Early earthquake warning systems typically use seismometers to detect incoming fast P-waves. When shaking is felt, a signal is sent to the local seismic authority, which rapidly sends out an alert to those in the region who are likely to feel shaking, hopefully before the more damaging S-waves arrive.
