- Coseismic displacements in Line-of-sight (LOS) direction were measured
as changes of range between ground suface and the satellite at the West
sky. The maximum displacement is about -2 m, which is displacement toword
the satellite.
- There are two discontinuities of phase in Pagai island (Pulau Pagai), as
shown in the broken lcurves. Some field survey team will probably find
surface rupture. The rupture should not be the earthquake source fault.
- Emergence due to uplift was observed in South Pagai island (Pulau Pagai
Selatan).
