The Armenia array is a local seismic network that consists of 13 semi-broadband (Güralp CMG-6TD) stations covering the northern and western part of Armenia with an interspace of 30-50 km. This array was developed for the purpose of collaborative researches on seismology, active tectonics and volcanology in the Caucasus orogeny that were formed by the Eurasia-Arabian collision. Three parties from Armenia and Taiwan deeply involved with the deployment and maintenance of the networks: (1) the Institute of Geological Sciences (IGS), National Academy of Sciences, Armenia; (2) the Institute of Earth Sciences of Academia Sinica, Taiwan; (3) Department of Geosciences, National Taiwan University, Taiwan. The network started its operation with a few stations since late 2012 and then finally reached the current configuration by December of 2014. Among the stations, all instruments are provided by Taiwan research team except for site BYUR (belonging to IGS). The seismic data collected by this array are the contributions of the principal investigators (PIs) of related projects funded by multiple sources in both countries. Details of funding are indicated in the acknowledgement of our paper (Lin et al., 2020). In April 2020, PIs of the project agreed to release the global event data (for earthquakes with M>6.0 between 2012-2017) to the public on TEC Data Center. We hope this unique dataset would benefit to the research community in many ways.
