On September 10, 2026, the 4th Infantry (Diamond) Division of the Philippine Army activated its earthquake response protocols during the 3rd Quarter National Simultaneous Earthquake Drill (NSED) held at Camp Evangelista in Cagayan de Oro City. The exercise put the division’s emergency systems, personnel coordination, and humanitarian response capabilities under a structured, real-time evaluation.
Alarm Triggers Immediate ‘Duck, Cover, and Hold’ Response
The drill was set in motion when alarm signals rang out across Camp Evangelista, triggering the standard protective response: “Duck, Cover, and Hold.” All personnel on the installation immediately assumed the prescribed position as the simulation got underway. Embedded within the exercise was a mock casualty scenario intended to gauge how individual units and response teams handle injuries arising from a simulated seismic event.
The 4th Infantry Division, in a statement released after the activity, noted that the drill simultaneously tested essential equipment, communication systems, and mobility assets to ensure they are fully operational and deployable under emergency conditions.
Personnel Moved Methodically to Designated Safety Zone
Once the initial response phase was completed, all camp personnel proceeded in an organized and disciplined manner to the 4ID parade ground, which served as the primary convergence point for accountability checks. The orderly evacuation was a deliberate component of the exercise, designed to mirror how troops would move and consolidate during an actual earthquake event.
According to the division’s official statement, evaluators and inspectors were stationed at key positions across the installation throughout the evacuation phase. Their role was to observe and score participants in real time, with particular attention given to response speed, inter-unit coordination, evacuation discipline, and compliance with established safety protocols.
Drill Extends to HADR Transition Scenarios
The exercise went beyond basic earthquake survival procedures. A significant portion of the 4ID drill was structured to evaluate the division’s capability to shift seamlessly into Humanitarian Assistance and Disaster Response (HADR) operations — situations where a major earthquake results in mass casualties, widespread infrastructure damage, and prolonged community-level needs.
This HADR component reflects the dual mandate that the Philippine Army carries in crisis situations: preserving the operational readiness of its own forces while simultaneously deploying to provide direct support to civilian communities in distress. The 4ID’s participation in the NSED reinforces this combined responsibility, the division said.
After-Action Review Wraps Up the Exercise at the Grandstand
The drill formally concluded at the 4ID Grandstand, where a consolidation session and After Activity Report (AAR) were conducted. During the AAR, evaluators and unit representatives came together to present their field observations, performance assessments, and specific recommendations for improvement, according to the division’s statement.
Both areas of strength and areas requiring corrective action were identified through this process. The AAR is a standard practice in military training methodology, designed to institutionalize lessons learned from exercises so that identified shortcomings can be addressed well before an actual emergency demands a real response.
Two Senior Colonels Led Coordination and Troop Movement
Overall coordination and implementation of the drill fell under the supervision of the Assistant Chief of Staff for Operations (G3), headed by Colonel Sandy R. Majarocon. His office was responsible for ensuring the exercise unfolded in accordance with established plans and that all participating elements were properly aligned throughout the activity.
Meanwhile, Colonel Michael O. Sumapig, commanding officer of the 4th Installation Management Battalion, oversaw troop movement logistics and provided the operational support necessary to keep the exercise safe and properly sequenced from start to finish.
4ID Commander: Readiness Must Never Lapse
4ID Commanding General Major General Marion T. Angcao underscored that earthquake preparedness cannot be treated as a theoretical exercise or a box-checking activity — effective response capability must be actively sustained across every level of the organization at all times.
“Earthquakes can strike anytime without warning; therefore, readiness must be sustained at all times. In an actual disaster, there is no rehearsal and no opportunity to repeat a decision as lives are at stake,” Major General Angcao said. “Every drill is an opportunity to identify gaps, improve our systems, and ensure that we can quickly support our communities when called upon,” he added.
The general’s remarks reflect a broader institutional posture: that drills of this nature are not ceremonial exercises but functional stress tests of the division’s capacity to protect both its own personnel and the civilian communities it is mandated to serve.
By the Numbers
- September 10, 2026 — Date the 3rd Quarter NSED was conducted at Camp Evangelista in Cagayan de Oro City
- 3rd Quarter — The specific NSED cycle in which the 4ID took part
- 2 senior officers — Colonel Sandy R. Majarocon (G3 office) and Colonel Michael O. Sumapig (4th Installation Management Battalion) led coordination and facilitation of the drill
- 2 key venues — The 4ID parade ground served as the evacuation convergence point; the 4ID Grandstand hosted the concluding AAR and consolidation session
Why This Matters
The Philippines occupies a seismically active zone along the Pacific Ring of Fire, placing it among the nations most vulnerable to destructive earthquakes — making structured drills like the NSED essential tools of national disaster risk reduction rather than optional training exercises. The 4th Infantry Division’s conduct of this drill demonstrates the Philippine Army’s institutionalized role in civil disaster response through HADR operations, extending its mandate well beyond conventional defense functions. As Major General Angcao stated, identifying and addressing systemic gaps during controlled exercises is the only opportunity available — because when a real earthquake strikes, there are no second chances and lives hang directly in the balance.
