Crustal thickness and velocity structure beneath Singapore's seismic network

► We analyse 697 teleseismic receiver functions recorded at Singapore. ► We estimate crustal thickness beneath Singapore via an H − k stacking technique. ► Crustal thickness beneath Singapore ranges between 24 km and 32 km. ► We derive 1D profiles by jointly inverting receiver functions and group velocities. ► 1D velocity models differ significantly from the CRUST2.0 global model.
