One of the world’s leading seismologists discusses the disaster in Turkey and Syria a month later.
At around 4 a.m. on February 6, the ground in southern Turkey and northern Syria shook for more than a minute, while most people were asleep.
A magnitude 7.8 earthquake – with an epicenter 32km (20 miles) west of the Turkish city of Gaziantep – had hit the region, breaking up the ground and causing extensive damage.
And nearly 10 hours later, another magnitude 7.5 seismic event shook the region again.
Since then, more quakes and aftershocks followed.
But what can we learn from what happened in Turkey and Syria a month ago?
