The floods in Pakistan may have faded from the headlines in Europe, but unfortunately the impact continues, even though the rainfall events that caused them occurred more than a month ago. The most dramatic illustration of this is a set of satellite images collected by NASA using the MODIS instrument. This is an image of the area around Sukkur taken on 7th July, before the rainfall event that initiated the …

Unfortunately the Google Earth image resolution is low in this area, but you can see …

Chinagate has published a rather dramatic picture of the site: The interesting thing about this image is the very large (apparently 5 m high) retaining …
