The purpose of World Tsunami Awareness Day (WTAD) is to raise awareness about reducing tsunami-related risks and enhance community preparedness. In 2023, the theme of WTAD will mirror the theme of the International Day of Disaster Reduction: ‘fighting inequality for a resilient future‘. Activities will explore the reciprocal relationship between tsunamis and inequality: how inequality makes tsunamis more dangerous for certain populations and how the aftermath of a tsunami can drive vulnerable people further into poverty and exacerbate inequality. WTAD 2023 activities will focus on raising awareness about the underlying disaster risk drivers – poverty, inequality and vulnerability – that make tsunamis more deadly for those most at risk.
