Generation of supersonic solitions by earthquake emission in the van Allen rediation belt
MetadataShow full item record
The parametric coupling between earthquake emitted circularly polarized electromagnetic radiation and ponderomotively driven ion-acoustic perturbations in the Van Allen Radiation Belt is considered. A cubic nonlinear Schrödinger equation for the modulated radiation envelope is derived, and then solved analytically. Supersonic solitons are found to be generated in the Van Allen Belt which can be a tool for the prediction of a massive earthquake to be followed.
