I must have been busy last February. That is the only possible explanation for why I neglected to blog about an article Nalaka Gunawardene and I wrote, reflecting on the experience of providing effective disaster warnings, nine years after the 2004 Indian Ocean tsunami. The proliferation of information and communication technologies (ICTs) adds a new dimension to disaster warnings. Having many information sources, dissemination channels and access devices is certainly better than few or none. However, the resulting cacophony makes it difficult to achieve a coherent and coordinated response.
