How far can seismic waves reach?
Seismic waves are vibrations (i.e. waves of energy) generated by earthquakes. As the vibration propagates, it loses energy and ultimately fades away. The most powerful seismic waves, generated by the most powerful earthquakes, can go around the Earth for several days.
Surface waves generated by a powerful earthquake can travel several times around the world.

Just about anything over M 5.5 will propagate across the entire globe.
Steamboat Geyser is now the world’s largest active geyser. It has erupted ten times in three months, but it wasn’t always so exciting. Before this year– Steamboat erupted ten times in nearly thirty years. According to officials, the activity is spurred on by a large magma field sitting just below the park.
