Glacial earthquakes have been increasingly documented in recent years. In Greenland, these mysterious quakes have increased seven-fold in the past 20 years. Now, scientists believe they have figured out the dramatic geophysical effect brought by the rumbling phenomenon after large chunks of ice broke off of a glacier and made a huge splash into the cold waters. In a recent study published in the journal Science, researchers explained that glacial earthquakes can cause a seismic event detectable across the Earth.
