Just a decade ago, in Akita prefecture, Japan, folks had complained about stress, complications, and other mysterious symptoms. Scientists found that the cause was infrasound coming from a dam constructed several miles away.
The infrasound network is expected to be able to detect atmospheric explosions within the 1 kt range worldwide, with regional and seasonal atmospheric situations figuring out. Air is a really inefficient medium for transferring low frequency vibration from a transducer to the human body.
Scientists by chance discovered that the spinning core or vortex of atornadocreates infrasonic waves. When the vortices are massive, the frequencies are decrease; smaller vortices have larger, though nonetheless infrasonic, frequencies. These low frequency sound waves could be detected for up to 160 kilometres (a hundred mi) away and may help provide early warning of tornadoes. Monitoring Network will encompass 60 stations, each geared up with an array of four microbaragraphs—three positioned on … Read MoreRead More »
