PASSCAL Experiments http://www.passcal.nmt.edu/rss/experiments en HRIII http://www.passcal.nmt.edu/scheduledetails/exptnumb/201213 An multi-technology experiment (seismic, acoustic, etc) to study the seismo-acoustic source function from above- and below-ground explosions. In addition, the study will involve generation mechanisms of shear waves from explosions in limestone and alluvium. For Phase II, we will conduct additional explosion experiments at the White Sands Missile Range. Early Rifting http://www.passcal.nmt.edu/scheduledetails/exptnumb/201107 The passive seismic experiment is part of a NSF Continental Dynamics project trying to understand the early stage of rifting. Approximately fifty PASSCAL broadband stations will be deployed along 3 rift-orthogonal profiles at an interval of about 50 km at locations outside the rifted valleys, and 20-30 km inside the valleys. Each profile consists of 15-17 stations and is about 550 km long.The portable stations will record for a two-year period with a sampling rate of 100 samples per second.Environment:Low MountainAdditional comments:Approximately 15 stations will be in Botswana, 15 in Zambia, 10 in Congo, 5 in Malawi, and 5 in Tanzania. Given the large area covered by the stations and the logistic complexity, two field teams will be formed: one for Botswana+Congo, and one for Zambia+Malawi+Tanzania. Carbon Sequestration http://www.passcal.nmt.edu/scheduledetails/exptnumb/201108 Seismic data recorded by broadband stations will be used for velocity and attenuation tomography inversions to to track the spatial and temporal variations in Vp/Vs ratios that maybe caused by pumping of CO2 or loss of fluid due to leakage. MNMRS http://www.passcal.nmt.edu/scheduledetails/exptnumb/201211 The aims of the collaborative experiment are to decipher the role of magmatism and volatile release in the initiation of rifting in thick, cold cratonic lithosphere, the pathways for magma and volatile movement through the plates, their influence on the continental lithospheric rheology, and the initiation and maintenance of along-segmentation.
