Seismic-hazard maps for Hawaii Seismic-hazard maps for Hawaii
Probabilistic seismic hazard maps were prepared for Hawaii portraying peak horizontal ground acceleration and horizontal spectral response acceleration for 0.2, 0.3, and 1.0 second periods with probabilities of exceedance of 10% in 50 years and 2% in 50 years. This particular data set is for horizontal spectral response acceleration for 1.0 second period with a 10% probability of...
Aeromagnetic and Gravity Maps of the Central Marysvale Volcanic Field, Southwestern Utah Aeromagnetic and Gravity Maps of the Central Marysvale Volcanic Field, Southwestern Utah
Gravity and aeromagnetic features in the Marysvale volcanic field result from the composite effects of many factors, including rock composition, style of magmatic emplacement, type and intensity of rock alteration, and effects of structural evolution. Densities and magnetic properties measured on a suite of rock samples from the Marysvale volcanic field differ in systematic ways...
