ABSTRACT

Eastern Indonesia is one of the least well‐understood geological domains on Earth, yet the region is one of the few places which is currently undergoing arc‐continent collision. The Banda arc seismic experiment was designed to unravel some of the complex dynamics of convergent tectonics. This passive source experiment is composed of 30 broadband instruments that extend across the Nusa Tenggara Timur region of Indonesia and across Timor‐Leste. This along‐strike deployment allows for seismic imaging and assessment of the spatiotemporal evolution of the collision of oceanic to continental lithosphere of the Indo‐Australian plate with the active volcanic arc. The experiment has been continuously recording broadband seismic data since early 2014 and will continue through the end of 2016, and the data will be archived at the Incorporated Research Institutions for Seismology Data Management Center under network code YS and will be available at the end of 2018.
