HAIDA GWAII (NEWS1130) – A seismologist says it could take decades before a hot springs in Haida Gwaii’s national park returns back to normal. There’s word that it isn’t producing hot water anymore because of Saturday’s 7.7 magnitude earthquake.
Michael Bostock says this is common after a major natural disaster like the one we had. “Fracture systems that were once open allowing hot water to make its way to the surface have been sort of shut off, closed off,” adding the Gwaii Hanaas National Park is a very popular tourist attraction.
He explains if we wait a decade or possibly more, conditions in the area should return back to what existed before the earthquake. “It’s reasonable to infer that those fracture systems that enabled water to make its way to the surface will reopen.”
He says we’re a long way from figuring out how to control these types of things. “A very large earthquake is much more powerful than a nuclear explosion in terms of the total energy released.”
