QUAKELINE® Database Advanced Search

The advanced search features several tools, allowing the user to frame the query in precise terms. Each search string entered in a Search Terms box uses a single field and use no more than two words for each string. Up to four search strings with four distinct fields can be joined using Boolean operators: and, or, not, and adjacent. The last search allows the user to limit the query to a "year" or "range of years". Choose the submit button to process the query or the reset button to clear the search terms.
