Hurricane Sandy created seismic activity on US West Coast

Hurricane Sandy literally shook the entire United States, according to new research.

Apparently, when the October storm crashed into the US East Coast it shook the seafloor so violently that seismological activity was felt all the way to Seattle.

Researchers at the University of Utah said that crashing waves sent tremors into the seafloor, sending a shockwave through the Earth's crust.

The tremors were similar to a magnitude 2 or 3 earthquake.

Having events show up on seismometers is nothing new.

Hurricane Katrina also registered like an earthquake, as did a Utah coal mine collapse in 2007.
