    This will be complemented by measurements from ground based observatories SAMBA CARISMA THEMIS ground ENIGMA arrays and INTERMAGNET network Basic derived quantities of our analysis will include wavelet power spectra E B wave peak frequency and amplitude wave occurrence duration and timing with regard to major magnetospheric phenomena like storms substorms radiation belt enhancements Since ULF waves influence strongly the Earth s magnetospheric dynamics they are of particular relevance for space weather nowcasting and forecasting efforts This project will focus on the central role that ULF waves in the dynamics of the outer radiation belt through particle energization scattering and transport across the magnetic field lines The results of the waves analysis and in particular the characteristics of the ULF wave propagation will be used to advance the current understanding of the radiation belt wave environment Such information is crucial for modeling wave particle interactions In the preparation phase of Swarm the analysis of specific ULF waves can help understand the processes that play a crucial role in generating the waves with specific propagation characteristics The latter is expected to be coupled with radiation belts and ring currents Present day data from CHAMP Cluster and THEMIS can be used to

    in near field local conditions where the travel time of the first tsunami wave is very short that is less than 30 minutes which is a typical case in the North East Atlantic and the Mediterranean Sea region but also elsewhere around the globe The operational condition that should be fulfilled is that the time of tsunami detection plus the time of warning transmitting plus the time of evacuation should not exceed the travel time of the first tsunami wave from its source to the closest evacuation zone To this goal the time to detect of the causative earthquake should be compressed at the very minimum In this context the core of the proposed system is a network of seismic early warning devices which activate and send alert in a few seconds after the generation of a near field earthquake when a seismic ground motion exceeding a prescribed threshold is detected Then civil protection mobilizes to manage the earthquake crisis but also to detect and manage a possible tsunami through a Geographical Risk Management System For the tsunami detection the system is supported by tide gauges of radar type a data base of pre simulated tsunami scenarios and a local
