🔴 1️⃣ IMMEDIATE OPERATIONAL RECOMMENDATIONS (Short Term)
================================================================================

🚨 CRITICAL ZONES (CHI ≥ 0.8):
--------------------------------------------------

📍 Miyako, Japan:
   • Activate high coastal alert protocol
   • Close low-lying coastal areas and waterfronts
   • Suspend nearshore navigation
   • Switch monitoring teams to high-frequency mode

📍 Banda Aceh, Indonesia:
   • Activate high coastal alert protocol
   • Close low-lying coastal areas and waterfronts
   • Suspend nearshore navigation
   • Switch monitoring teams to high-frequency mode

✅ No high risk zones detected

================================================================================
🛠️ 2️⃣ TECHNICAL RECOMMENDATIONS (Mid Term)
================================================================================

📈 Add CHI temporal derivative (dCHI/dt):
   • Not as new indicator, but as internal monitoring value
   • Helps distinguish between:
     - Wave heading toward instability
     - Wave peaking and beginning to decay

⏱️ Guaranteed minimum warning window: 15 minutes
   • Extended warnings (20-25 min): Bonus, not guarantee

📋 System limitations:
   • Does not work with: Complex bathymetry
   • Does not work with: Incomplete pressure data

================================================================================
🎯 3️⃣ STRATEGIC RECOMMENDATIONS (Long Term)
================================================================================

🌊 Complete independence from seismic data:
   • System describes physical state, does not predict

📊 CHI is sufficient:
   • No need for new indicators at this stage

📑 Report = Primary product:
   • Algorithm stays behind the curtain
   • Report is what drives decisions

================================================================================
📋 FINAL OPERATIONAL SUMMARY
================================================================================

🔴 CRITICAL ZONES (CHI ≥ 0.8): 2
   • Miyako, Japan: CHI = 0.821
   • Banda Aceh, Indonesia: CHI = 0.823

🟡 HIGH RISK ZONES (0.6 ≤ CHI < 0.8): 0

🟢 MODERATE ZONES (CHI < 0.6): 3

================================================================================
✅ System ready operationally, improvable scientifically
