Secretary Gilberto C. Teodoro Jr., chair of the NDRRMC, directed that communication between central and regional offices be established within 30 minutes of impact. He emphasized that all agencies must stay alert, follow the “Duck, Cover, and Hold” protocol, and prepare for possible evacuation. He also reminded agencies to check the functionality of alarm systems and ensure policies on alarm system redundancy are in place and properly enforced. RDRRMCs and LDRRMCs are responsible for maintaining alarm system readiness and ensuring the timely dissemination of disaster information.
The situation remains under close watch. Authorities continue to urge the public to stay calm and follow official safety guidelines.
