The position of the earths tectonic plates is key, says Lehigh University seismologist
The location of the recent earthquake that triggered a deadly tsunami in the Indian Ocean came as no surprise to geologists, says Anne Meltzer, a world-renowned seismologist at Lehigh University. "Earthquakes like this one happen only once every 50 to 100 years and they happen in very specific locations," says Meltzer, who has supervised two major international seismology research projects in the Himalayas.
The earthquake that struck the Indonesian island of Sumatra on Dec. 26 occurred along a "subduction zone" where the Indian tectonic plate is being subducted, or pulled beneath, the Burma tectonic platelet, says Meltzer. The earths surface is covered by seven to nine major tectonic plates and a number of minor plates, or platelets. The plates – huge slabs of semi-solid rock beneath continents and oceans – vary in size from a few hundred to thousands of kilometers across and in thickness from 15km to 200km.

Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
