The activity console.
Every recorded M≥2.5 event within the Bangladesh window — 20.5°–26.7°N, 88.0°–92.7°E — from the USGS catalog, January 2024 to June 2026. Read it like a cockpit: a monitor, never a prediction.

JAN 2024 – JUN 2026Bubble size = felt reports. Amber = inside Bangladesh · grey = neighbouring region. The Nov 2025 Tungi M5.4 was felt by 989 people.
Magnitude distribution
GR-CONSISTENTGutenberg-Richter: log₁₀(N) = a − b·M · this region b ≈ 0.95–1.05, typical for convergent boundaries.
Alert levels & felt reports
USGS PAGERPAGER alerts are post-event impact estimates — not early warnings. Bangladesh has no operational early-warning system as of 2026.
Depth distribution
DOMINANTLY SHALLOWShallow ≤50 km: crustal faults (Madhupur, Dauki, Sylhet) · 50–150 km: subducting Indian plate · deeper: slab beneath the Myanmar arc.
Annual frequency
2024 → 20262026 counts through June only. Clustering like 2025–26 is statistically normal for an active boundary.

Read this before quoting any number. This console visualises historical USGS catalog data and statistical models (Gutenberg-Richter, PSHA). Alerts are USGS PAGER post-event impact estimates — not early warnings. Probabilities are long-term rates — no model can predict when an earthquake will occur. PSHA values are design-code inputs, not forecasts. Data: USGS ComCat API · 20.5°–26.7°N, 88.0°–92.7°E · M≥2.5 · 24 events, Jan 2024–Jun 2026.
