Institutional framework and administrative systems for effective disaster risk governance – Perspectives of 2013 Cyclone Phailin in India

Abstract: Risk Governance mechanism is guided by the administrative systems and institutional framework of the central and provincial governments. Policies and legislations related to the risk management are paramount towards defining the efficiency of the on-ground implementation of the Disaster Management Plan. The present study will analyse the efficacy of robust national level institutional system on India in the form of Disaster Management Act 2005 along with a wide range of National Level Institutions related to early warning, meteorology, remote sensing, information and communication technology, satellite technology, disaster response management, which have substantially contributed to high level of preparedness, in term of effective response to disaster in the light of a category 5 tropical cyclone Phailin, which struck the east coast of India in October 2013. The study principally examines the effectiveness of the Indian policy pertaining to the disaster management in achieving its intended outcome, i.e. achieving effective mitigation and response to a disaster thereby minimising the casualties and losses to the community caused by the cyclone Phailin, India in 2013. It is also analysed how the implementation of the policy enabled the government of the Indian state of Odisha to minimize the casualties and damage to property, in stark contrast to the 1999 Super Cyclone in the same state of India where over 10,000 people died. This was a remarkable achievement considering the havoc anarchy among administration in the year 1999, when Odisha was challenged by the similar intensity cyclone.

Application of geospatial technologies for multi-hazard mapping and characterization of associated risk at local scale

Abstract: In this study multi-hazard risk assessment is carried out in Arithang ward, one of the major wards within Gangtok Municipal Corporation, with the objectives of (a) landslide and earthquake hazard mapping of Gangtok city with analytical hierarchy process (b) vulnerability mapping in Arithang ward and (c) semiquantitative and semiqualitative risk analysis. Landslide hazard zonation (LHZ) depicts that very high and high hazard zone occupies 6% and 17% of the Gangtok city whereas 60% and 18% of area falls under medium and low hazard category respectively. With respect to seismic hazard susceptibility 13% and 22% of area falls under very high and high category respectively. Semiquantitative risk analysis reveals that majority of the residential buildings are concentrated in low earthquake and landslide hazard zone followed by 39% and 35% within medium class. Only 0.6% and 7% of residential buildings are found in high earthquake and landslide hazard zones. Bamboo and wood made buildings are found to clu...

Role of crustal heterogeneity beneath Andaman–Nicobar Islands and its implications for coastal hazard

Abstract: The Andaman–Nicobar (A–N) Islands region has attracted many geo-scientists because of its unique location and complex geotectonic settings. The recent occurrence of tsunamis due to the megathrust tsunamigenic north Sumatra earthquake (Mw 9.3) with a series of aftershocks in the A–N region caused severe damage to the coastal regions of India and Indonesia. Several pieces of evidence suggest that the occurrence of earthquakes in the A–N region is related to its complex geodynamical processes. In this study, it has been inferred that deep-seated structural heterogeneities related to dehydration of the subducting Indian plate beneath the Island could have induced the process of brittle failure through crustal weakening to contribute immensely to the coastal hazard in the region. The present study based on 3-D P-wave tomography of the entire rupture zone of the A–N region using the aftershocks of the 2004 Sumatra–Andaman earthquake (Mw 9.3) clearly demonstrates the role of crustal heterogeneity in seismogenesis and in causing the strong shakings and tsunamis. The nature and extent of the imaged crustal heterogeneity beneath the A–N region may have facilitated the degree of damage and extent of coastal hazards in the region. The 3-D velocity heterogeneities reflect asperities that manifest what type of seismogenic layers exist beneath the region to dictate the size of earthquakes and thereby they help to assess the extent of earthquake vulnerability in the coastal regions. The inference of this study may be used as one of the potential inputs for assessment of seismic vulnerability to the region, which may be considered for evolving earthquake hazard mitigation model for the coastal areas of the Andaman–Nicobar Islands region.
