Week of August 22 – 28, 2026
Focus: Earthquake Activity & Public Preparedness
Issue #010
Executive Summary
This week’s earthquake and disaster-preparedness developments centered on a practical challenge: turning hazard information into decisions that schools, local governments, and communities can actually use before and during emergencies.
The Department of Education moved in that direction with the nationwide launch of Project LIGTAS+, an AI-assisted disaster-risk information platform designed to provide schools and local authorities with school-level geohazard information, multi-hazard monitoring, forecasts, automated situation reports, and live incident tracking. Following an earlier pilot, the nationwide rollout represents a broader effort to make hazard information more accessible for operational decisions involving earthquakes, flooding, tropical cyclones, volcanic activity, tsunamis, and other hazards. Recommended actions generated through the system still require field validation and local judgment.
In Baguio City, the local disaster-risk reduction office is urging schools to move away from generic preparedness plans and instead build DRRM arrangements around the hazards they actually face. Schools are being encouraged to identify their priority hazards, map evacuation routes and safe areas, organize school DRRM teams, coordinate with barangays, conduct tabletop exercises and full simulations, and strengthen first-aid and basic life-support capability. The city is also pursuing a proposed ordinance intended to strengthen DRRM requirements for private schools.
The Office of Civil Defense reinforced the same principle from a community perspective: scientific monitoring and hazard information are only useful when they are translated into timely, understandable actions at the local level. LGUs, barangay leaders, disaster officers, and local communicators play a critical role in bridging technical information and the decisions residents must make during emergencies.

A new reinforcing-steel standard has already been approved, but full implementation has not yet arrived. For families building homes during the transition, the issue is not just regulatory—it can determine which minimum steel standard becomes permanently embedded inside their house.
Top Developments
DepEd Takes Project LIGTAS+ Nationwide for School-Level Hazard Intelligence
Source: PNA/DepEd Philippines
The Department of Education has launched Project LIGTAS+ nationwide, expanding an AI-assisted disaster-risk information platform that was previously piloted earlier this year. The system is designed to help schools and local authorities make faster, more localized preparedness and response decisions by combining school-level geohazard information, multi-hazard monitoring, forecasts, automated situation reports, live incident tracking, and exposure data.
Project LIGTAS+ supports monitoring and decision-making for hazards including earthquakes, flooding, tropical cyclones, volcanic eruptions, and tsunamis. Rather than relying only on broad regional warnings, the platform is intended to give education officials and local decision-makers more specific information about schools that may be exposed to particular hazards.
The platform does not replace field assessment or local authority. Recommended actions generated through the system still require validation on the ground and appropriate local judgment, an important safeguard when automated tools are used in disaster operations.
Preparedness Implications:
The nationwide rollout represents a shift toward more localized and anticipatory disaster decision-making in the education sector. If consistently maintained and used alongside verified field information, school-level hazard intelligence could help officials identify exposed facilities earlier, prioritize preparedness measures, and make more informed decisions on class suspensions, evacuations, and emergency response. Its effectiveness, however, will depend on data quality, connectivity, staff training, and how well digital recommendations are integrated with actual conditions on the ground.

Baguio Pushes Schools to Build DRRM Plans Around Their Actual Hazards
Baguio City’s Disaster Risk Reduction and Management Office is urging schools to move away from generic preparedness plans and instead design their DRRM arrangements around the specific hazards present in their own locations.
Schools are being encouraged to identify their two priority hazards, map safe areas and evacuation routes, establish school DRRM teams, coordinate with barangays, and regularly test their plans through tabletop exercises and full simulations. The city is also emphasizing first-aid and basic life-support capability as part of school-level readiness.
The approach is intended to make preparedness more operational: not simply having a written plan, but ensuring that staff, students, parents, and local responders understand what actions to take, where to go, and how to coordinate when a hazard occurs.
Baguio is also pursuing a proposed local ordinance to strengthen DRRM requirements for private schools. The measure remains a proposal and should not yet be treated as approved or in force.
Preparedness Implications:
The value of the initiative lies in matching preparedness measures to actual local risk. Hazard-specific planning, mapped evacuation routes, trained school teams, and regular exercises can make emergency procedures more realistic and easier to execute. The proposed ordinance could also create a more consistent preparedness framework for private schools if it is eventually approved and implemented.

DTI moved toward implementation of PNS 49:2026 in July 2026, but the proposed timetable quickly became the next point of dispute. Part 3 reconstructs the consultation, the April 2027 compliance date, and PISI’s objection to the transition.

Community Preparedness
• Baguio City
In Baguio City, schools are being encouraged to build preparedness plans around the hazards that actually affect their locations. The city’s DRRM office is asking schools to identify their two priority hazards, map safe areas and evacuation routes, establish school DRRM teams, coordinate with barangays, and test their plans through tabletop exercises and full simulations. First-aid and basic life-support capability are also being emphasized as part of school-level readiness.
The approach is intended to move preparedness beyond written compliance. Students, teachers, parents, and school personnel should know where to go, what procedures to follow, and how to coordinate with local authorities when an emergency occurs.

• Tacloban City
In a separate Philippine Information Agency report, an Office of Civil Defense official emphasized that scientific hazard information must be translated into practical actions that communities can understand and carry out.
The message focused on the role of local governments, DRRM officers, barangay leaders, and communicators in bridging the gap between technical hazard information and community-level decisions. Effective preparedness depends not only on collecting and monitoring hazard data, but also on ensuring that warnings and risk information lead to timely, understandable action.
