Earthquake in Guatemala

The rescue and relief work in San Marcos, Guatemala, a mountainous region bordering Mexico that was hit by a 7.4 scale earthquake claiming the lives of at least 52 people earlier this month, was aided by emergency communications provided by radio amateurs.

International Amateur Radio Union Region 2 Emergency Communication Coordinator, Cesar Pio Santos HR2P said he was very proud of the work done during and after the earthquake on November 8, despite the difficult times.

Cesar HR2P thanked the members of the Club de Radioficionados de Guatemala (CRAG) for their outstanding efforts.

He was responding to a report from Marco Aurelio TG8AMP, who was in charge of the emergency network in the affected area.

About 10,000 houses have been affected by the earthquake with authorities setting up 11 rescue centres for the homeless. It was the worst to hit Guatemala since 1976, when a 7.5 magnitude earthquake caused the deaths of about 23,000 people in one of the worst natural disasters of the time, again helped by the work of amateur radio.
