Earthquake Scenario (Source)

| Mw
Select a scenario earthquake. DSHA evaluates: "IF this earthquake occurs, what is the ground shaking at my site?"

Site Location (Receiver)

Soil Conditions (Vs30)

Vs30 = Average shear wave velocity in top 30m. Higher values = stiffer ground = lower amplification.
Known Vs30 Values (Bangladesh):
• Dhaka: 180-250 m/s (Class D)
• Chittagong: 250-350 m/s (Class C-D)
• Sylhet: 200-280 m/s (Class D)
• Khulna: 150-200 m/s (Class D-E)
• Rajshahi: 220-300 m/s (Class D)
Selecting a district shows coordinates. Set Vs30 manually as needed.

Analysis Tools

DSHA is scenario-based. It answers: "IF this specific earthquake occurs, what is the shaking?" Probability is NOT calculated in DSHA.
