A total of 112 broadband stations were deployed as three separate subarrays in two separate mobilizations. Each subarray recorded local, regional, and teleseismic earthquakes for a 21‐month period. Although the primary purpose of the array is to characterize the lithosphere and sublithospheric mantle, the array recorded a number of events of potential interest to the broader geoscience community including the Chelyabinsk meteor explosion, North Korean nuclear tests, the deep Mw 8.3 Sea of Okhotsk earthquake, and large megathrust events offshore Chile and in Nepal. The array includes the first dense deployment of seismometers across the Hangay dome, a region previously believed to be relatively aseismic serving as a rigid block focusing strain to the west and south along the Mongolian and Gobi‐Altai. Initial results from local earthquakes recorded by the array suggest that the Hangay is deforming rather than behaving as a rigid block and that the earthquake potential of faults within the Hangay should be incorporated in hazard analysis for Mongolia.
