FDSN Network Information

FDSN code XR (2018-2021) Operated by University of Missouri (MU) (Mizzou)
Network name Tripartite-BIMA (Bangladesh-India-Myanmar Array) (Tripartite-BIMA) Deployment region United States of America
Start year 2018 End year 2021
Short description

The seismology component of this experiment will consist of a 2.5 dimensional transect that will cross from Bangladesh into Myanmar. We will install as many stations as possible on hard rock sites to minimize noise, although this will not be possible in low-lying deltaic areas. The array will consist of three lines. The middle line will be closely spaced in order to image shallow crustal features. It will have a station spacing of 5-10 km in Bangladesh expanding to 15 km in eastern Myanmar. To image the detachment megathrust at 10-20 km depth in the accretionary prism, a 100-km-long section spanning the Bangladesh and India border will have station spacing of 5 km or less. Two flanking lines located ~40 km on either side will have ~40 km spacing. This 80 km wide swath is critical for earthquake locations and body- and surface-wave tomography. The stations will operate for ~2 years, providing ample recordings from a wide backazimuth distribution of local, regional, and teleseismic events, and ambient noise for analysis
