Initial Phase Crisis Communications Following High Perceived Risk Events: The Volcanic Ash Crisis and the Japanese Tsunami as Examples

On 14 April 2010 the Icelandic volcano, Eyjafjallajökull, erupted resulting in a volcanic ash cloud across European airspace. The ash cloud caused a moratorium on flying and concerns over health effects to vulnerable populations. Not even a year since the volcanic ash cloud; on 11 March 2011 a massive 9.0-magnitude earthquake occurred near the northeastern coast of Japan, creating extremely destructive tsunami waves which hit Japan just minutes after the earthquake, triggering evacuations and warnings across the Pacific Ocean. The disaster also led to concerns over nuclear power plant meltdowns in the affected areas and risk of radiation. High perceived risks associated with the Japanese tsunami and volcanic ash crisis are examples of scenarios where accurate and timely health and safety communications are vital for effective emergency response. However, communications immediately following such events face unique challenges. This report describes the challenges faced in terms of crisis communication immediately following high perceived risk events and positions the example case studies in the context of an existing crisis communication paradigm.
