Mangroves reduce Tsunami impacts

01.02.2012
An analysis of earthquake and tsunami risks presented this month in the Pertanika Journal of Science & Technology suggests that mangrove forests have a protective role in the event of a tsunami.
The researchers, from the newly formed Disaster Research Nexus (DRN) at Universiti Sains Malaysia, hope that their work will encourage the development of better prepared communities.

The 2004 Banda Aceh earthquake and ensuing Andaman mega tsunami that caused widespread devastation and killed over a quarter of a million people worldwide was a wake-up call to many. Immediately afterwards, work was initiated to help develop human capacity and resources, and to mitigate future events. Koh Hock Lye and colleagues at the DRN developed a tsunami simulation model to investigate the role of coastal vegetation in reducing the impact of such events.
Using the model, the team analysed the earthquake risk for the Upper Padas Dam in Sabah, and found that the presence of mangroves appeared to reduce the impact of tsunamis. The research also showed that tsunamis can affect the salinity of water and soil and induce vegetative changes in affected regions.

Mangrove forests are one of the world’s most threatened ecosystems, with a fifth of the world’s mangroves having been destroyed over the last few decades. This research highlights the need to conserve them in areas where the risk of earthquakes and tsunamis are high.

The team hope that their work will improve research collaboration and allow better preparedness for seismic events worldwide.

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
