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, with authors, journal staff, the editorial board, and reviewers all participating.

《地震譜》是地震工程研究所（EERI）的專業(yè)刊物，每季度出版一次，刊登在2月、5月、8月和11月的印刷版和在線版上。印刷版作為會(huì)員優(yōu)惠的一部分發(fā)送給EERI會(huì)員。在線版免費(fèi)提供給注冊在線訪問的EERI會(huì)員。EERI建立了地震譜，旨在改進(jìn)地震災(zāi)害緩解、準(zhǔn)備和恢復(fù)的實(shí)踐。它旨在滿足從事減少地震損失的各種專業(yè)人員的信息需求：土木、巖土、機(jī)械和結(jié)構(gòu)工程師；地質(zhì)學(xué)家、地震學(xué)家和其他地球科學(xué)家；建筑師和城市規(guī)劃師；公職人員；社會(huì)科學(xué)家；以及所有這些學(xué)科的研究人員。光譜是地震工程實(shí)踐、地震法規(guī)、地震公共政策和地震調(diào)查報(bào)告發(fā)展的記錄發(fā)布。在地震譜中發(fā)表的手稿被同行評審。稿件的提交和同行評審過程是電子化的，作者、期刊工作人員、編輯委員會(huì)和評審員都參與其中。
