Eruptive activity at Mount St Helens, Washington, USA, 1984-1988: a gas geochemistry perspective Eruptive activity at Mount St Helens, Washington, USA, 1984-1988: a gas geochemistry perspective
The results from two different types of gas measurement, telemetered in situ monitoring of reducing gases on the dome and airborne measurements of sulfur dioxide emission rates in the plume by correlation spectrometry, suggest that the combination of these two methods is particularly effective in detecting periods of enhanced degassing that intermittently punctuate the normal background...

Seismic hazards at Kilauea and Mauna Loa volcanoes, Hawaii Seismic hazards at Kilauea and Mauna Loa volcanoes, Hawaii
A significant seismic hazard exists in south Hawaii from large tectonic earthquakes that can reach magnitude 8 and intensity XII. This paper quantifies the hazard by estimating the horizontal peak ground acceleration (PGA) in south Hawaii which occurs with a 90% probability of not being exceeded during exposure times from 10 to 250 years. The largest earthquakes occur beneath active...

The importance of earthquake-induced landslides to long-term slope erosion and slope-failure hazards in seismically active regions The importance of earthquake-induced landslides to long-term slope erosion and slope-failure hazards in seismically active regions
This paper describes a general method for determining the amount of earthquake-induced landsliding that occurs in a seismically active region over time; this determination can be used as a quantitative measure of the long-term hazard from seismically triggered landslides as well as a measure of the importance of this process to regional slope-erosion rates and landscape evolution. The...

Historical shoreline mapping (II): Application of the Digital Shoreline Mapping and Analysis Systems (DSMS/DSAS) to shoreline change mapping in Puerto Rico Historical shoreline mapping (II): Application of the Digital Shoreline Mapping and Analysis Systems (DSMS/DSAS) to shoreline change mapping in Puerto Rico
A new, state-of-the-art method for mapping historical shorelines from maps and aerial photographs, the Digital Shoreline Mapping System (DSMS), has been developed. The DSMS is a freely available, public domain software package that meets the cartographic and photogrammetric requirements of precise coastal mapping, and provides a means to quantify and analyze different sources of error in...

Decade-scale trend in sea water salinity revealed through d18O analysis of Montastraea annularis annual growth bands Decade-scale trend in sea water salinity revealed through d18O analysis of Montastraea annularis annual growth bands
Stable oxygen isotope ratios (1)180) of coral skeletons are influenced by ambient water temperature and by the oxygen isotope ratio in the surrounding sea water, which, in turn, is linked to evaporation (salinity) and precipitation. To investigate this relationship more thoroughly, we collected hourly temperature data from the Hen and Chickens Reef in the Florida Keys between 1975 and...

Seismic structure of the uppermost mantle beneath the Kenya rift Seismic structure of the uppermost mantle beneath the Kenya rift
A major goal of the Kenya Rift International Seismic Project (KRISP) 1990 experiment was the determination of deep lithospheric structure. In the refraction/wide-angle reflection part of the KRISP effort, the experiment was designed to obtain arrivals to distances in excess of 400 km. Phases from interfaces within the mantle were recorded from many shotpoints, and by design, the best...
