Quick inversion of the rupture process of the 2009 March 19 Tonga earthquake
We inverted the broadband seismic data of the Global Seismographic Network (GSN) and obtained the rupture process of the 2009 March 19 Tonga earthquake using the quick technique of the earthquake rupture process inversion soon after the earthquake occurred. Subsequently, more data were collected and the inversion was performed again. The main feature of the inverted result was in good agreement with that of the quick result. The moment magnitude is MW7. 8, the rupture duration time is about 70 s, and there are 3 slip-concentrated patches on the fault plane.
