VLF Waves in the Foreshock (6652 words) |
 | The most significant result of the imaging is the observation of a finite extent to the electron foreshock emissions, which we attribute to the scale size of the shock acting to restrict the availability of energetic electrons far from the shock. |
| Figure 5 indicates that the VLF waves in the ion foreshock are generated well downstream of where ion beams are expected to be present, rather they are observed where we might expect diffuse ions to be present. |
| This appears to be the case for the electron foreshock, where maps of the VLF emissions suggest that shock curvature limits the energization of the electrons. |

Foreshock - Wikipedia, the free encyclopedia (117 words) |
| A foreshock is a smaller earthquake preceding a much larger earthquake. |
| Reviews of data of past events and their foreshocks showed that they have a low number of aftershocks and high foreshock rates compared to continental strike-slip faults. |
