Powerful earthquakes sent multi-story buildings crumbling to the ground in parts of Turkey and Syria, killing thousands of people as rescue operations continue.
Two major fault lines along the Anatolian Plate have generated a number of big quakes. The initial magnitude 7.8 tremor on Monday morning, which was followed by a magnitude 7.6 quake hours later, had the same magnitude as one that killed about 30,000 people in 1939 in northeastern Turkey.
