alaska and yellostone

story.news.yahoo.com.../nm/20040529/sc_nm/science_geysers_dc this is weird a qake in alaska messed with yellostone in 2002.
what do you think would hapen if a big qake hit the senter of yellostone?

Do you mean, if the super-valcano erupted? It would most likely be a global catastrophe eventually. Within about 600 or so miles radius would be instant destruction then the atmosphere would be loaded with ash and dust occluding the sun which would cause a global winter/ice age in a matter of months.
