How to Use This Site

Find earthquake and seismic-hazards information by browsing the Publications and EQ Hazard Information links above, or by searching for keywords in the Search box to the right. Additional USSC information may be found on our Facebook and Twitter pages.

Publications are separated into major sections, including Meetings (1994-present), Photographs, Publications, and Slide Sets. Each section contains collections of related items, such as Agendas, Minutes, etc. Click on a collection name to view all of the items in that collection.

Searching will include full-text search of PDF documents, along with any metadata describing each item. You can limit searching to a particular item type, such a document, photograph, or video by unchecking the boxes as needed under All Resources. For more advanced search capability, use the Geographic (Map) Search (spatial search available for items where a location is known) and/or Advanced Search (individual metadata selections) links in the Search box.

Search results will be shown as thumbnails showing the first page of a document, or a photograph, along with the title and author of the item. Click on the item picture to view the item details and to download the item. You can change the results view by selecting the Result Settings button and changing the display option using the Large Preview or List View icons.
