The Integration of Dakwah in Journalism: Peace Journalism

This article discusses the integration of Islam, particularly da’wa, with peace journalism. It argues that Islamic communication is basically peace journalism. Islamic communication consists of tabligh (information), taghyir (so–cial change), khairu ummah (exemplary community), and akhlaq al-karimah (noble behavior, civil society), the purpo–se of which is to perpetuate conflict sensitivity, constructive conflict, and conflict resolution. Muslim journalists can produce articles about Islam to promote Islamic teachings relevant to universal values, including inclusiveness for humanity values which are inclusive. It is important for Muslims to create a platform for sharing information and religious values that can be discussed by audiences.Keywords: Integration of Dakwah in journalism, peace journalism----------------------------------------------------------------------Artikel ini mengulas integrasi Islam, khusunya dakwah, dengan jurnalistik damai (peace journalism). Penulis perpandangan bahwa pada dasarnya, komunikasi Islam adalah jurnalistik perdamaian (peace journalism). Sebab komunikasi Islam terdiri daripada tabligh, taghyir, khairu ummah dan akhlak al- karimah, yang bertujuan untuk membangun kepekaan sosial, perdamaian, dan resolusi konflik. Pula Peace journalism menggambarkan nilai-nilai universal dan inklusif, seperti keadilan, keamanan, kesela–matan, keharmonian, toleransi, hormat kepada semua manusia sebagaimana diajarkan oleh Islam. Oleh karennya, jurnalis Muslim dapat bekerja di media Islam dan meng–hasilkan karya-karya tulisan tentang nilai-nilai Islam yang inklusif. Hal ini penting bagi umat Islam untuk membuat platform untuk berbagi informasi dan nilai-nilai agama yang dapat didiskusikan.Kata Kunci: integrasi dakwah dalam jurnalistik, jurnalistik dama

Joint inversion of seismic and electric data applied to 2D media

Methods based on the seismic P-wave, seismic surface wave, and apparent resistivity are commonly used in the solution of several near-surface problems. However, the solution nonuniqueness and the intrinsic limitations of these methods can cause inconsistency in the final results. Dispersion curves of surface waves, P-wave traveltimes, and apparent-resistivity data were jointly inverted to obtain internally consistent and more reliable final model of P- and S-wave velocities and resistivity. A collection of 1D layered models was obtained by a deterministic joint inversion algorithm based on the laterally constrained inversion scheme. The three data sets were jointly inverted imposing the same structure and Poisson’s ratio was introduced as a physical link between P- and S-wave velocities to better constrain the inversion. No physical link was imposed between the resistivity and the seismic velocities. The inversion algorithm was tested on synthetic data and then applied to a field case, where benchmark borehole data were available. The synthetic and field examples provided results in agreement with the true model and the existing geologic information, respectively

Seismic expression of shear zones: Insights from 2-D point-spread-function based convolution modelling

Shear zones are common strain localization structures in the middle and lower crust and play a major role during orogeny, transcurrent movements and rifting alike. Our understanding of crustal deformation depends on our ability to recognize and map shear zones in the subsurface, yet the exact signatures of shear zones in seismic reflection data are not well constrained. To advance our understanding, we simulate how three outcrop examples of shear zones (Holsnøy - Norway, Cap de Creus - Spain, Borborema - Brazil) would look in different types of seismic reflection data using 2-D point-spread-function (PSF)-based convolution modelling, where PSF is the elementary response of diffraction points in seismic imaging. We explore how geological properties (e.g. shear zone size and dip) and imaging effects (e.g. frequency, resolution, illumination) control the seismic signatures of shear zones. Our models show three consistent seismic characteristics of shear zones: (1) multiple, inclined reflections, (2) converging reflections, and (3) cross-cutting reflections that can help interpreters recognize these structures with confidence.publishedVersio

Seismic Monitoring of Permafrost in Svalbard, Arctic Norway

We analyze data from passive and active seismic experiments conducted in the Adventdalen valley of Svalbard in the Norwegian Arctic. Our objective is to characterize the ambient wavefield of the region and to investigate permafrost dynamics through estimates of seismic velocity variations. We are motivated by a need for early geophysical detection of potentially hazardous changes to permafrost stability. We draw upon several data sources to constrain various aspects of seismic wave propagation in Adventdalen. We use f-k analysis of five years of continuous data from the Spitsbergen seismic array (SPITS) to demonstrate that ambient seismic noise on Svalbard consists of continuously present body waves and intermittent surface waves appearing at regular intervals. A change in wavefield direction accompanies the sudden onset of surface waves when the average temperature rises above the freezing point, suggesting a cryogenic origin. This hypothesis is supported further by our analysis of records from a temporary broadband network, which indicates that the background wavefield is dominated by icequakes. Synthetic Green's functions calculated from a 3D velocity model match well with empirical Green's functions constructed from the recorded ambient seismic noise. We use a shallow shear-wave velocity model, obtained from active seismic measurements, to estimate the maximum depth of Rayleigh wave sensitivity to changes in shear velocity to be in the 50-100 m range. We extract seasonal variations in seismic velocities from ambient noise cross-correlation functions computed over three years of SPITS data. We attribute relative velocity variations to changes in the ice content of the shallow (2-4 m depth) permafrost, which is sensitive to seasonal temperature changes. A linear decreasing trend in seismic velocity is observed over the years, most likely due to permafrost warming.Peer reviewe
