if lightning hits

the ground, it goes through the closest foot, up to your heel and then transfers to the other foot and goes back to the ground again. If you don't put your feet together, lightning could go through your heart and kill you.  You put your hands over your ears to protect them from thunder.

Climate change. The earth’s temperature is rising because the heat emitted by the sun is trapped by greenhouse gases (carbon dioxide and other gases) in the atmosphere. The higher temperature is melting the polar ice caps, causing more water to evaporate. The atmosphere becomes soaked with moisture. More moisture in the clouds equals heavier rains.

The Greenhouse Effect

Greenhouse gases (GHGs) trap heat from the sun to keep the Earth warm.

With the ice caps melting, more water is poured into the oceans, thus raising their levels. The seas invade low-lying areas. If the melting of the ice does not stop, low-lying islands will disappear; the bigger ones will have their areas reduced as the seas invade their shores.

Sea Level Rise Projections Sea level rises caused by water expansion due to warming of oceans, and melting of glaciers and ice sheets are projected to increase by 18 to 59 centimetres by 2100.

2rd Factor Illegal logging,

Greedy loggers have ravaged our forests and most of our mountains are now bald. Without trees, there are no roots to hold the soil together. Thus, rainwater easily erodes the mountainsides, carrying the topsoil down to the streams and rivers below.

As the water flows down the waterways, it drops the silt it is carrying. Over the years, this silt has made the waterways shallower so that they can hold less and less water. They therefore easily overflow their banks.

Floodwaters are now brown, unlike before when they were clearer and cleaner. That is because of the silt they are carrying. When the floods recede, they leave a thick layer of mud. That is also the mud that they deposit at the bottom of the waterways.

3rd Factor Rapid Urbanization

With the development of more housing subdivisions on what were once rice fields, the construction of more office buildings, shopping malls and residential condominiums in the cities, and the paving of more streets and parking lots, a layer of nonporous concrete covers bigger and bigger parts of the land. Thus, rain and floodwaters cannot pierce this layer to seep through the ground and into the underground aquifers as they used to do. They have to stay atop all that concrete. The result: floods.

4th Factor Inadequate drainage system. The planners did not anticipate the big volumes of water that would inundate the land. The drainage system, therefore, cannot drain the rain and floodwaters fast enough.

The fifth factor is GARBAGE specifically the bad habit of many Filipinos to throw their trash anywhere, and especially into waterways.

What can we do to improve the situation? 1. Reduce all forms of burning so that the emission of greenhouse gases is reduced, and stop or slow down the rise in the earth’s temperature. That will help stop or slow down the melting of the polar ice caps and the rising levels of the oceans. 2. Motor vehicles, power plants, factories burning coal, and planters burning huge tracts of the Amazon rainforest are the worst polluters of the earth’s atmosphere. 3. Leave more areas open to agriculture, parks, backyard gardens, and other open spaces to leave rainwater more room to seep into the ground.

4. Stop all logging, legal and illegal, as well as charcoalmaking. Charcoal makers cut even small trees. Dredge waterways and lakes. 5. Unclog drainage pipes and keep them clear of garbage. Improve the drainage system. 6. Be good citizens and always follow laws.

P. S. things to remember…

Building Resilience (flexible) always involves taking some risks….

Resilience reduces the burden placed on governments

Resilience requires Creative Innovation

Building Resilience can feel a bit like this….

but when the task is shared it is realisable
