Landslide threat to Pakistan earthquake survivors

14.02.2006


A landslide expert at Durham University, UK, is warning that further disasters are waiting to happen in North Pakistan because of the unstable ground conditions created by last October’s earthquake.



Professor Dave Petley, of the International Landslide Centre in Durham’s top-rated Geography Department, has returned from the earthquake zone after a reconnaissance mission with an US colleague. They have sent an urgent report to the Pakistan authorities with warnings and a list of actions required.

He says: “Although the national and international response to the disaster has been highly impressive there is a real need for the international community to take steps to help national organisations to prevent further tragedies in the coming months. The camps where people have lived since the earthquake could be hit by further landslips dislodged by the summer rains.”


The report warns about:

- A massive rock landslide in the Hattian area that has blocked two valleys to a depth of 250 metres. It was probably the largest earthquake-triggered landslip anywhere in the world during 2005. Two lakes are forming behind it and pose a serious threat. Previous studies show that 70 % of such landslide dams collapse and fail. Prof Petley recommends quick action to assess the stability of the dam, and the creation of a spillway to channel water safely before the July monsoons fill the lakes, causing overflow and possible collapse of the dam with potentially disastrous results.

- many other slopes in the area, left cracked and unstable by the earthquake. Monitoring equipment should be installed as soon as possible to assess the hazard. It may be advisable to move people out of some areas during the monsoon season.

- some of the tented villages for refugees built on the low terraces and ’alluvial fans’. These, say Prof Petley, are "highly dangerous positions". They are located at the bottom of slopes and close to rivers. The report adds: "These are near-perfect conditions for the generation of debris flows and flash-floods. Clearly the resistance of the tented villages to such events is effectively nil. We anticipate the potential for large-scale loss of life if this issue is not addressed."

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
