Chile Earthquake Triggered Icequakes In Antarctica

Posted by Unknown on from the continent-vs-continent dept.

sciencehabit (1205606) writes In 2010, a powerful magnitude-8.8 earthquake struck off the coast of central Chile, rocking much of the country and producing tremor as far away as Argentina and Peru. But a new study suggests its effects were felt even farther away—in Antarctica. In the wake of the Maule temblor, the scientists found, several seismic stations on the frozen continent registered 'icequakes,' probably due to fracturing of the ice as the planet's crust shook.

  5. An explanation other than global warming? by American+Patent+Guy · · Score: 2

    Imagine that ... there's another explanation to Antarctic ice depletion other than global warming. Oh, and further yet, it's natural. Chilean earthquake causes ice fractures, and fractures cause movement in the ice.

    Perhaps the sky isn't falling?

      Perhaps the sky isn't falling?

      Perhaps the reverse is true, and the already weakened ice was more affected? Perhaps Chile is geographically close to Antarctica?

      When was the last time we had a magnitude 8.8 quake in Chile to compare against?

      I don't think this earthquake says anything against global warming.

      Unless all ice fractures in Antarctica are caused by earthquakes elsewhere, you can't say that no ice fractures in Antarctica were caused by global warming.

      Neither can the global warming nuts say that the ice coming off of Antarctica is conclusively caused by global warming. I don't need to say that "no" ice fractures were caused by global warming.

      This definitely does say something about the theories of global warming: it shows they are not at certain as their propoundents would like us to believe.
