In recent years, the natural disasters such as tsunami, earthquake, fire, drought, flood and extreme weather frequently occurred worldwide. The dynamic monitoring and evaluation of the disasters become very important for timely emergency responses. Our fast and flexible data acquisition and analysis have supported many international disaster relief agencies for disaster preventions and mitigations.

Earthquake in Haiti


On 12 January 2010, at 17:53 local time (21:53 UTC), a magnitude 7.0 earthquake occurred approximately at 25km west of Port-au-Prince, Haiti¡¯s capital.

An urgent and high priority task was sent to the Beijing-1 satellite, at 14:43 UTC on 13 January 2010, a panchromatic image over the disaster affected areas was captured. The image showed that the buildings in the city were badly damaged; the presidential palace and many building collapsed; some public facilities in the west of Port-au-dock were severely damaged; the possible oil tank leakage between the capital city of Port au Prince and the town of L¨¦ogâne was identified. These results reflected the size of the affected areas and magnitude of the disaster in real time; consequently, provided realistic and effective spatial information for the international society to understand the status of the Haiti Earthquake.


Tsunami in Japan


The 9.0 magnitude earthquake occurred at 13:46 JST (05:46 UTC) on 11 March 2011 at the 130km east of the Oshika Peninsula of T¨­hoku, Japan. The earthquake also resulted in a major tsunami.
Through the comparison of the multi-spectrum images captured before and after the earthquake by the Beijing-1 satellite, the earthquake and tsunami affected areas in Japan were tracked and monitored. The analytical results showed the areas and regions severely affected by the earthquake and tsunami. It provided a great support for the international aid and disaster relief work.


Flooding in Thailand

Severe flooding occurred during the 2011 monsoon season in Thailand.

21AT initiated the emergency response immediately after the disaster. At 10:24am on 24th October, the first PAN remote sensing image of the flooded areas in Thailand was acquired successfully, sent to UNESCAP and APSCO and forwarded to the Thai government. It provided the important spatial information for the disaster relief and evaluation.

On 27th October2011, APSCO sent a letter to thank 21AT for providing the Beijing-1 satellite images of the flooded areas that were very helpful to the Thailand government in timely decisions on flooding control and disaster relief.
