In the Nepal earthquake, two stations were compared with a KATN accelerograph as relatively co-located--the distance between sensors was 6 km (NAST) and 10 km (KKN4), but with a similar epicentral azimuth.
Station KKN4 is situated further from KATN than NAST, but closer to the epicentre.
The next group includes 3 GPS stations (KKN4, NAST, SNDL) and the accelerograph (KATN) located on the top of the fault zone or to the south, slightly outside the source area.
