I live in Turkey and know numerous folks who were in the quake, or had family members in the quake. No one got any sort of alert.
Weird flex, Google.
Edit: To make things clear, I'm not implying that Google had any responsibility to anyone as far as Earthquake reporting is concerned; I simply find it odd they would insist that "no no no the system totally worked' when it clearly didn't. A lot of people died, maybe don't use this specific incident to make your point?
