2011 Tohoku Earthquake: Dataset

PPP Kinamatic Solution for the Great Tohoku Earthquake, M9.0
1Hz Post-processing with Global Satellite Clock Estimated with Real-time

April 5, 2011

1Hz GEONET data provided by the Geospatial Information Authority of Japan (GSI) via Nippon GPS Data Services Company (NGDS), were post-processed in real-time mode with realtime orbits and clock corrections from the VERIPOS/APEX global service. GPS Solutions' RTNet software was used for the PPP analysis and is also used for APEX service.
