The Division of Geology and Earth Resources has assembled and maintained a wide range of geoscience data and collections, which provide information to improve state and local government planning and help protect people, infrastructure, and other important resources. Geoscience data and collections (such as, rock and sediment cores, geophysical data, engineering records, historical coal mine maps, and fossils) are used to discover and develop natural resources, such as geothermal energy, to fulfill our energy needs. These data are essential in determining the availability of a earth material, such as sand and gravel for road building and limestone for making cement. Geoscience data and collections are also important to make our state more resilient to earthquakes, tsunamis, landslides, and volcanic eruptions.
We have recently introduced the Washington State Geologic Information Portal as a way to make these data more readily accessible to goverment, the scientific community, industry, and the general public.
