Occasionally I post a round up of stories on natural hazards, mostly on landslides, that have caught my eye in the last few days. Here is the latest set: 1.

This image was captured by the ALI instrument on 18th September: Compare this with an image taken of the same area just three days earlier: Or the Google Earth image of the same area, which was collected in May this year: Geo-TV, …

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.

The floods in Pakistan continue to extend to new areas, increasing the magnitude of the impact on a daily basis. The PakMet hydrographs continue to show increasing flow levels. At Guddu the discharge is still rising, and is now close to the peak level reached in the first flood wave (click on “read more” to reveal the rest of this post): Meanwhile, as expected serious problems are developing in the area of …

The flood crisis in Pakistan continues to develop with a surprising pace. In an earlier post I suggested that this event might be Pakistan’s equivalent of Hurricane Katrina (i.e. a wake-up call for effective disaster management), but now it is starting to look more like the equivalent of the Haiti Earthquake – i.e. an event that is so catastrophic that the coping capacity of the state is exceeded. There is …
