Mystery seismic waves ripple around the world and no felt it or understands why: report

Seismic waves that began off the coast of Africa rippled around the world earlier this month and no one seemed to be the wiser. The waves began on Nov. 11, about miles off the shores of Mayotte, a French island that sits between Africa and the northern tip of Madagascar, according to National Geographic.
