Hydrothermal hydrocarbon gases: 1, genesis and geothermometry
Various sources for hydrothermal CH4 have been proposed over the years. While C isotope studies have narrowed the possibilities, enough higher hydrocarbon gas data now exist both to supplement the isotopic data and to ...
Recent vertical deformation in Mexicali Valley and its relationship with tectonics, seismicity, and the exploitation of the Cerro Prieto Geothermal Field, Mexico
The interpretation of the results of regional and local leveling which began in 1977 in the Mexicali Valley and the local short profile precision leveling which started in 1994 are discussed. The relation of vertical ...
Two M-w 4.8 Cerro Prieto, Baja California, Mexico, earthquakes on 1 June and 10 September 1999: Strong-motion observations
We analyzed the strong-motion records of two M, 4.8 normal-fault earthquakes that occurred in June and September 1999 in the sedimentary environment of the Mexicali Valley. Peak ground accelerations of up to 0.452g were ...
Intermediate-term declines in seismicity at Mt. Wrangell and Mt. Veniaminof volcanoes, Alaska, following the 3 November 2002 M-W 7.9 Denali fault earthquake
The M-W 7.9 Denali fault earthquake ruptured segments of the Susitna Glacier, Denali, and Totschunda faults in central Alaska, providing a unique opportunity to look for intermediate-term (weeks to months) responses of ...
