Ulwahlulo lwezoxakeka

Ukwahlulelwa kwexesha eliphuthumayo lwenziwa ngesiseko sezibonakaliso ezininzi (inani labantu abalimeleyo, umonakalo ongokwenyama, imida yommandla ochaphazelekayo) kwaye ibonakala ngale ndlela:

• Utshintsho. Le meko yenzeke ngaphandle kweyiphi na imeko kwaye ichaphazele ummandla wayo. Naziphi na izenzo ezenzelwe ukucinywa kweemeko ezinobungozi zinokuphela kuphela kwimvume kaRhulumente kwaye akufanele iphikisana nemimiselo esemthethweni yomhlaba kunye nezivumelwano ezikhoyo.

• Federal. Iimeko eziqhelekileyo apho abantu abangaphezu kwama-500 balimala okanye ngaphezulu kweeyunithi ezizigidi ezizi-5 zonakaliswe ngelixesha lesiganeko. Ukuhlanjululwa kuqhutywe ngumbuso olawulayo karhulumente.

• kwiNgingqi. Le meko engxamisekileyo apho inani lamaxhoba lihluka ukusuka kuma-50 ukuya ku-500, umonakalo obuncinci ubuninzi beeyunithi zezigidi ezi-0.5 ngexesha leengozi. Ukuhlanjululwa kuqhutywe ngumbutho olawulayo wendawo.

• Indawo. Kule meko, inani labaxhoba-ubuncinane abantu abangama-50 okanye umonakalo wepropati aludluli kwiiyunithi zezigidi ezi-0.5 ngelixesha lesiganeko. Ukuhlanjululwa kuqhutyelwa phantsi kolawulo lwamandla olawulo lwendawo.

• kwiNgingqi. Iimeko eziqhelekileyo apho abantu abangama-10 okanye abambalwa balimala, okanye iimeko zokuhlala zabantu abangaphezu kwe-100 zaphulwa, okanye umonakalo owenziweyo ungadlulanga ii-unit units ezingama-5 ngexesha leganeko. Ukuhlanjululwa kuqhutyelwa ngamanyango karhulumente ohlala phantsi.

• kwiNgingqi. Kwiimeko ezixakekayo apho abantu aba-10 okanye abambalwa abahluphekileyo, okanye umonakalo wezinto ezibonakalayo ziphantsi kweeyunithi ezili-1 zeeyunithi ngexesha leengozi. Iimeko ezixakeka kuzo zihlala kwintsimi yento ebalulekileyo yoluntu okanye yezoshishino.

Olu hlobo lwezongxamiseko luyamkeleka kwaye lufumaneka kwiindawo ezininzi. Ngokuxhomekeka kwesizathu, banokuba ngabachwephesha kunye nezendalo. Kule xho mekeke kakhulu kwinani lamaxhoba, isixa semonakalo, umgangatho wokungcola kokusingqongileyo njalonjalo.

Ukwahlulelwa kweemeko zongxamiseko zesimo se- anthropogenic:

1. Izingozi zezothutho.

2. Ukuqhuma kunye nemililo.

3. Izingozi apho kukho ingozi yokukhutshwa kwezinto ezinokutsha.

4. Ukuwa kwehlelwe kwezakhiwo.

5. Iziganeko kwiinkqubo zombane.

6. Izingozi ezibandakanya iinkqubo zokuxhasa ubomi kwintlalo.

Njengomthetho, kulo mzekelo, abantu ngokwabo banetyala kwizinga elikhulu okanye eliphantsi. Kwiimeko ezininzi, baba ngamaxhoba ngokwabo. Ngelo xesha, oku akunakutsholwa ngokukhawuleza kokusingqongileyo. Apha, izinto zendalo kunye ne-anthropogenic nezendalo zidlala indima ebalulekileyo. Ngenxa yoko, kunokubakho ingozi kwimpilo okanye kubomi babantu, ukutshatyalaliswa okanye ukutshabalaliswa kwezinto eziphathekayo ezinokwenzeka.

Zonke iintlekele zemvelo zivela phantsi kwefuthe lemikhosi yemvelo, iinkqubo ezenzeka emhlabeni. Ziye zifundwe kakhulu, kodwa ezininzi azikwazi ukuqikelela.

Ulwahlulo lweengxamiseko zendalo:

1. I-Geological: izityikima, ukukhuphuka komhlaba, ukuqhuma kwe-volcanic, ukuwa, izilwanyana, i-avalanche, ukukhukhula komhlaba.

2. Imvula yezulu: i-squalls, iindubhu, iindwangu, isichotho, imvula, ikhephu, iqabunga elikhulu, isomlo, iziphepho, izivunguvungu.

3. Ingqungquthela: i-tsunami, uxinzelelo lweqhwa, ukukhwabanisa kweenqanawa, amaqhwithi e-tropical, izikhukhula, ukuhlukana kweqhwa lonxweme, izikhukhula, imvula yamanzi.

4. Umlilo nemvelo.

5. Izifo zendalo enkulu.

Ukwahlulelwa kwexesha likaxakeka lunokubanzi. Kuxhomekeka kwizinto ezininzi. Nangona kunjalo, naziphi na iziganeko ezinobungozi kubantu kwaye, ukuba kunokwenzeka, kufuneka ziphephe.
