Follow-up Observation of Haiti Earthquake by PRISM and AVNIR-2 onboard "Daichi" (ALOS) (3)

A magnitude 7.0 (10km depth of epicenter) earthquake occurred at Haiti in the Central America at 6:53 on January 13, 2010 (JST) or at 21:53 of January 12, 2010 (UTC). This caused great damage like collapse of building. The Japan Aerospace Exploration Agency (JAXA) had performed the observations to monitor the recovery state by the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) onboard the Advanced Land Observing Satellite (ALOS, "Daichi") at 0:29 on June 28, 2010 further to June 11, 2010 (JST).

Fig. 2 and 3 are animation of the pan-sharpened images produced by both PRISM and AVNIR-2 images that were taken on January 24, 2010, June 11, 2010 and June 28, 2010 to see variation through the period.

Fig. 2 is animation image of Carrefour that were taken on January 24, 2010, June 11, 2010 and June 28, 2010 switch among one second. It shows new buildings were built with in the 5 months. And it has scattered texture can be seen in urban area just after the earthquake but as the time passes it changed into clear compartments.

Fig. 3 is animation image of Mariani that were taken on January 24, 2010, June 11, 2010 and June 28, 2010 switch among one second. Variation in cropland can be found in the image and it suggests that people's life in Mariani becoming stable.

JAXA plans continuous observation of this area.

* The pan-sharpened image by both PRISM and AVNIR-2 image is pseudo-color one of 2.5 m ground resolution that is produced by PRISM with a 2.5-m spatial resolution and AVNIR-2 with a 10-m spatial resolution in multispectral region.
