Magnitude 4.2 Quake Strikes Northern Myanmar

It underscores Myanmar’s ongoing seismic vulnerability at the junction of four tectonic plates along the 1,400-kilometre transform fault.

Myanmar is wedged between four tectonic plates (the Indian, Eurasian, Sunda, and Burma plates) that interact in active geological processes. (Pic used for representation)

Overview

  • The tremor occurred at 02:42:47 IST on August 4 at a depth of 10 km near 20.88 °N, 95.82 °E, according to the National Centre for Seismology.
  • No immediate reports of structural damage or injuries have emerged following the earthquake.
  • Myanmar occupies a complex tectonic setting where the Indian, Eurasian, Sunda and Burma plates converge.
  • A 1,400-kilometre transform fault links the Andaman spreading centre to the Sagaing Fault, amplifying regional seismic hazards.
  • Major population centres along the Sagaing Fault corridor—including Sagaing, Mandalay, Bago and Yangon—remain at elevated risk from earthquakes and potential tsunamis.
