Ngisho noma umbuso uhlukaniswa ngokuthi unengozi ephansi kakhulu yokuzamazama komhlaba, uMichigan uthola ukuzamazama komhlaba. Empeleni, ukuzamazama komhlaba eziningana kuye kwavezwa eDetroit naseMichigan, ikakhulukazi emkhawulweni wezwe ngasemngceleni oseningizimu yePeninsula Ephansi.
Ukuzamazama Komhlaba Okuqhamukayo eMichigan
Ngenkathi ukuzamazama komhlaba okuningi ukuzamazama ukuvama umhlaba ngokuvamile kuvela emaphutha ngaphandle kwawo, kuye kwaba khona ukuzamazama komhlaba okunabantu abathintekayo ngaphakathi eMichigan.
Enye yeqine kunazo zonke yabhalwa ngo-1905 eNhlonhlweni yaseKeeneenaw e-Peninsula Ephezulu, lapho yayizizwa njenge-VII.
Ukuzamazama komhlaba okukhulu kunazo zonke embusweni, okungenani ngokusho kwe-US Geological Survey, kwavela eNingizimu-Central Michigan ngo-1947, lapho kwakubonakala sengathi unamandla VI futhi kwadala umonakalo endaweni ethile eningizimu-mpumalanga yeKalamazoo. Ukuzamazama komhlaba kwakuzwakala kude naseCleveland, e-Ohio; Cadillac, Michigan, Chicago, Illinois; naseMuncie, e-Indiana.
Okunye ukuzamazama komhlaba okunomthelela omkhulu eMichigan kuhlanganisa:
- 1872: Wenona
- 1877: iRedford neGreenfield Village
- 1883: Kalamazoo (uzizwa njengamandla VI)
- 1905: I-Menominee (izwa njengamandla V)
- 1906 & 1909: I-Lake Superior
Ukuzamazama komhlaba okungekho emthethweni ukuxosha umbuso
Imvelo eqinile yombane ogijima kuwo wonke amaMidwest uvumela amagagasi ashukumisayo ukuba ahambe ezindaweni ezikude nakude, kaningi phezu kwemigqa yombuso. Okukhudlwana ubukhulu, ukuzamazama komhlaba okungaze kube khona kungase kuvezwe.
Lokhu kusho ukuthi ukuzamazama komhlaba akudingeki kwenzeke eMichigan ngoba kungabangela ukuzamazama komhlaba lapha.
Isibonelo, amaphutha ngaphakathi kweNew Madrid Seismic Zone ayebhekene nochungechunge lokuzamazama komhlaba ngo-1811 no-1812 owakwazi ukuzamazama komhlaba eMichigan. Eqinisweni, ukuzamazama komhlaba eStroit kusukela ekuzamazama komhlaba kwazizwa njenge-V kwi-Mercalli Earthquake Intensity Scale, isilinganiso se-Seismic.
Okunye Ukuzamazama Komzwe Kwavela eMichigan
- 1870: Ukuzamazama komhlaba kwavela eStart Lawrence Valley phakathi kweMontreal neQuebec eCanada.
- 1886: Ukuzamazama komhlaba kwavela eCharleston, eNingizimu Carolina, lapho kubhaliswe khona ubukhulu be-7.3 futhi kwazizwa njengo-X. In Detroit, yayizizwa njenge-II-III, kanti e Chicago kwakuzwakala njenge-V.

- 1935: Ukuzamazama komhlaba okubhalisa u-6.1 ngesilinganiso esikhulu kakhulu kuvela eTimiskaming Quebec. Ukuzamazama komhlaba kuvezwe eMt. UClemens noPort Huron njenge-V.
- Ngo-1937: Ukuzamazama komhlaba okubhalisa u-5.4 ngesilinganiso esikhulu kakhulu kwavela entshonalanga ye-Ohio, lapho kwakunomuzwa wokuthi ubukhulu be-VIII.
- 1944: Ukuzamazama komhlaba kwavela eSifundazweni SaseSt. Laurence eMasena, eNew York futhi kwazizwa eDetroit.
- Ngo-1968: Ukuzamazama komhlaba okubhalisa u-5.4 esikalini esikhulu kakhulu kwavela eNingizimu-Central Illinois, lapho kwakubonakala khona njenge-VII. Kwakuzwakala emazweni angu-23, kufaka hlangana ukuqina kwami ukuya ku-III eDetroit naseMichigan.
- 1975: Ukuzamazama komhlaba okubhalisa u-6.2 ngesilinganiso esikhulu kakhulu kwavela empumalanga ye-Idaho, lapho kwakunomuzwa wokuthi ubukhulu be-VIII.
- 1980: Ukuzamazama komhlaba okubhalisa ama-5.2 emkhakheni wezinga eliphezulu kuvela enyakatho-mpumalanga yeKentucky, lapho bekuzwakala khona amandla VII. Kwakuzwakala njengesivinini esikhulu II-III eningizimu yeMichigan.
- 1983: Ukuzamazama komhlaba okubhalisa u-5.3 ngesilinganiso esikhulu kakhulu kuvela eBlue Mountain Lake yaseNew York, lapho kwakunomuzwa wokuthi unamandla VI. I-Detroit yayiseqenjini elingaphandle lendawo elithintekile ukuzamazama komhlaba futhi lazibona njengamandla kakhulu II-III.
- 1987: Ukuzamazama komhlaba okubhalisa u-5.1 ngesilinganiso esikhulu kakhulu kuvela ku-Olney, e-Illinois.
- 1998: Ukuzamazama komhlaba okubhalisa u-5.2 ngesilinganiso esikhulu kakhulu kwavela ePennsylvania, empumalanga yeCleveland.
- 2000: Ukuzamazama komhlaba okubhalisa u-5.2 ngesilinganiso esikhulu kakhulu kuvela eKipawa, eQuebec.
- Ngo-2008: Ukuzamazama komhlaba okubhalisa u-5.4 ngesilinganiso esikhulu kakhulu kwavela eningizimu-mpumalanga ye-Illinois ngo-Ephreli 18. Kwakuzwakala njengamandla amakhulu II-IV ezindaweni ezahlukene naseDetroit.
Umsebenzi wakamuva
Ukuzamazama komhlaba kokugcina eMichigan kwenzeka ngoSepthemba 2, 1994 ngaphandle kweLansing kanye ne-3.5 ebhalisiwe ngesilinganiso esikhulu.
Ukuzamazama komhlaba okuphawulekayo okuzokwenzeka eduze neMichigan ngo-2011 kwavela e-Arkansas (ubukhulu be-4.7) ngoFebruwari 28, 2011 noVirginia (ubukhulu 5.8) ngo-Agasti 23. Ukuzamazama komhlaba kweVirginia kwavezwa ngezigaba ezehlukene ezungeze iDroit njenge-Intensity II-III.
