EPSS Professor Yin and his colleagues analysed modern and historical records of earthquakes in northern China. Mapping their locations revealed a 160-kilometre-long fault segment running through Tianjin, roughly 100 kilometers southeast of Beijing. This area has not experienced a major tremor for about 8,400 years, and the authors estimate that a quake of roughly magnitude 7.5 is either overdue or will strike in the next 2,000 to 3,000 years. Given the region's complex fault structure, however, other factors could explain the lack of major earthquakes, such as multiple smaller quakes releasing energy from the fault.
Graduate student Patrick Boehnke has just received the Eugene M. Shoemaker Impact Cratering Award. The prize is awarded to undergraduate or graduate students in the disciplines of geology, geophysics, geochemistry, astronomy, or biology for the study of impact craters, either on Earth or on the other solid bodies in the solar system. EPSS alumni Matt Mielicki also received this award.
Despite extensive studies on the occurrence and stability of carbonate-rich melts, physical properties (such as density, viscosity, and mobility) of carbonate melts have not been well understood. In a paper published in Nature Communications , Yoshio Kono, Dan Hummer, Abby Kavner, Craig Manning and colleagues report viscosities of calcite and natural dolomite melts up to 6.2 GPa using an advanced technique of viscosity measurement with ultrafast synchrotron X-ray imaging. The imaging rate of 1,000 frames per second (fps), more than 15 times faster than that of conventional X-ray radiography (typically 30 to 60 fps) in large volume presses, enables precise determination of very low viscosity values. This study reveals that viscosities of calcite and dolomite melts are surprisingly low: in the range of 0.006-0.010 Pa s. These low viscosity values are more similar to those of water than to silicate melts.
The SpinLab is featured on a popular fluid dynamics website. SPINLab scientists used a tank, a record player, and dye to create an exciting video that illustrates the formation of Taylor columns. These striking columns are fluid dynamics phenomenon that occur as fluid moves around an obstacle in a rotating system.
The Department of Earth, Planetary & Space Sciences seeks an assistant professor in geology. We encourage applicants from all sub-disciplines of geology but preference may be given to candidates with experience on both sides of the cover/bedrock interface or who complement existing strengths in tectonics, paleoclimate, geochronology, and sedimentology. Applicants should have a Ph.D. or equivalent in geological sciences or a related field. Selection will begin on October 1, 2014. Please include a curriculum vitae, list of publications, statement of teaching and research, names and email addresses of three referees, electronic copies of up to five significant publications, and a cover letter addressing how your experience fits the job description. Electronic applications should be directed to the Chair of the Geology/Surface Processes Search Committee at https://recruit.apo.ucla.edu/apply/JPF00331. Inquiries may be directed to firstname.lastname@example.org. The University of California is an Equal Opportunity/Affirmative Action Employer and has a commitment to enhance diversity in the geosciences at UCLA (see https://faculty.diversity.ucla.edu). Women and underrepresented minorities are encouraged to apply. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, disability, age or protected veteran status.

UCLA solicits applications for one or more Researchers at the Assistant or Associate level, in the field of experimental or theoretical Space Plasma Physics, at the Institute of Geophysics and Planetary Physics, Department of Earth, Planetary and Space Sciences. For more information about the institute visit: http://www.igpp.ucla.edu and about EPSS visit: http://www.epss.ucla.edu The institute's Space Physics Center carries out investigations of the solar wind, and the magnetospheres, ionospheres and atmospheres of the Earth and planets. The successful candidate will have completed significant independent research in space physics and/or have a strong track record in space hardware development. The primary responsibilities will be to conduct studies on key plasma physics questions in Earth’s magnetosphere, at the moon or in the solar wind using theory and/or simulation tools that will help in the analysis and interpretation of currently acquired data from the THEMIS and ARTEMIS missions, in conjunction with current (Van Allen Probes) and upcoming (MMS) missions. The successful candidate will participate actively in a diverse and broad space physics research environment across UCLA, spanning basic plasma theory, simulations, and experimental space physics. The successful candidate is expected to strengthen or complement UCLA's space borne, ground based or experimental research geared towards understanding of plasma phenomena at Earth, planets their moons and the Inner and Outer Heliosphere, and develop their own direction within a stimulating and highly dynamic environment. Candidates can apply at https://recruit.apo.ucla.edu/apply/JPF00364. They should include a full CV, a short statement of research interests, and names of three individuals familiar with their work. Applications received prior to November 1, 2014 will be given full consideration. Position will remain open until filled.
