By analyzing data from the 2011 Tohoku earthquake off the coast of Japan, researchers have identified a prompt gravity signal that precedes seismic waves. These gravity signals could be used to circumvent earthquake hazards, such as tsunamis, by forecasting seismic activity earlier than current warning systems.
