Paasche, Hendrik; Eberle, Detlef; Das, Sonali; Cooper, Antony Kyle; Debba, Pravesh; Dietrich, Peter; Dudeni-Thlone, Nontembeko; Gläßer, Cornelia; Kijko, Andrzej; Knobloch, Andreas; Lausch, Angela; Meyer, Uwe; Smit, Ansie; Stettler, E. (Edgar Heinz); Werban, Ulrike (Springer, 2014-02)This article reflects discussions German and South African Earth scientists, statisticians and risk analysts had on occasion of two bilateral workshops on Data Integration Technologies for Earth System Modelling and ...
-
Smit, Ansie; Stein, Alfred; Kijko, Andrzej (Wiley, 2019-09)This study presents a method for estimating two area‐characteristic natural hazard recurrence parameters. The mean activity rate and the frequency–size power law exponent are estimated using Bayesian inference on combined ...
-
Pavlenko, V.A. (Vasily); Kijko, Andrzej (Springer, 2019-06)This study examines the effect of the procedures used in three different probabilistic seismic hazard analysis (PSHA) methods for estimating the rates of exceedance of ground motion. To evaluate the effect of these procedures, ...

Pule, T.; Fourie, C.J.S.; Kijko, Andrzej; Midzi, V. (Geological Society of South Africa, 2015-12)Southern Africa is considered a stable continental region in spite of several reported medium size earthquakes, some of which caused considerable damage and casualties. The 1969 Ceres 6.3 magnitude earthquake is considered ...
-
Hamdache, M.; Peláez, J.A.; Kijko, Andrzej; Smit, Ansie (Springer, 2017-04)We estimate the energetic and spatial characteristics of seismicity in the Algeria–Morocco region using a variety of seismic and statistical parameters, as a first step in a detailed investigation of regional seismic ...
-
Dyson, Liesl L.; Pienaar, Nita; Smit, Ansie; Kijko, Andrzej (Wiley, 2021-01)Understanding the character of hail is an important part of mitigating its impact on life and property. Climatologies of hail over South Africa are rare and based on observed data with a coarse spatial and temporal resolution. ...

Kowsari, Milad; Ghazi, Hamed; Kijko, Andrzej; Javadi, Hamid Reza; Shabani, Elham (Springer, 2021-06)The Iranian Plateau has been subjected to destructive earthquakes throughout its history. Reliable assessment of the seismic hazard in this earthquake-prone region is therefore essential. Our study focuses on estimating ...

Beirlant, Jan; Kijko, Andrzej; Reynkens, Tom; Einmahl, John H.J. (Springer, 2018-01)The area-characteristic, maximum possible earthquake magnitude TM is required by the earthquake engineering community, disaster management agencies and the insurance industry. The Gutenberg–Richter law predicts that ...
-
Kijko, Andrzej; Smit, Ansie (Seismological Society of America, 2016-06)Most probabilistic seismic-hazard analysis procedures require that at least three seismic source parameters be known, namely the mean seismic activity rate λ, the Gutenberg–Richter b-value, and the area-characteristic ...

Kijko, Andrzej; Vermeulen, Petrus Johannes; Smit, Ansie (Springer, 2022-04)Please read the abstract in the article.
-
Kijko, Andrzej; Smit, Ansie (Seismological Society of America, 2012-06)The Aki (1965) maximum likelihood estimate of the Gutenberg–Richter b-value is extended for use in the case of multiple catalogs with different levels of completeness. The most striking feature of this newly derived ...
-
Singh, Mayshree; Kijko, Andrzej (Springer, 2011-10)A first-order seismotectonic model was created for South Africa. This was done using four logical steps: geoscientific data collection, characterisation, assimilation and zonation. Through the definition of subunits of ...
-
Liebenberg, Keagan; Smit, Ansie; Coetzee, Serena Martha; Kijko, Andrzej (Springer, 2017-08)The majority of seismic activity in South Africa is related to extensive mining operations, usually in close proximity to densely populated areas where a relatively weak seismic event could cause damage. Despite a significant ...
-
Karimiparidari, Sepideh; Zaré, Mehdi; Memarian, Hossein; Kijko, Andrzej (Springer, 2013-07)A uniform earthquake catalog is an essential tool in any seismic hazard analysis. In this study, an earthquake catalog of Iran and adjacent areas was compiled, using international and national databanks. The following ...

Mapuranga, Victor Philip; Kijko, Andrzej; Saunders, I.; Singh, A.; Singh, M.; Zulu, S. (Geological Society of South Africa, 2022-03)On the 6th of February 2016 at 11:00 hours local time (0900 UTC), KwaZulu-Natal was struck by an earthquake of local magnitude ML=3.8. The epicentre of the earthquake was located offshore in the Durban Basin. The ...

Esterhuyse, Surina; Avenant, Marinda; Redelinghuys, Nola; Kijko, Andrzej; Glazewski, Jan; Plit, Lisa; Kemp, Marthie; Smit, Ansie; Vos, A. Tascha (Elsevier, 2018-07)Biophysical and socio-economic monitoring during unconventional oil and gas (UOG) extraction is important to assess change and to have reference conditions against which to identify UOG extraction activity impacts. The ...
-
Heidarzadeh, Mohammad; Kijko, Andrzej (Springer, 2011-01)Due to lack of sufficient historical data of tsunami in the Makran subduction zone (MSZ) at the northwestern Indian Ocean, a probabilistic method is employed to assess the tsunami hazards in this region. The method employs ...
-
Smit, Ansie; Kijko, Andrzej; Stein, Alfred (Springer, 2017-08)The paper presents a new method for empirical assessment of tsunami recurrence parameters, namely the mean tsunami activity rate λT, the Soloviev–Imamura frequency–magnitude power law bT-value, and the coastline-characteristic, ...
-
Triantafyllou, Ι.; Papadopoulos, G.A.; Kijko, Andrzej (Springer, 2023-03)Tsunami risk is considered as the probability of a particular coastline being struck by a tsunami that may cause a certain level of impact (destructiveness). The impact metric of a tsunami is expressed in terms of tsunami ...
