Kuthamanga kukwera pamwamba pa moto wolusa ndiye chifukwa chimodzi chachikulu chakupha anthu wamba komanso ozimitsa moto akutchire. Chifukwa chakuti mpweya wotentha umatuluka ndi kutentha kowala kumatenthetsa zomera za m’mwamba, moto wokwera kutsetsereka kwa madigiri 30 umayenda mofulumira kuŵirikiza 4 mpaka 16 kuposa pamalo athyathyathya, kufika mosavuta pa 15 mpaka 25 km/h (9 mpaka 16 mph) kwinaku ukudutsa mipweya yakupha yotentha kwambiri m’mitsinje ndi zishalo. Mosiyana ndi izi, malo omwe adawotchedwa kale phulusa lakuda ndi dothi lamchere ("wakuda") ali ndi mafuta osayaka osayaka. Kulowa mumdima wakuda kuseri kwa lawi lotsika kwambiri kapena kumbuyo kwamoto kumatsimikizira kuti kutsogolo kwamoto sikungakuyakaninso.

Ngati ndikuyendetsa galimoto m'chigwa chakumidzi kapena mumsewu wamtchire pamene mphezi yowuma imayaka moto wambiri pamsewu, kodi ndisiye galimoto yanga ndi kuthamanga wapansi?¶

Pafupifupi ayi: Galimoto yachitsulo yolimba kwambiri imapereka chitetezo chokwanira cha Faraday-khola ku mphezi komanso chitetezo champhamvu kwambiri ku kutentha ndi utsi wonyezimira poyerekeza ndi kuthamanga poyenda wapansi. Ngati mutha kuyendetsa bwino m'mapiri komanso kutali ndi utsi, pitilizani kuyendetsa nyali zakutsogolo ndi zowunikira ma hazard, mazenera okulungidwa, ndi zoziziritsa kukhosi zakhazikitsidwa kuti zizizunguliranso mkati. Ngati mitengo yakugwa kapena utsi wosawoneka bwino utatsekereza msewu wonse, ikani pamalo otalikirapo opanda kanthu, miyala, kapena pokokera patali kwambiri ndi burashi ya m’mbali mwa msewu ndi mitengo momwe mungathere, zimitsani injini, sungani mazenera mwamphamvu, tsikirani pansi pazipinda zapansi pa mzere wa zenera (pamene galasi limatchinga kutentha kowala), ndipo dziphimbe ndi bulangeti laubweya kapena thonje pamoto woyaka moto mpaka mphindi zitatu itayaka moto.

*Bukhuli ndi lofuna kudziwa zambiri ndipo sililowa m'malo mwa ovomerezeka a bungwe lozimitsa moto ku wildland kapena maphunziro a momwe angapulumuke m'chipululu. Timalimbikitsa kwambiri kutenga maphunziro ovomerezeka a Wilderness First Aid kudzera ku Wilderness Medical Society, Red Cross, kapena St John Ambulance, ndikumaliza maphunziro aulere okonzekera moto wamtchire operekedwa ndi National Wildfire Coordinating Group (NWCG) kapena ntchito yanu yozimitsa moto yakumidzi.

Maupangiri ogwirizana¶

• Moto wamtchire: kuthawa, malo otetezedwa, ndi kupulumuka kotsekeredwa
• Mvula yamkuntho ndi chitetezo cha mphezi
• Zizindikiro zochenjeza za mphezi zomwe zatsala pang'ono kugunda (tsitsi liyimilira kumapeto) ndi mphamvu yapansi
• Microburst, kunyowa motsutsana ndi kuphulika kowuma, kumeta ubweya wamphepo, ndi kuwonongeka kwa mizere yowongoka
• Kuphulika kwamoto, firenadoes, ndi pyrocumulonimbus plume kugwa
• Nambala zadzidzidzi malinga ndi dziko
