A vague #tsunami was triggered yesterday in the Southern Atlantic at the South #SandwichIslands
Seismic data show a Mw7.5 #earthquake, but aftershocks and observed waves on various stations indicate a much larger (and probably more complex) mechanism.

Right now, it is unclear what actually happend. Aftershocks stretch almost 300km from North to South and tsunami waves of 0.2 - 0.7m have been recorded in the Southern Atlantic & Indian Ocean. Too much for "just" Mw7.5
To at least mimic the potential tsunami, a virtual earthquake was simulated with a wave pattern roughly corresponding to the observed water levels.
This virtual earthquake was estimated to be around Mw8.3 with a 210 km length and a maximum slip of 20m.
