Last but not least, the joint doctoral programme helps promote additional networking: What is more, leading minds from several institutions in the field of life sciences have joined forces in the Max Planck School Matter to Life — the new nationwide format for doctoral training in Germany. He will speak on the subject: On the following two days, the governing bodies of the Max Planck Society will meet in the Kongresshaus.

I will then review a series of friction experiments at hydrothermal conditions in which serpentinite gouge sheared between quartz-bearing rocks weakens and slides stably, in contrast to the relatively strong and potentially unstable behavior of serpentinite in an ultramafic chemical setting.

He and his students explore the influences of place, culture, and affect on modes of teaching and inquiry in the Earth sciences. Much of their research focuses on geologically and culturally diverse regions of the Southwest U. They also work with interpretive professionals and the public at several U. The goal of his group is to apply research-tested, place-based and culturally infused teaching methods to foster public Earth science literacy, greater diversity in the geoscience community, and environmental and cultural sustainability in their study regions.

He is most interested in assisting educators, students, and the public to leverage their personal and cultural connections to places and landscapes in order to improve geoscience literacy for all. EarthScope Education and Outreach: Transcontinental, yet Place-Based All regions of the United States have interesting and instructive geodynamic and geomorphic histories, but many also have limited exposures: The unprecedented detail about transcontinental crustal and mantle structure and dynamics now revealed by the EarthScope Program can help bring local geologic stories to life for teachers and students, and help foster place-based PB teaching: PB teaching is applicable to classroom, lab, and field instruction and to free-choice teaching interpretation practiced in parks and museums.

PB geoscience learners construct knowledge by engaging with accessible and familiar Earth features, processes, and history; and exploring geoscientific controls on local and regional environmental and sociocultural sustainability and public safety.

Education research increasingly supports the use of PB teaching to motivate interest and foster scientific literacy in more diverse learners including underrepresented minority students as well as the general public. EarthScope researchers and educators from Virginia to Alaska are themselves developing and disseminating resources and programs intended to share locally relevant geoscientific findings with educators and the public, and many illustrative examples are now available to apply or use as templates for PB geoscience teaching.

This presentation draws on a range of projects, resources, and evaluations for PB education and outreach conducted nationwide by the EarthScope Program, but it can be tailored to accommodate the place- or region-specific interests of host institutions in infusing EarthScope science and PB teaching methods into their own programs in geoscience education, interpretation, public outreach, or K teacher or interpreter professional development in the Earth sciences.

Her work focuses on better understanding slow slip processes, deep fault rheology, and fault friction. Roland Burgmann on slow earthquakes and fault rheology. Her ongoing projects include using models of fault friction to understand secondary slip fronts that occur during slow slip events, estimating strong ground motion in Cascadia, and using Nodal seismometers to better understand the seismic source and site response. Low-Frequency Earthquakes Low-frequency earthquakes LFEs are small repeating earthquakes that occur in conjunction with deep slow slip.

Like typical earthquakes LFEs are thought to represent shear slip on crustal faults but when compared to earthquakes of the same magnitude LFEs have lower corner frequencies, implying longer durations, and are depleted in high-frequency content relative to earthquakes of similar magnitude. In Cascadia, we correct LFE waveforms for path effects and use the resulting source time functions to calculate LFE duration and magnitude.

We use these estimates to show that, like Parkfield, LFEs in Cascadia also have low stress drops, rupture and slip velocities. We also find that LFE duration displays a weaker dependence upon moment than expected for self-similarity, suggesting that LFE asperities are limited in dimension and that moment variation is dominated by slip. This behavior implies that LFEs exhibit a scaling distinct from both large-scale slow earthquakes and regular seismicity.

Together the slow rupture velocity, low stress drops, and slow slip velocity explain why LFEs are depleted in high frequency content relative to ordinary earthquakes and suggest that LFE asperities represent areas capable of relatively higher slip speed in deep fault zones. Heather DeShon is a seismologist at Southern Methodist University whose research focuses on understanding earthquake initiation and rupture complexity.

She uses high-resolution earthquake relocation and tomography to explore the spatial and temporal relationships between seismic source characteristics and structural variability. Her background in using local amphibious seismic networks to understand subduction seismogenic zone processes has more recently been applied to studies of intraplate seismicity and lithospheric structure in the central US. More broadly, her research interests are aimed at improving the characterization of seismic and tsunami hazard.

Heather received her B. Death of a Fault: A Comparison of Seismicity in the New Madrid Seismic Zone and North Texas Increased seismicity rates across the central United States have raised scientific questions and local and national concerns about the impact of shale gas production on infrastructure and subsurface structures such as faults.

But the central US is not historically aseismic and intraplate faulting is not uncommon. Both New Madrid seismicity and North Texas earthquakes occur along reactivated ancient faults located in the basement granites and overlying sedimentary units and release natural tectonic stresses. New Madrid has a long paleoseismic record of large earthquakes.

Science Outside the Lab

High-resolution earthquake locations, waveform correlation, and source characteristics are combined with information on subsurface geology and fault structure, and 3D pore pressure modeling to provide insight into the relationship between fluid migration at depth and modern microseismicity along pre-existing fault structures. Comparisons of potentially induced sequences like North Texas with natural intraplate seismic zones like New Madrid may yield important insights to understanding the long-term hazard associated with the increased seismicity in the Central US.

His work aims to describe how the shape of Earth's surface is changing at timescales of seconds to decades, and to link observed change to geophysical processes associated with phenomena ranging from earthquakes to climate change.

Borsa's expertise includes the collection and analysis of geodetic data from many sources, including permanent and mobile GPS sensors, airborne lidar, and satellite altimeters. He is also actively involved in the calibration and validation of elevation measurements from several generations of satellite altimeters, and has made the remote salar de Uyuni in Bolivia his field home for the past decade in support of this work.

Borsa took an atypical route to science, beginning with a B. He returned to Scripps and to full-time scientific research in What EarthScope's Plate Boundary Observatory can tell us about water resources in the western United State Following a year of above-average precipitation inthe western United States entered into drought in late and has yet to emerge.

The severity of the current drought is focusing public attention on known water resource challenges in the West and is changing assumptions about how water use should be monitored and regulated. Despite this new interest in water management, snowpack and groundwater — key components of water storage — are sparsely instrumented and cannot yet be adequately monitored from space.

As a result, a new paradigm is emerging for observing water in the western US. Because the solid earth responds elastically to hydrological loading, changes in water storage can be inferred from surface displacements measured using the Global Positioning System GPS.

Seasonal changes in water loading have long been known to drive annual cycles of GPS site motion, but changes over both longer and shorter periods are detectable and yield insights into weather and climate phenomena from individual storms to multiyear drought. Scientific GPS networks such as the Plate Boundary Observatory, originally built to study crustal displacement from plate tectonics and volcanic processes, could soon become an important extension of the global hydrological observing system.

The main focus of his research is developing innovative seismic interferometry and array processing techniques to extract new information that can be used to constrain the structure of the earth, from the surface to the core. After receiving his B. Michael Ritzwoller on ambient noise and surface wave tomography. Victory Tsai and Robert Clayton. Inhe received the Charles F.

His ongoing projects include imaging the Yellowstone magma plumbing system, fault zone structure, shallow crustal structure, and inner core structure using seismic interferometry and seismic tomography. The unprecedented amount of high quality broadband seismic data allows seismologists to image detailed earth structure on various different scales from shallow to deep.

In particular, innovative seismic analyzing techniques have been developed to better utilize the array configuration and to extract new constraints on the structure of the earth that were not available before. In this presentation, I will first discuss some of the recent developments in seismic interferometry and tomography.

I will explain how seismologists can now extract useful seismic signals from diffusive wavefields, such as the ambient noise wavefield and the earthquake coda wavefield. She is interested in the mechanical and fluid transport properties of fault zones using methods from experimental rock deformation and structural geology with particular concern for constraining seismic hazards.

Her work is focused on determining how mechanical properties, fluid flow, and rock fabric lead to diverse fault slip behavior. Melodie received her B.

Creep and the potential for seismicity along the central segment of the San Andreas Fault The central segment of the San Andreas Fault SAF currently accommodates displacement by a combination of aseismic creep and microseismicty. In the past, earthquakes on the adjacent locked segments of the SAF have arrested at the boundaries of the creeping segment, indicating that it is a barrier to rupture propagation.

Although historically aseismic, we still do not know whether a sufficiently large rupture could initiate on a locked segment and propagate into and through the creeping segment of the SAF. I present results from deformation experiments conducted on gouge from the CDZ at shear rates that range from in-situ creep to seismic slip.

The strength of the gouge varies with shear rate and this strength variation reflects an evolution in deformation processes that is recorded in the microstructure of the sheared gouge. I will discuss how the mechanical and microstructural properties are critical to constraining the potential for seismic slip along the creeping segment of the SAF.

Finally, I will discuss how results from the SAFOD community have revealed the long-term evolution and seismic cycles of creeping plate boundary faults. Watch a video of her talk at Marshall University in November Dr. His research interests center around understanding how deformation is distributed spatially in plate boundary zones, and temporally through the seismic cycle associated with individual structures.

For the shorter time scale, Reed uses historical leveling and tide gauge observations as well as GPS and satellite altimetry to measure vertical deformation rates. He uses high resolution observations of topography coupled with Quaternary dating methods to measure deformation rates averaged over multiple seismic cycles. Reed's group is working along the west coast of the U. He received a B. He then worked as post-doctoral researcher at the University of Tasmania, applying satellite geodesy to questions of crustal deformation, sea level rise, and Antarctic ice sheet mass balance.

He joined the faculty of New Mexico State University in Ups and downs of the U. Implications of eight decades of vertical deformation measurements for seismic hazards and sea level impacts Along active plate boundaries, vertical deformation of the crust results from strain accumulation between major earthquakes.

Observations of this vertical deformation are important to constrain where faults are currently locked and may slip in future earthquakes, particularly when integrated with horizontal deformation imaged by GPS. Additionally, the vertical motion of the land along the coast can either enhance or counteract the effects of the global process of sea level rise on a local basis.

In this presentation, I will show how observations of relative sea level change made at tide gauges and repeated leveling surveys can be used to measure the pattern and rate of vertical deformation over timescales of several decades to over a century. I will also review satellite-based estimates of vertical deformation and sea level rise made over the past two decades to assess the level of agreement between techniques and examine changes in deformation rates over time.

Tectonic deformation is the dominant signal along the Cascadia portion of the coast, and is consistent with along-strike variation in locking behavior on the plate interface.

Rates of vertical motion are lower along the transform portion of the plate boundary and include anthropogenic effects, but there are significant tectonic signals, particularly in the western Transverse Ranges where the crust is shortening across reverse faults.

I will highlight emerging insights and outstanding questions derived from the vertical deformation rate field for understanding hazards from earthquakes and coastal inundation related to sea level rise.
