The 900 instrument Mount St. Helens nodal array recorded continuous data for approximately two weeks in the summer of 2014 and was deployed contemporaneously with the active source component of the iMUSH experiment (imaging Magma Under St. Helens). Two distinct imaging methodologies are applied to node data 1) reverse time imaging (RTI) is used to automatically detect and locate microseismicity...
[1] Characterizing the hydration state of the forearc mantle wedge yields valuable information on frictional stability at the downdip edge of subduction megathrusts. Simultaneous inversion of Pand S-wave arrival times collected as part of the Costa Rica Seismogenic Zone Experiment yields 1D and 3D Pand S-wave velocity models (VP and VS) for the Nicoya Peninsula segment of the Middle America Tre...
We have derived an analytical expression in the wavenumber domain for calculating the gravity anomaly caused by an exponential density contrast model for an interface (Xia and Sprowl, 1990), above which the density contrast changes exponentially with depth. Constant density contrast and a linear density contrast are specific cases of the exponential density contrast model. The formula should be...
abstract the current study sets out 1) to investigate the strategic needs of iranian efl learners in reading literary and non-literary texts; 2) to shed some light on the differences between reading literary and non-literary texts; and 3) to specify the differences in the interaction of participants with texts while reading two literary subgenres ( i.e., short story and literary essays). to ...
a r t i c l e i n f o A classical problem in seismic tomography is the trade-off between a discontinuity location and the velocity of the medium. For that reason, crustal tomography and Pn tomography are typically done separately by isolating first-arriving Pg and Pn waves. Although this avoids the contamination of secondary arrivals because of the existence of the Moho, lots of good data are d...
