<P> Several studies conducted in South Asia and Africa suggest that the dangers of lightning are not taken sufficiently seriously there . A research team from the University of Colombo found that even in neighborhoods which had experienced deaths from lightning, no precautions were taken against future storms . An expert forum convened in 2007 to address how to raise awareness of lightning and improve lightning protection standards, and expressed concern that many countries had no official standards for the installation of lightning rods . </P> <P> All events associated or suspected of causing damage are called "lightning incidents" due to four important factors . </P> <Ul> <Li> Forensic evidence of a lightning termination, in the best investigated examples, are minuscule (a pit in metal smaller than a pen point) or inconclusive (dark coloration). </Li> <Li> The object struck may explode or subsequent fires destroy all of the little evidence that may have been available immediately after the strike itself . </Li> <Li> The flash channel and discharge itself are not the only causes of injury, ignition or damages, i.e., ground currents or explosions of flammables . </Li> <Li> Human sensory acuity is not as fine as that of the milliseconds duration of a lightning flash, and our ability to observe this event is subject to the brain's inability to comprehend it . Lightning detection systems are coming online, both satellite and land based, however their accuracy is still measured in the hundreds to thousands of feet, rarely allowing them to pinpoint the exact location of the termination . </Li> </Ul> <Li> Forensic evidence of a lightning termination, in the best investigated examples, are minuscule (a pit in metal smaller than a pen point) or inconclusive (dark coloration). </Li>
