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.

I'm curious to see more details on what actually happened down there and maybe some eye witnesses on the arriving tsunami wave (even though, it was mostly at night)
Data on increased water levels still coming in.
The #tsunami reached 10cm on #LaGomera, #Canaries, #Spain in t he North Atlantic and up to 20cm on #LaReunion, #France in the Indian Ocean.
Almost 10000 km from the #tsunami source location.
