Understanding Earthquake Measurement and Its Impact

Monday another earthquake struck southeastern Turkey, near the Syrian border. This time, the quake registered as a magnitude 6.3 — an order lower than the initial, devastating 7.8 magnitude earthquake and the magnitude 7.5 aftershock that struck the area two weeks ago on Feb. 6. A magnitude 6.3 is still considered strong, according to the United States Geological Survey (USGS). And as NPR previously reported, some locals were inside buildings trying to recover belongings lost in the initial quake when Monday's aftershock hit.

It made us wonder: What are aftershocks? And how long will people in Turkey and neighboring countries like Syria have to endure aftershocks while piecing their lives back together? Days? Years?

For answers, we turned to earthquake geologist Wendy Bohon, who we've previously spoken to about the limitations of earthquake detection.
