Deep M4.0 Quake Reported in Tajikistan, Following Earlier Shallow Tremor

The event followed a shallower M4.8 jolt days earlier, highlighting how depth drives surface shaking risk.

Overview

  • The National Center for Seismology reported a magnitude 4.0 earthquake in Tajikistan on February 5 at 02:06 IST, locating it at roughly 37.35°N, 71.98°E and a depth of about 135 km.
  • An earlier magnitude 4.8 quake struck the same region on February 1 at a shallow depth of 10 km, which typically produces stronger shaking at the surface.
  • No major damage or casualties were reported in the coverage for either the February 1 or February 5 events.
  • Tajikistan’s mountainous terrain and glacier‑dependent river basins leave communities vulnerable to earthquakes, landslides and floods, with the World Bank projecting about 30% glacier loss by 2050.
  • Assessments from the GFDRR and World Bank recommend designing and rehabilitating infrastructure using scientific hazard information and climate scenarios alongside local knowledge to reduce long‑term risk.
