Plasma waves naturally occur in the Earth's magnetosphere as an effect of its interaction with the solar wind. Seismological methods, such as normal-mode oscillations and signals travel time analysis, applied to plasma waves form the discipline of magnetoseismology and are diagnostic tools to sound our space environment.

Normal-mode magnetoseismology makes use of geomagnetic field line resonances detected by either ground-based magnetometers or satellites to infer the plasma mass density of the inner magnetosphere. Travel-time magnetoseismology concerns the propagation of impulsive signals and is used to remotely monitor sudden impulses excited by interplanetary shocks at the magnetopause or substorm onsets in the magnetotail.

This session will focus on both aspects of magnetoseismology that combined together can potentially bring to a global monitoring system of the magnetosphere. Studies based on ground-based and satellites observations, as well as simulations are welcome.
