  • Acting on disaster warnings: Don`t miss the human factor

    We need to understand why some people act on early warnings while others ignore them, says disaster preparedness specialist Sudhir Kumar. The Great East Japan Earthquake and subsequent tsunami of 11 March 2011 challenged global ideas about responding to disasters. It showed that structural defences alone, such as breakwaters, coastal dykes and tidal barriers, cannot provide protection ...

  • Using disaster warning tools to their best potential

    Stronger links between scientific tools and the environment in which they operate can improve the effectiveness of early warning. To say there is a lot riding on disaster management is an understatement. The lives and livelihoods lost, as well as extensive damage, underscore the human, ...

  • Emergency logistics and risk mitigation in Thailand following the Asian tsunami

    A series of recent natural disasters (earthquakes, floods, droughts) and man-made crises (civil unrest, war, political disturbance) have highlighted the vulnerability of communities to unstable conditions. Reaching displaced people in crisis conditions is heavily dependent on the effectiveness of the supply chain and its management systems. Disaster responses have been modelled into, for example, ...

  • Why disaster warning and development go hand in hand

    To engage people in early action we must understand their experience, behaviour and constraints, says disaster policy expert Andrew Collins. Disaster predictions have significant uncertainty that tends to undermine efforts to act on early warnings. In Bangladesh, for example, where there ...

  • Decision support system for predicting tsunami characteristics along coastline areas based on database modelling development

    Tsunamis are extraordinary occurrences that are difficult to identify; most of the incidents have no recorded predictions and tsunamis are generally infrequent events with poor data acquisition. The development of a tsunami database system has become important for improving the management of information with regard to a tsunami early warning system for vulnerable communities along coastline ...

  • Time to stop losing ocean data to vandalism

    More must be done to prevent damage of ocean data buoys that costs money, vital data — and lives, say Sidney Thurston and M. Ravichandran. The global community relies on a rapidly expanding ocean observing network to understand the climate and ecosystems, to help warn against ocean-borne hazards such as tsunamis and storm surges caused by cyclones, and to support sea rescue ...

  • Climate Change Driving Weather off the Charts

    Meteorologists are calling the typhoon that slammed into the Philippines with 195-mile-an-hour winds on November 8, 2013, the most powerful tropical storm to make landfall on record. Super Typhoon Haiyan had gusts reaching 235 miles per hour and a storm surge swelling as high as 20 feet, so the destruction it left behind matched that of a tornado combined with a tsunami. Three days later, at the ...

  • A warming world means more destructive storms

    Elevated global temperatures bring a number of threats, including rising seas and more crop-withering heat waves. Higher surface water temperatures in the tropical oceans also provide more energy to drive tropical storm systems, leading to more-destructive hurricanes and typhoons. The combination of rising seas, more powerful storms, and stronger storm surges can be devastating. Just how ...
