This document is the seventh in a series of hazard-specific risk assessment modules, compiled as part of the Words into Action Guidelines on National Disaster Risk Assessment by UNISDR. This section provides a general introduction to the assessment of coastal erosion hazard and risk. Coastal erosion (or shoreline retreat) is the loss of coastal lands du…
This paper provides a timely review of progress and ongoing research needs in tsunami hazard and risk science since the most recent major event, the Tohoku tsunami in 2011. The tsunami community has made significant progress in understanding tsunami hazard from seismic sources. However, this is only part of the inputs needed to effectively manage tsunam…
The goal of this paper is to examine how government continuity planning contributes to strengthening the public sector’s disaster preparedness, resulting in enhanced resilience of the public sector. The paper analyzes basic principles of government continuity planning using Complex Adaptive Systems (CAS) theory while summarizing recent developments in t…
On 11 March 2011, the Great East Japan Earthquake and Tsunami severely damaged the Fukushima Daiichi Nuclear Power Plant (FDNPP). Large radioactivity released induced multi-hazard disasters on human livelihoods and ecosystems in the Fukushima Prefecture. In December 2018, some 43,000 residents of Fukushima were yet to return to their hometowns, with…
The demonstrated early warning capability of Global Navigation Satellite Systems (GNSS) to accurately, rapidly, and cost effectively measure deformation of the Earth’s surface and the response of the ionosphere to this deformation was the factual basis for the GNSS Tsunami Early Warning Systems Workshop (GTEWS) and this report. GTEWS 2017 was held in Se…
