These countries manage seismic networks that contribute to the European Integrated Data Archive node in the framework of the Observatories and Research Facilities for European Seismology, which represents a collaborative effort in coordinating observational seismology across the European region through the collection, archiving, and dissemination of seismic waveform data, metadata, and related products. All of the aforementioned countries share a common threat: strong earthquakes occurring in the Vrancea area located in central-eastern Romania at intermediate depths (usually in the 60\u2013180\u00a0km interval). Events such as the ones on 10 November 1940 and 4 March 1977 generated high damage in Romania, northern Bulgaria, and Moldova. In addition to Vrancea, crustal earthquakes in areas such as Shabla or Dulovo can lead to cross-border damage. Therefore, understanding the way national seismic networks are distributed, how they cooperate, and the products and services that they provide in (near) real time and their terms is of significant interest in the context of necessary hazard harmonization and joint emergency intervention and risk mitigation actions.<\/jats:p>","DOI":"10.1785\/0220200393","type":"journal-article","created":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T17:59:13Z","timestamp":1614794353000},"page":"1685-1703","source":"Crossref","is-referenced-by-count":22,"title":["From National to Transnational Seismic Monitoring Products and Services in the Republic of Bulgaria, Republic of Moldova, Romania, and Ukraine"],"prefix":"10.1785","volume":"92","author":[{"given":"Alexandru","family":"M\u0103rmureanu","sequence":"first","affiliation":[{"name":"National Institute for Earth Physics (NIEP), Magurele, Ilfov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Constantin","family":"Ionescu","sequence":"additional","affiliation":[{"name":"National Institute for Earth Physics (NIEP), Magurele, Ilfov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bogdan","family":"Grecu","sequence":"additional","affiliation":[{"name":"National Institute for Earth Physics (NIEP), Magurele, Ilfov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dragos","family":"Toma-Danila","sequence":"additional","affiliation":[{"name":"National Institute for Earth Physics (NIEP), Magurele, Ilfov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandru","family":"Tiganescu","sequence":"additional","affiliation":[{"name":"National Institute for Earth Physics (NIEP), Magurele, Ilfov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristian","family":"Neagoe","sequence":"additional","affiliation":[{"name":"National Institute for Earth Physics (NIEP), Magurele, Ilfov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victorin","family":"Toader","sequence":"additional","affiliation":[{"name":"National Institute for Earth Physics (NIEP), Magurele, Ilfov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iolanda-Gabriela","family":"Craifaleanu","sequence":"additional","affiliation":[{"name":"National Institute for Research and Development in Construction, Urban Planning and Sustainable Spatial Development (URBAN-INCERC), Bucuresti, Romania"},{"name":"Technical University of Civil Engineering Bucharest, Bucuresti, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudiu Sorin","family":"Dragomir","sequence":"additional","affiliation":[{"name":"National Institute for Research and Development in Construction, Urban Planning and Sustainable Spatial Development (URBAN-INCERC), Bucuresti, Romania"},{"name":"Faculty of Land Reclamation and Environmental Engineering, UASVM Bucharest, Bucuresti, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasile","family":"Mei\u0163\u0103","sequence":"additional","affiliation":[{"name":"National Institute for Research and Development in Construction, Urban Planning and Sustainable Spatial Development (URBAN-INCERC), Bucuresti, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oleksandr Ivanovich","family":"Liashchuk","sequence":"additional","affiliation":[{"name":"Main Center of the Special Monitoring, Space Facilities Control and Test Center, State Space Agency of Ukraine, Kyiv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liliya","family":"Dimitrova","sequence":"additional","affiliation":[{"name":"National Institute of Geophysics, Geodesy and Geography, Bulgarian Academy of Sciences (NIGGG \u2013 BAS), Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ion","family":"Ilie\u015f","sequence":"additional","affiliation":[{"name":"Institute of Geology and Seismology (IGS), Chi\u015fin\u0103u, Republic of Moldova"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"790","published-online":{"date-parts":[[2021,3,3]]},"reference":[{"issue":"3","key":"2021042616563767200_rf1","doi-asserted-by":"crossref","first-page":"1025","DOI":"10.1193\/070913EQS198M","article-title":"Summary of the ASK14 ground motion relation for active crustal regions","author":"Abrahamson","year":"2014","journal-title":"Earthq.
