Seismic Risk Analysis - Pagadian City

⚠️

SENIOR SEISMOLOGIST ADVISORY

Based on paleoseismic studies and Bayesian probability models, the Sindangan-Cotabato Fault System passing through Zamboanga del Sur represents a SIGNIFICANT SEISMIC HAZARD. Historical recurrence intervals suggest major earthquakes (M7.0+) occur every 350-500 years. The last major rupture was approximately 400+ years ago, placing us within the statistical window for potential reactivation.

ACTIVE FAULT LINES

Sindangan-Cotabato Fault
  • Distance from Pagadian: 15-25 km (VERY CLOSE)
  • Type: Strike-slip fault
  • Length: ~200 km
  • Maximum Potential: M7.5-7.8
  • Slip Rate: ~3-5 mm/year
  • Last Major Event: ~1600s (est.)
  • Recurrence: 350-500 years
Zamboanga Fault
  • Distance: 40-60 km
  • Type: Normal fault
  • Maximum Potential: M7.0-7.2
  • Slip Rate: ~2 mm/year
Cotabato Trench (Subduction)
  • Distance: 80-100 km offshore
  • Type: Subduction zone
  • Maximum Potential: M8.0+ (MEGA-THRUST)
  • Tsunami Risk: HIGH for coastal areas

BAYESIAN PROBABILITY ANALYSIS

Using Poisson probability model with Bayesian updating based on elapsed time since last major event:

P(event in next T years) = 1 - e^(-T/μ)
Where μ = mean recurrence interval (425 years)
Elapsed time since last event: ~420 years

Conditional Probability (given elapsed time):
P(M7.0+ in next 50 years | 420 years elapsed) ≈ 28-35%
P(M7.0+ in next 100 years | 420 years elapsed) ≈ 45-55%

⚠️ WORST-CASE SCENARIOS

SCENARIO 1: Sindangan-Cotabato Fault Rupture (M7.5)

EXPECTED INTENSITY

PHIVOLCS VIII-IX (Destructive to Very Destructive)

GROUND SHAKING

45-90 seconds of violent shaking

LIQUEFACTION RISK

HIGH in coastal & low-lying areas

AFFECTED BARANGAYS

ALL 54 barangays (214,000+ people)

Expected Damage: 30-50% of structures damaged/collapsed, landslides in hilly areas (Lison Valley, Napolan), potential dam failures, road network disruption for weeks.

SCENARIO 2: Cotabato Trench Megathrust (M8.2) + Tsunami

TSUNAMI ARRIVAL

15-30 minutes after earthquake

WAVE HEIGHT

3-8 meters at coastline

INUNDATION

500m-1km inland

HIGH-RISK BARANGAYS

Kawit, Balangasan, Santa Maria, Dampalan, White Beach

Historical Reference: 1976 Moro Gulf Earthquake (M7.9) generated tsunami killing 5,000-8,000 people. Pagadian Bay is similarly vulnerable.

✅ REQUIRED PREPAREDNESS SOLUTIONS

🏗️ Infrastructure
  • Retrofit pre-1990 buildings to seismic code
  • Identify and reinforce critical facilities
  • Install seismic isolation in hospitals/schools
  • Bridge and road vulnerability assessment
🚨 Early Warning
  • Deploy local seismometers (P-wave detection)
  • Install tsunami warning sirens in coastal barangays
  • Cell broadcast emergency alerts
  • Community-based early warning system
👥 Community
  • Quarterly earthquake drills (all 54 barangays)
  • Tsunami evacuation route signage
  • Family emergency kits (72-hour supply)
  • Train 54 BQRTs in search & rescue
🏥 Response Capacity
  • Pre-position rescue equipment
  • Mass casualty incident training
  • Identify helicopter landing zones
  • Establish mutual aid agreements

FAULT LINE MAP

Scientific Disclaimer: These projections are based on available paleoseismic data, GPS measurements, and statistical models. Earthquakes cannot be predicted with certainty. However, probabilistic seismic hazard assessment (PSHA) provides valuable guidance for preparedness. Data sources: PHIVOLCS, USGS, peer-reviewed literature. The absence of recent large earthquakes does NOT mean the area is "safe" - it may indicate accumulated strain awaiting release.
