An international study reveals unique signals were detected eight months before a 7.8 magnitude earthquake struck Turkey in February.
The authors suggests taking readings from less monitored secondary fault lines could build better earthquake early warning systems.
But Massey University's Lauren Vinnell says even if it becomes possible to forecast an earthquake - it's unlikely we can forecast all of them.
She says she's worried people will assume shaking isn't a quake if it hasn't been forecast - when they should drop, cover and hold.
