Electromagnetic expression of axial magma chambers

open access: yesGeophysical Research Letters, 1989
The electrical conductivity of sea floor materials is a strong function of porosity, pore geometry, fluid content, temperature and percentage of partial melt. These material properties are particularly volatile near the midocean ridge. Tracking electromagnetic eddy currents generated on the sea floor as they diffuse across the ridge can provide images ...

Shallow magma chamber under the Wudalianchi Volcanic Field unveiled by seismic imaging with dense array

open access: yesGeophysical Research Letters, 2016
The Wudalianchi Volcano Field (WDF) is a typical intraplate volcano in northeast China with generation mechanism not yet well understood. As its last eruption was around 300 years ago, the present risk for volcano eruption is of particular public ...
