Abstract. Megathrust earthquakes and their tsunamis are some of the most destructive natural disasters in the world. A megathrust earthquake occurs at subduction zones at destructive convergent plate boundaries, where one tectonic plate is forced underneath another. Shallow slip cannot be resolved if the observation coverage of the offshore segment is <50%. It is a megathrust, located at a convergent plate boundary where it forms the interface between the overriding Eurasian plate and the subducting Indo-Australian plate. People had flocked to the warm water and beaches of Thailand, Sri Lanka and Indonesia. The tremor with an estimated moment magnitude (Mw) 6.9 occurred at 11:33 UTC. • In the 2010 rupture area conjugate thrusts bound pop-ups branched on the megathrust, • Propagation of coseismic slip onto the thrusts generates extrusion of pop-ups. The methodology is demonstrated by applying it to 79 global subduction zones defined in the literature, including Cascadia. The worst-case scenario, in which the two megathrust segments spanning Java rupture simultaneously, shows that tsunami heights can reach ~ 20 m and ~ 12 m on the south coast of West and East Java, respectively, with an average maximum height of 4.5 m along the entire south coast of Java. ‐ Spontaneous earthquake nucleation: slip episodes occur spontaneously when elastic stress overcomes the frictional strength of the megathrust locally (i.e., there is no external triggering).  |  doi: 10.1038/ngeo1119.
