After several strong earthquakes and aftershocks this year, the nationwide disaster alert system is getting an upgrade.
The Ministry of Public Safety and Security on Monday said that the Korea Meteorological Administration will send text message alerts directly to residents when a quake with a magnitude greater than 3.0 strikes.
For quakes stronger than 5.0, the alerts will be sent in under 50 seconds.
The goal is to get the alerts out in under 25 seconds by the first half of 2017.
People using mobile devices that do not support the notification system -- 3G phones and devices made before 2013 -- can download a special free app.
