Sometimes is the current underground conducted very badly (there may be relatively low humidity), and currents are then spread over the the ground much longer, and cause in crop cereals much more damages. The field can then be flattened (damaged, weakened) up about 90%. (photo)
Minsan gamit ang mga kasalukuyang underground isinasagawa napaka-di-wastong (maaaring may relatibong mababa kahalumigmigan), at alon ay pagkatapos kumalat sa ibabaw ng lupa mas matagal, at sanhi ng mga cereal sa mga pinsala crop higit pa. Field ay maaaring pipi (nasira, Weakened) ang tungkol sa 90%. (photo)
