Will Green­land Soon Have Vol­ca­noes?

Science Illustrated - - ASK US -

Green­land has a cold and thick con­ti­nen­tal crust, which is sev­eral bil­lion years old. Even if the ice dis­ap­pears, and the pres­sure on the crust dis­ap­pears, the risk of vol­canic ac­tiv­ity in Green­land in min­i­mal. But this phe­nom­e­non is well-known and has had great con­se­quences fur­ther to the east.

Un­til 16,000 years ago, Ice­land was cov­ered by a 1-km-thick layer of ice, which melted over a pe­riod of 4,000 years. The pres­sure re­duc­tion from the lack of ice made the vol­ca­noes on the is­land run wild, and the num­ber of erup­tions grew to 30-50 times of the nor­mal amount. The last ac­tive vol­ca­noes were found in Green­land 55 m years ago.

Melt­ing ice caused Ice­land's vol­ca­noes to wake up. This will not hap­pen in Green­land.
