Permissions Policy

The Seismological Society of America (SSA) no longer requires that permission be obtained from SSA or the author(s) to reprint tables, figures, or short extracts of papers published in SSA journals, provided that the source be appropriately and accurately cited. However, the author's permission must be obtained for modifying the material in any way beyond simple redrawing.

SSA does require that the article be published by SSA before any material may be reprinted therefrom. 

For information on posting papers published in SSA journals on a personal or institutional website please see the SSA Open Access Policy page. Posting of papers published in SSA journals on websites not associated with the author of that paper is not permitted.

Credit citation 

SSA recommends that the credit line read "authors, article title, journal title, volume number, page number(s), year, © Seismological Society of America."
