Earthquake Spectra, the professional journal of the Earthquake Engineering Research Institute (EERI), is published quarterly in both printed and online editions in February, May, August, and November. The printed edition is sent to EERI members as part of their membership benefits. The online edition is available free to EERI members who register for the online access.

EERI established Earthquake Spectra with the purpose of improving the practice of earthquake hazards mitigation, preparedness, and recovery. It is intended to serve the informational needs of the diverse professionals engaged in earthquake loss reduction: civil, geotechnical, mechanical, and structural engineers; geologists, seismologists, and other earth scientists; architects and city planners; public officials; social scientists; and researchers in all these disciplines. Spectra serves as the publication of record for the development of earthquake engineering practice, earthquake codes and regulations, earthquake public policy, and earthquake investigation reports. Manuscripts published in Earthquake Spectra are peer reviewed. The manuscript submission and peer review process is handled electronically by PeerX-Press (http://eqs.peerx-press.org/), with authors, journal staff, the editorial board, and reviewers all participating.

Periodically, EERI publishes special issues of Earthquake Spectra, either as theme issues or as reconnaissance reports on major earthquakes. All back issues can be viewed and searched at the Spectra Online site.
