Damage Assessment of the 2011 Japanese Tsunami Using High-Resolution Satellite Data
Bibliographic record
Abstract
Department of Geography and Geoinformation Science / George Mason University / Fairfax / VA / USAIntroductionOn 11 March 2011 at 05:46 UTC, a massive Mw 9.0underwater earthquake occurred 70 km off the easterncoast of Japan. The location of the earthquake was trian-gulated by the United States Geological Survey (USGS) to38.322 N 142.369 E, and the hypocentre was computedto 32 km beneath the surface. Figure 1 shows a map ofthe earthquakes that occurred between 1 and 10 March2011 (a) and between 11 and 31 March 2011 (b). Theearthquake of 11 March generated a tsunami that rapidlyhit the eastern coast of Japan and propagated across thePacific Ocean to the western coast of the Americas. Atsunami warning was issued by the National Oceanic andAtmospheric Agency (NOAA) affecting all countries withcoastline along the Pacific.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
