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 Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) onboard the Advanced Land Observing Satellite (ALOS, "Daichi") at 0:28 on June 11, 2010 further to May 13, 2010 (JST).

Fig. 1 shows an observed image of AVNIR-2 at 0:28 on June 11, 2010 (JST). Although there are several clouds seems by white color in the image, there is no cloud in the capital Port-au-Prince and that ground could be seen. Fig. 1 assigned by channel 3, 2, 1 for red, green, blue colors as true color composite.

Fig. 2 shows the pan-sharpened images produced by both PRISM and AVNIR-2 images that were taken on June 11, 2010 (left) and January 24, 2010 (right), which was eleven days after earthquake.

Blue points shown by a red circle as example in left image taken on June 11, 2010 seem residential areas temporary housings of refugees build up. The yellow squared areas show that the places have large difference as shown in Figs. 3 and 4.

Fig. 3 shows enlarged images (1 km squares) around presidential palace, and upper red mark is presidential palace and lower red mark is a stadium near the palace. Several new buildings next to presidential palace were built, and temporary housings seem to thicken at the neighboring the place. The people taking shelters in the stadium move to the temporary housings built near the stadium. Tightly-packed blue points in Fig. 3 seem to be tightly-packed temporary housings as well as Fig. 2.

Fig. 4 shows the enlarged images of the harbor at Port-au-Prince. The red mark indicates that pier broken by the earthquake has been repaired. Also it shows that new docks were built and several ships docked. These are denoting that the land at the coast was reclaimed and new buildings were built thus Port-au-Prince recovers from the earthquake steadily.

Fig. 5 is animation of two images same with Fig. 2 taken on June 11, 2010 and January 24, 2010, and two images switch among one second. It indicates developments for five months from the earthquake in detail.
