Bangladesh Seismic Intelligence 1726-2050
Explore 300 years of Bangladesh earthquake history and probabilistic future projections to 2050. This dashboard integrates data from the USGS, Bangladesh Meteorological Department (BMD), Geological Survey of Bangladesh (GSB), Global Earthquake Model (GEM) Foundation, and UNDRR seismic risk assessments.

42 Historical Earthquakes

From the 1762 M8.8 Arakan earthquake to the 2026 M5.5 Mymensingh event. Every major earthquake plotted with magnitude, depth, MMI, casualties, and associated fault.

〰️

12 Active Fault Lines

Dauki Fault (M8.5+), Madhupur Fault (M7.5), Indo-Burma Megathrust (M8.8), Sitakunda, Sylhet-Assam, and the newly discovered 400km Jamalpur-Mymensingh-Kolkata fault.

🔮

24 Probabilistic Projections (2027-2050)

Based on PSHA recurrence intervals, fault slip rates, and linear regression models. Conditional probabilities for each projected event.

64 District Risk Profiles

PGA values, seismic zones, building vulnerability, population exposure, and historical damage for every district. Click any district marker.

⚠️ Critical Seismic Insights
Bangladesh sits at the collision of three tectonic plates — Indian, Eurasian, and Burma. The 1762 Arakan M8.8 was the strongest; 1897 Assam killed 1,542+. The Dauki Fault can generate M8+; Madhupur Fault (70km from Dhaka) M7.5. A M7.5 on Madhupur could severely damage 20-25% of Dhaka buildings. PBF2 (Dauki extension) has >6.7% probability of M8 in 50 years. Linear regression predicts M6.1 by 2040, M6.8 by 2050.
