• true 
• false

• at plate boundaries

How do scientists find the epicenter of an earthquake?

• by comparing arrival times of P waves and S waves at several seismograph stations
• by digging at several locations and comparing data
• by comparing departure times of P waves and S waves at several seismograph stations
• by reviewing satellite photos of tsunamis

What is the epicenter of an earthquake
