Just thought I'd leave this here....the international solidarity and response to the earthquakes in Turkey and Syria amidst the Ukraine war, the tensions between the USA and China and the fear-mongering in the media of a possible WWIII has restored my faith in humanity and makes the hope for world peace alive.

Have earthquakes happened there before?Originally posted by Yemen View Post -
The whole region is technically active and Anatolia itself sits on several different plate boundaries. Nice article here explains it:Originally posted by kara View Post

3 earthquakes in one day, godddammmnnnnComment

Shoddy construction work is to be blamed.
Scenes of thousands of buildings reduced to rubble in southern Turkey and northern Syria following Monday's deadly magnitude 7.8 earthquake — and its many aftershocks —come as no surprise to civil engineer Jonathan Stewart.
"We've seen this before," says Stewart, an engineering professor at the University of California, Los Angeles who was part of an infrastructure assessment team dispatched to Turkey after a major quake struck the north of the country in 1999.
At the time, he says, "there was tremendous loss of life from pancaked buildings.
The region is one of the most earthquake-prone in the world, as it lies in an area where three tectonic plates meet. In addition to the 1999 quake that left more than 17,000 people dead, Turkey also experienced a major quake in 2011 that killed hundreds.
Why did so many buildings fall down? Stewart says that for buildings in Turkey that are more than about three stories tall, a usual construction technique is to use reinforced concrete.
"Typically, the columns and the beams are concrete," he says. "And then there's kind of a masonry infill block inside these frames, which falls apart very quickly when the shaking begins."
Abbie Liel, an engineer and professor at the University of Colorado Boulder, says that assessment pretty much matches what she's seen in photos of the destruction in Turkey.
Instead of this type of brittle construction, she says, engineering a building to withstand earthquakes means factoring in an "ability to deform."
"That involves putting a lot of rebar in all the right places," she says.
Kit Miyamoto, an expert in disaster resiliency engineering who is preparing to head to Turkey as part of a team of engineers, says building codes enacted after the 1999 quake near Izmit are good, but a lot of structures predate those codes.
So after 17,000 died due to earthquakes in 1999, the relevant authorities didn't make sure that they condemn all poorly built building from before? Well, thoughts and prayers I guess. As we can see, not all buildings crumbled like pancakes. So they we basically hoping and praying instead of doing the sensible deeds. At least they are gone to heaven to be with Allah, right?
