This dataset was compiled as part of the Data Preservation Program of the Washington Geological Survey, the aim of which is to organize and preserve geologic data in a digital format and to make it easier for the public to obtain. The creation of this trench dataset was prompted by the need for up-to-date and spatially accurate reporting of paleo-seismic investigations of known or suspected faults of Quaternary age in WA State. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Geologists excavate trenches across faults to determine more detailed information about earthquake history on the fault. Information from this type of study includes the direction of fault movement, the number and timing of earthquakes, and the recurrence interval. Finding faults and knowing how often they rupture is one of the most important tasks needed to fully characterize earthquake hazards. Such information moves society towards a full enough understanding of the frequency of earthquakes in a given region to make earthquake forecasting possible.</SPAN></P></DIV></DIV></DIV> |
