Alaska: Fixing
the Fatal Flaw of Fairbanks by Ned Rozell - Natural
hazards were not on the minds of Alaska pioneers who hacked homesites
out of the wilderness that would later become Anchorage, Valdez,
and Fairbanks, but each city has a fatal flaw. Much of Anchorage
sits on soils that are unstable when shaken during an earthquake.
The same problem forced Valdez to move from the floodplain of
the Lowe River to a bedrock townsite after the 1964 earthquake.

danger-the flooding of the Chena River. - Read

World:
Burning
oil cloud above northern Iraq - A burning oil pipeline in
northern Iraq produced an immense cloud of black smoke that stretched
across thousands of square kilometres, in this image acquired
by Envisat's Medium Resolution Imaging Spectrometer.
The smoke cloud is visible in the centre of this image of the
alluvial plain occupied by the valley of the river Tigris (flowing
from the top centre of the image) and the Euphrates (flowing
from the top left corner).
The Medium Resolution Imaging
Spectrometer (MERIS) on ESA's Envisat environmental satellite
acquired the image on 30 August, the same day as the media reported
a fire affecting a segment of oil pipeline near the town of Hawija.
