  abstract  = {Especially for the last twenty years, the studies of Linguistic Landscapes (LLs) have been gaining the status as an autonomous linguistic discipline. The LL of a (mostly) geographically limited area - which consists of e.g. billboards, posters, shop signs, material for election campaigns, etc. - gives deep insights into the presence or absence of languages in that particular area. Thus, LL not only allows to conclude from the presence of a language to its dominance, but also from its absence to the oppression of minorities, above all in areas where minority languages should - demographically seen - be visible. The LLs of big cities are fruitful research areas due to the mass of linguistic data. The first part of this paper deals with the theoretical and practical research that has been conducted in LL studies so far. A summary of the theory, methodologies and different approaches is given. In the second part I apply the theoretical basis to my own case study. For this, the LLs of two shopping streets in different areas of Hong Kong were examined in 2010. It seems likely that the linguistic competence of English must be rather high in Hong Kong, due to the long-lasting influence of British culture and mentality and the official status of the language. The case study's results are based on empirical data showing the objectively visible presence of English in both examined areas, as well as on two surveys. Those were conducted both openly and anonymously. The surveys are a reinsurance measuring the level of linguistic competence of English in Hong Kong. That level was defined before by an analysis of the LL. Hence, this case study is a new approach to LL analysis which does not end with the description of its material composition (as have done most studies before), but which rather includes its creators by asking in what way people's actual linguistic competence is reflected in Hong Kong's LL.},

  abstract  = {The northward movement and collision of the Arabian plate with Eurasia generates compressive stresses and resulting shortening in Iran. Within the Alborz Mountains, North Iran, a complex and not well understood system of strike-slip and thrust faults accomodates a fundamental part of the NNE-SSW oriented shortening. On 28th of May 2004 the Mw 6.3 Baladeh earthquake hit the north-central Alborz Mountains. It is one of the rare and large events in this region in modern time and thus a seldom chance to study earthquake mechanisms and the local ongoing deformation processes. It also demonstrated the high vulnerability of this densily populated region.},

  abstract  = {The most recent intense earthquake swarm in the Vogtland lasted from 6 October 2008 until January 2009. Greatest magnitudes exceeded M3.5 several times in October making it the greatest swarm since 1985/86. In contrast to the swarms in 1985 and 2000, seismic moment release was concentrated near swarm onset. Focal area and temporal evolution are similar to the swarm in 2000. Work hypothysis: uprising upper-mantle fluids trigger swarm earthquakes at low stress level. To monitor the seismicity, the University of Potsdam operated a small aperture seismic array at 10 km epicentral distance between 18 October 2008 and 18 March 2009. Consisting of 12 seismic stations and 3 additional microphones, the array is capable of detecting earthquakes from larger to very low magnitudes (M<-1) as well as associated air waves. We use array techniques to determine properties of the incoming wavefield: noise, direct P and S waves, and converted phases.},

  abstract  = {Rapid and robust characterization of large earthquakes in terms of their spatial extent and temporal duration is of high importance for disaster mitigation and early warning applications. Backtracking of seismic P-waves was successfully used by several authors to image the rupture process of the great Sumatra earthquake (26.12.2004) using short period and broadband arrays. We follow here an approach of Walker et al. to backtrack and stack broadband waveforms from global network stations using traveltimes for a global Earth model to obtain the overall spatio-temporal development of the energy radiation of large earthquakes in a quick and robust way. We present results for selected events with well studied source processes (Kokoxili 14.11.2001, Tokachi-Oki 25.09.2003, Nias 28.03.2005). Further, we apply the technique in a semi-real time fashion to broadband data of earthquakes with a broadband magnitude >= 7 (roughly corresponding to Mw 6.5). Processing is based on first automatic detection messages from the GEOFON extended virtual network (GEVN).},

  abstract  = {Receiver functions are a good tool to investigate the seismotectonic structure beneath the a seismic station. In this study we apply the method to stations situated on or near Sumatra to find constraints on a more detailed velocity model which should improve earthquake localisation. We estimate shallow Moho-depths (~ 21 km) close to the trench and depths of ~30 km at greater distances. First evidences for the dip direction of the slab of ~60° are provided. Receiver functions were calculated for 20 stations for altogether 110 earthquakes in the distance range between 30° and 95° from the receiver. However the number of receiver functions per station is strongly variable as it depends on the installation date, the signal-to-noise-ratio of the station and the reliability of the acquisition.},

  abstract  = {An der Universit{\"a}t Potsdam wird seit 2008 ein automatisiertes Verfahren angewandt, um Bruchparamter großer Erdbeben in quasi-Echtzeit, d.h. wenige Minuten nachdem sich das Beben ereignet hat, zu bestimmen und der {\"O}ffentlichkeit via Internet zur Verf{\"u}gung zu stellen. Es ist vorgesehen, das System in das Deutsch-Indonesische Tsunamifr{\"u}hwarnsystem (GITEWS) zu integrieren, f{\"u}r das es speziell konfiguriert ist. Wir bestimmen insbesondere die Dauer und die Ausdehnung des Erdbebens, sowie dessen Bruchgeschwindigkeit und -richtung. Dabei benutzen wir die Seismogramme der zuerst eintreffenden P Wellen vom Breitbandstationen in teleseimischer Entfernung vom Beben sowie herk{\"o}mmliche Arrayverfahren in teilweise modifizierter Form. Die Semblance wir als {\"A}hnlichkeitsmaß verwendet, um Seismogramme eines Stationsnetzes zu vergleichen. Im Falle eines Erdbebens ist die Semblance unter Ber{\"u}cksichtigung des Hypozentrums zur Herdzeit und w{\"a}hrend des Bruchvorgangs deutlich zeitlich und r{\"a}umlich erh{\"o}ht und konzentriert. Indem wir die Ergebnisse verschiedener Stationsnetzwerke kombinieren, erreichen wir Unabh{\"a}ngigkeit von der Herdcharakteristik und eine raum-zeitliche Aufl{\"o}sung, die es erlaubt die o.g. Parameter abzuleiten. In unserem Beitrag skizzieren wir die Methode. Anhand der beiden M8.0 Benkulu Erdbeben (Sumatra, Indonesien) vom 12.09.2007 und dem M8.0 Sichuan Ereignis (China) vom 12.05.2008 demonstrieren wir Aufl{\"o}sungsm{\"o}glichkeiten und vergleichen die Ergebnisse der automatisierten Echtzeitanwendung mit nachtr{\"a}glichen Berechnungen. Weiterhin stellen wir eine Internetseite zur Verf{\"u}gung, die die Ergebnisse pr{\"a}sentiert und animiert. Diese kann z.B. in geowissenschaftlichen Einrichtungen an Computerterminals gezeigt werden.
