Why did so many reinforced buildings with rebar in Turkey fail in Monday’s 7.7 earthquake?
In: 9
The earthquake scale is logarithmic. That means M6 is 10 times stronger than M5 and 100 times stronger than M4. Turkey actually had 4 earthquakes in short time, two nearing 7 and two nearing 8.
Only the most reinforced buildings can survive a magnitude 8 earthquake. So the answer is that the earthquake was simply too strong.
