Disaster Evaluation

The 2010 eruptions of Eyjafjallajökull were volcanic events at Eyjafjallajökull in Iceland which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010. From 14–20 April, ash covered large areas of northern Europe when the volcano erupted. About 20 countries closed their airspace to commercial jet traffic and it affected about 10 million travellers.

Disaster Evaluation

Periodically monitoring the environment around the potential disaster areas can record and control changes in land condition. With onsite investigation over the focus area, environmental protection and prevention works (for example soil and water preservation) can be applied to such areas. From these comparison pictures, it clearly shows that there is significant ground collapsing at area A on November 12, 2004. There are also increasing size of barren lands along the Shang Ping River therefore water and soil preservation should be upgraded in these areas.
