    Description: The German-Indonesian Tsunami Early Warning System (GITEWS) has been established after the devastating Tsunami in the Indian Ocean on December 26, 2004. It became an integral part of the Indonesian Tsunami Early Warning System (InaTEWS) providing sensor networks and core computational components. GITEWS follows an “end-to-end” approach to cover the complete warning chain from rapid hazard detection over decision support to capacity development of communities at risk and the implementation of disaster reduction measures. PROTECTS (Project for Training, Education and Consulting for Tsunami Early Warning Systems) followed GITEWS with its main focus on system refinements, capacity building, and elaborated training measures that covered all aspects of the GITEWS Project. This paper discusses the specific challenges of Tsunami Early Warning in Indonesia, describes recent developments in instrumentation and data analysis and summarizes the system performance over the past 5 years.

    Description: Fluvial fill terraces in intermontane basins are valuable geomorphic archives that can record tectonically and/or climatically driven changes of the Earth-surface process system. However, often the preservation of fill terrace sequences is incomplete and/or they may form far away from their source areas, complicating the identification of causal links between forcing mechanisms and landscape response, especially over multi-millennial timescales. The intermontane Toro Basin in the southern Central Andes exhibits at least five generations of fluvial terraces that have been sculpted into several-hundred-meter-thick Quaternary valley-fill conglomerates. New surface-exposure dating using nine cosmogenic 10Be depth profiles reveals the successive abandonment of these terraces with a 100 kyr cyclicity between 75 ±7and 487 ±34ka. Depositional ages of the conglomerates, determined by four 26Al/10Be burial samples and U–Pb zircon ages of three intercalated volcanic ash beds, range from 18 ±141to 936 ±170ka, indicating that there were multiple cut-and-fill episodes. Although the initial onset of aggradation at ∼1 Ma and the overall net incision since ca. 500 ka can be linked to tectonic processes at the narrow basin outlet, the superimposed 100 kyr cycles of aggradation and incision are best explained by eccentricity-driven climate change. Within these cycles, the onset of river incision can be correlated with global cold periods and enhanced humid phases recorded in paleoclimate archives on the adjacent Bolivian Altiplano, whereas deposition occurred mainly during more arid phases on the Altiplano and global interglacial periods. We suggest that enhanced runoff during global cold phases – due to increased regional precipitation rates, reduced evapotranspiration, or both – resulted in an increased sediment-transport capacity in the Toro Basin, which outweighed any possible increases in upstream sediment supply and thus triggered incision. Compared with two nearby basins that record precessional (21-kyr) and long-eccentricity (400-kyr) forcing within sedimentary and geomorphic archives, the recorded cyclicity scales with the square of the drainage basin length.

    Description: On November 12, 2017, a large earthquake (Mw = 7.3) hit Kermanshah province of Iran near the border of Iran and Iraq. At least 600 people were killed, 9000 injured and thousands left homeless. In this study we integrated observations from radar and optical remote sensing, seismology and field mapping to investigate source parameters, coseismically triggered slope failures and secondary faulting related to the Mw 7.3, Sarpol-e Zahab earthquake in Iran. Coseismic surface deformation was constrained by interferometric synthetic aperture radar (InSAR) analysis from SAR images obtained by L-band ALOS-2 and C-band Sentinel-1 satellites. ALOS-2 wide-swath (WS) interferograms were derived from ascending and descending orbits covering 09.08.2016-14.11.2017 and 04.10.2017-15.11.2017 time periods, respectively. Sentinel-1 TOPS coseismic interferograms were derived from ascending and descending orbits covering 11.11.2017-17.11.2017 and 12.11.2017-18.11.2017, respectively. Source parameters and slip models of the earthquake were then obtained by the Bayesian inversion of interferometric results using elastic dislocation modeling, considering the seismic parameters as a priori information. Preliminary results of geodetic source modeling suggests that the 12 November 2017 Sarpol-e Zahab earthquake was generated by blind ENE oblique thrust faulting with an average slip of approximately 4 m at a depth between 17 and 22 km. The 2017 Sarpol-e Zahab event also triggered a lot of coseismic slope failures including landslides and rock falls, and secondary faulting. Their potential locations were initially assessed by identifying local phase changes and areas affected by loss of coherence in the interferograms. Moreover, large-scale analysis of horizontal surface displacements was performed by pixel-offset tracking using Sentinel-1 SAR images. The results were evaluated by expert interpretation based on optical Sentinel-2 data in combination with geological information and field investigations. Largest horizontal deformation was observed for a co-seismically triggered landslide which was further analyzed using optical PlanetScope data acquired one day apart right before and after the earthquake (12th and 13th of November). Pixel-based change detection allowed exact spatial delineation of the displaced block covering an area of about 4 km2. Cross-correlation analysis resulted in a spatially detailed derivation of horizontal movement vectors indicating displacements in the range from about 5 to 30 m. The results of this study have shown that a combination of various remote sensing methods with modelling and field investigations is required for gaining an improved understanding of surface processes caused by the Mw 7.3, Sarpol-e Zahab earthquake. Complementary analysis of radar and optical remote sensing has led to a more comprehensive assessment of various types of co-seismically induced surface changes occurring at different spatial scales. Such information can contribute to an improved spatial characterization of co-seismically activated geological structures. This is especially important in the context of seismic hazard assessment for scarcely investigated areas like the one affected by the Sarpol-e Zahab earthquake in the border region between Iran and Iraq.

    Description: The understanding of early agrarian economies and their impact on landscapes and natural environments has become a major goal of many large-scale projects. The shaping of cultural landscapes by the spread of agriculture, animal husbandry and the building of settlements has been the most influential development since the beginning of agriculture more than 10.000 years ago. Sessions: •Gathering, Cultivation and Domestication •Ethnobotanical approaches •Methods and Analytical Archaeobotany •Regional and Historical Archaeobotany •Origins of agriculture in the Near East.

    Description: The theme of the 15th ICRSS is “Polar Regions in Transformation – Climatic Change and Anthropogenic Pressures”. Earth’s Polar Regions, including high mountain regions outside the high latitudes, feature cold-climate environments characterized by unique landscapes, biota, and processes. Many of these features and dynamics are Cryosphere-driven and either are already subject to or have the potential for fundamental and rapid changes in a warming world. The myriad of Earth observation technologies provide crucial tools to understand and quantify these changes. The 15th ICRSS in Potsdam is the largest in the conference series to date: About 100 registered participants come from 16 countries, demonstrating the true international character of this otherwise intimate but focused polar symposium. Together, with an engaged Local Organizing Committee and the International Scientific Committee, we organized 10 scientific sessions with 61 oral and 38 poster presentations, covering nearly all fields of Cryosphere research as well as research on northern vegetation and polar oceanography. The symposium program will be headlined by an exciting set of 7 keynote speakers highlighting the scientific frontiers in our research fields.
