Alaskan Earthquake 'to be Expected,' Says Researcher

24.06.2009
As reports of a strong earthquake in Alaska continue to emerge today, a Baylor University earthquake researcher says this is not an unusual event in this area.

The U.S. Geological Survey said an earthquake with a magnitude of 5.4 struck near the town of Willow at 11:30 a.m. The epicenter was 58 miles from the state's largest city, Anchorage, where the rumbling continued for several moments, causing people to dive under desks and huddle in doorways.

Dr. Jay Pulliam, professor of geophysics at Baylor, says the earthquake took place where the Pacific tectonic plate is subducting beneath the North American plate.

"There have been many, many events there in the past so this is not an unusual event," Pulliam said. "It's also a remote region so the population density is extremely low."

Widely considered an expert in geophysics, Pulliam is leading a Baylor team that is playing host to two seismic stations as part of EarthScope, the largest geoscience project ever funded by the federal government. In addition, the Baylor scientists installed a 70-station network focused on the Rio Grande Rift, a rift valley extending north from Mexico, near El Paso, through New Mexico and into central Colorado. The program involves the National Science Foundation, the Incorporated Research Institutions for Seismology (IRIS), the U.S. Geological Survey, NASA and hundreds of geoscientists from universities around the country.

The Baylor researchers will use geophysical data generated by EarthScope and other projects to help them recognize potentially dangerous faults that can produce earthquakes and to learn about the processes by which our continent is evolving. The two reference seismograph stations that Baylor now hosts are among the hundreds of seismographs that contribute information to the national database. The two stations will be part of nearly 100 that remain behind to become permanent parts of the USGS's Advanced National Seismic System.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
