Meet the winners and runners-up of the Statewide Poster Contest, a new initiative to teach students about geothermal energy
Microseismicity
Tiny earthquakes that result from slip or shear along a fracture caused by an uneven distribution of stress. The displacements are very small scale and unfelt at the surface. They can only be detected with sensitive equipment such as geophones and accelerometers, which can be deployed on the surface or in boreholes.
Geothermal Glossary
Word of the Week – Adularia
Adularia Hydrothermal potassium bearing feldspar that forms in volcanic hosted geothermal reservoirs and is a favorable indicator of boiling and permeable conditions.
Word of the Week – Aquifer
Aquifer Porous and permeable rock unit or unconsolidated layer in the subsurface in which all the pores and voids are filled with water. Water supply for wells comes from aquifers.
Word of the Week – Basalt
Basalt Dark grey fine grained volcanic rock composed of plagioclase, pyroxene and olivine, with relatively low silica (45-52 wt %). The composition reflects an upper mantle origin. Basalt is the most common type of volcanic rock on Earth, and it erupts from mid-ocean...
