Colombia advances unified earthquake alerts

Senator María Lucía Villalba of the New Liberalism party has introduced a bill in Colombia's Congress to create a National Early Earthquake Alert System that would unify warnings across mobile phones, radio and television. The proposal seeks to ensure alerts reach every cellphone, regardless of brand, operating system, balance, data access or network congestion.

What does the bill require?

The text sets a six-month deadline for the national government to reach an agreement with phone, radio and television companies on a unified framework for connectivity, interoperability and cybersecurity. That wording creates operational obligations for telecom operators in communications security and technology risk management, according to the materials released on the initiative.

How would the alert work?

According to the Senate's official note, when the public sensor network of the Colombian Geological Service detects an earthquake above a hazard threshold, it would issue a universal, free alert guaranteed to reach all types of phones and operators. The bill explicitly links the Geological Service's scientific infrastructure with the telecommunications layer.

The Senate press release also says radio and television would be automatically interrupted when an earthquake alert is issued. Programming would stop for a few seconds to broadcast an official tone with protection instructions, which would require technical mechanisms for forced interruption and the distribution of a standardized signal for license holders.

Where does the initiative stand?

The filing does not mean Colombia already has a National Early Earthquake Alert System. Pulzo said the bill still has to go through the full legislative process and that any eventual rollout would still require technical, institutional and funding decisions.

Pulzo added that the proposed system would use the few seconds between an earthquake's detection and the arrival of the strongest shaking to warn areas that have not yet received the intense waves. That places it within the typical architecture of early warning systems based on sensor networks.
