Aftershocks are smaller earthquakes that occur in the days that follow a large seismic event. They often do a surprising amount of damage since structures in the region are already weakened. Like aftershocks, donations at this level can have a surprising impact.
Body waves travel below the earths surface at high speeds. Although they do not create much damage, body waves always come before the more destructive surface waves. Like body waves, this donation level will help our campaign to build momentum.
The most destructive type of seismic wave, surface waves have high amplitudes and travel near the earth's surface. Like surface waves, this donation level will have the highest impact.
