The earthquake and tsunami that struck the north-eastern coast of Japan on 11 March, was a tragedy for the thousands of people who lost their lives and livelihoods. From the photos and videos documenting the devastation, it would have been difficult to imagine a worse outcome.
China will start building a test satellite later this month (April) to detect electromagnetic anomalies in the atmosphere, as part of the country's proposed earthquake monitoring network, and hopes to launch it in 2014.
Two 7.0 magnitude earthquakes stuck Myanmar on March 24. Earthquakes struck a relatively rural section of the country that borders on Thailand, Laos, and China. But these back to back disasters, earlier in Japan and now in Myanmar, prompted Chinese government will launch a campaign to map the country's active fault lines.
By spatially extensive events, ground-based mapping is too slow, typically hindered by disaster-related site access difficulties, or too dangerous as in the case of potential radioactive contamination resulting from the March 2011 earthquake and tsunami disaster in Japan.
Following the massive earthquake and tsunami that hit Japan on 11 March, satellite imagery has been vital in providing a clear picture of the extent of devastation to aid the relief effort now underway. In
The map shows the different amounts that Earth has moved as a result of the Magnitude 6.3 tremor that left more than 160 people dead.The image was created by the Japanese Alos spacecraft which is being used to survey the damage. It clearly shows that the worst of the damage was the south-eastern suburbs of the capital Christchurch - there the lines are closest together meaning the tremor came closest to breaking through the surface. The closer together the lines are on this image, the higher the ground has pushed towards the surface.
