Lightening is one of the fearful natural phenomenon. During this last decade, the fear of lightening strikes is a big concern for many people in concluding Cambodians. Last year, more than 100 people were killed and injured. Life is so fragile and the mother nature seems to be so cruel to mankind.

Why is there lightening strike? What are the causes of the strikes? And how to prevent ourselves from it?

Last week, I sent an email to the Radio Free Asia Khmer Service to request if they can invite an expert on the Lightening Strike to talk a bit more so that the people will be alerted and understood more about this natural phenomena. Luckily, The RFA CAll In Show this Friday 10th July 2009, will discuss about Lightening Strike. If you have any questions, please contact RFA via khmer@rfa.org

There is also a similar case of lightening strikes in Thailand. The following is the report from the Nation.

Officials raise fear of lightning strikes

Experts are warning people how to avoid lightning strikes, which have increased to 100,000 occurrences a month.

The Electricity Generating Authority of Thailand (Egat) says at least 1.3 million lightning strikes occurred nationwide last year, up from 1.2 million the year before, or more than 100,000 strikes a month on average.

About 100 people are hit by lightning each year, and 30 of them die.

In one lightning strike at Suvarnabhumi airport recently, several ground staff were injured while loading luggage on to a plane.

Most lightning strikes occur in the South, followed by the Northeast and eastern provinces, particularly Chanthaburi and Trat, Egat said.

Prawit Leesatapornwongsa, director of the Telecommunications Customer Protection Institute, said people should avoid trees, and stay low when lightning strikes, especially if in an open field.

Boonrat Apicharttrison, a 56-year-old journalist, survived a lightning strike during a trip to Cambodia three years ago.

“It came so fast,” Boonrat said. “I didn’t know what happened to me. I spent one day in a Cambodian hospital and another two months in Chulalongkorn Hospital.”

She was left with burns around her neck, but fortunately no brain injury. She believed the lightning was drawn to her by a metal necklace she was wearing.

But Komson Petcharaks, from the High-Voltage Research Laboratory at Chulalongkorn University, said contrary to popular belief, wearing metal or even talking on a mobile phone during a storm would not attract lightning strikes. The lower part of a cloud has negative ions, which try to connect with positive ions on the ground.

“People can be injured from strikes themselves, or strikes which hit the ground then run from the ground to people,” Mr Komson said.

Most people were injured not from lightning strikes directly, but from objects close to them which conduct electricity.

Risk areas include open fields (45%), trees (23%) and water sources (13%).

Lightning also causes problems for power transmission grids, which can affect energy security.

“About 32% of power transmission line errors are caused by lightning,” said Kitti Petchsanthad, Egat’s transmission line technology unit chief.

Egat has 11 lightning detection systems nationwide to help protect the grid, though sometimes they are not enough.
