A major volcanic eruption poses a threat to the environment, food security, public health, and the socio-economic stability of a region. Although the frequency of a supereruption is difficult to calculate due to information bias and the number of unidentified supervolcanoes, it has been concluded that the probability of such an event occurring is approximately 1 in every 6 centuries. These findings indicate that humanity could face the impacts of a supereruption in the near future, especially given the lack of global efforts to mitigate its effects. Exploring supervolcanoes is useful for understanding their functioning and evolution over geological time. The proposed outreach article aims to address this need by mapping the major global supervolcanic eruptions that have marked Earth’s geological history, highlighting their short- and long-term impacts and consequences. The purpose is to raise awareness among decision-makers and the community about the importance of preparing for extreme scenarios and strengthening regional resilience to large-scale natural events.
