Locked and loading megathrust linked to active subduction beneath the Indo-Burman Ranges

It is unclear whether subduction is still active beneath the Indo-Burman mountain range. Analyses of GPS measurements from this region reveal a locked megathrust fault, implying that subduction is active and could generate a large earthquake.
