Seismic Structure And Seismicity Of The Cooling Lava Lake Of Kilauea Iki, Hawaii
Journal Article: Seismic Structure And Seismicity Of The Cooling Lava Lake Of Kilauea Iki, Hawaii
AbstractThe use of multiple methods is indispensable for the determination of the seismic properties of a complex body such as a partially solidified lava lake. The combined results from various active and passive experiments conducted on Kilauea Iki in March 1976 suggest a rather thin (less than 10 m) zone of residual melt, the lateral extent of which is delineated by a sharp drop in the activity of seismic events occurring within the crust of the lake. The heavily fractured crust is characterized by P velocities ranging from 0.8 to 2.2 km/s and the P velocity could be even lower in the melt possibly because of the presence of gas bubbles. The present seismicity of the lake is compatible with the formation of tensile cracks caused by contraction due to cooling.
