All mobile phone users in South Korea will automatically receive a text message alerting when an earthquake strikes.
The Korea Meteorological Administration announced on Monday the implementation of the newly created SMS quake alert service.
Messages will be sent when tremors with a magnitude 3.0 to 3.5 are detected on land and between 3.5 and 4.0 magnitude are recorded offshore.
KMA Administrator Kim Jong-seok said the move is aimed at relieving anxiety among the general public, and vowed his agency will do all it can to prevent harm and damage.
