Extended Data Fig. 1: nBOSS and MetMalaysia seismic networks.
From: Post-subduction tectonics induced by extension from a lithospheric drip
The nBOSS seismic experiment includes 46 temporary seismic stations (yellow squares), augmented by 28 permanent stations of the seismic monitoring network operated by the Meteorological Department of Malaysia (MetMalaysia, pink squares). Sensors of the nBOSS network deployed in the field are 3-component Güralp CMG-3ESPCDs (18 in total) and 6TDs (28 in total). MetMalaysia data are detected using Streckeisen STS-2 sensors. When the two seismic networks are jointly used (bottom histograms), they make a dense seismic network with an average station separation of 32 km, capable of resolving relatively fine structure below Sabah (for comparison, the USArray has an average station separation of ~70 km). In this study we use all data available from the nBOSS network, which operated between March 2018 and January 2020. The same time window has been used for data generated by MetMalaysia. MK and CR denote the location of Mt Kinabalu and Crocker Range, respectively. Histograms in the lower panels illustrate the station separation of the nBOSS network with and without inclusion of MetMalaysia stations.
