Equipment Used -
GPS Garmin hand-held GPS units
receiver Topcon Hiper+ DGPS base station receiver and rover
LiDar Riegl Z420i LiDAR laser scanner
Notes -
The Iwate-Miyagi Nairiku Earthquake, 2008 epicenter is at 39.028333,140.88.
This earthquake occurred in the south of the inland of Iwate Prefecture
at 8:43 JST on Saturday morning, June 14 (23:43 UTC on June 13).
The JMA magnitude was estimated at Mj 7.2, and
the moment magnitude by USGS was at Mw 6.9.
Data collection used WGS84, ellipsoid heights.
Data accuracy for LiDAR is 3 to 5 cm.
Data accuracy for DGPS is less than 1 cm.
Data accuracy for GPS is 2 to 8 m.
No post-processing done to data.
