Currently, we use a rough and simple threshold mechanism to identify the tsunami potential
of an earthquake. If the location of the earthquake is inland, deeper than 100km, or has
a magnitude less than 5.5 then we don't consider the earthquake for any wave propagation
computation. However, if you think the earthquake is relevant for computation then you can
do so by using 'Modify and reprocess'.
Anyhow, in the near future we plan to use an
improved mechanism by adopting region dependent decision matrices defined by the UNESCO-IOC
ICGs, that is ICG/NEAMTWS, ICG/IOTWS, ICG/PTWS, and ICG/CARIBE EWS.
