Assessing the threat to Western Australia from tsunami generated by earthquakes along the Sunda Arc

Burbidge, David; Cummins, Phil - In: Natural Hazards 43 (2007) 3, pp. 319-331

A suite of tsunami spaced evenly along the subduction zone to the south of Indonesia (the Sunda Arc) were numerically modelled in order to make a preliminary estimate of the level of threat faced by Western Australia from tsunami generated along the Arc. Offshore wave heights from these tsunami...

Increased frequency of flash floods in Dire Dawa, Ethiopia: Change in rainfall intensity or human impact?

Billi, Paolo; Alemu, Yonas; Ciampalini, Rossano - In: Natural Hazards 76 (2015) 2, pp. 1373-1394

In the first decade of the twenty-first century, Ethiopia has been subjected to an increased frequency of flash floods, especially in the town of Dire Dawa. The results of international organizations studies point to no evidence of a climate-driven change in the magnitude/frequency of floods,...

Regional Assessment of the Effects of Land-Use Change on Landslide Hazard By Means of Physically Based Modelling

Beek, L.P.H. Van; Asch, Th.W.J Van - In: Natural Hazards 31 (2004) 1, pp. 289-304

Physically based models are capable of evaluating the effects of environmental changes through adaptations in their parameters. For landslide hazard zonation, this gives them an edge over traditional, statistically based techniques that require large datasets and often lack the objectivity to...

Spatio-temporal dynamics in the flood exposure due to land use changes in the Alpine Lech Valley in Tyrol (Austria)

Cammerer, Holger; Thieken, Annegret; Verburg, Peter - In: Natural Hazards 68 (2013) 3, pp. 1243-1270

Flood risk is expected to increase in many regions of the world in the next decades with rising flood losses as a consequence. First and foremost, it can be attributed to the expansion of settlement and industrial areas into flood plains and the resulting accumulation of assets. For a...
