  • Shallow crustal structure of the caldera of Axial Seamount, Juan de Fuca ridge

    Creator:
    van Heeswijk, Marijke
    Abstract:
    An airgun refraction line along the length of the caldera of Axial Seamount as recorded by three Ocean Bottom Seismometers has been analyzed using the tau-zeta inversion technique (Dorman and Jacobson, 1981). Five resulting velocity profiles show that the seismic velocities of the upper 1.4 km of the crust are...

  • Crustal structure and seismicity of the Gorda Ridge

    Solano-Borrego, Ariel E.
    Abstract:
    We have determined the seismic crustal structure of the northern part of the Gorda Ridge using signals generated by explosive charges and recorded on Ocean Bottom Seismometers. The shot pattern forms two parallel lines, one on the east flank and the other along the median valley. Inversion of the travel...
