| Abstract | Large collapse calderas represent an extremely explosive type of volcanism with potential for global impact. Although very rare, such super-eruptions represent a serious threat to to mankind. However, moderate to small eruptions from such calderas represent a major risk as well, particularly in urban as well, particularly in urban, particularly in urban areas. Oneexampleisthe1994eruptionoftheRabaulcalderaOneexampleisthe1994eruptionoftheRabaulcalderaneexampleisthe1994eruptionoftheRabaulcaldera example is the 1994eruptionoftheRabaulcaldera1994 eruptionoftheRabaulcalderaeruption of the Rabaul caldera which destroyed the town of Rabaul (Papua New Guinea). This event demonstrated that eruptions are possible with demonstrated that eruptions are possible withare possible with with only minor and very short-term precursory signals, while while long episodes of unrest involving uplifts on the order of up toon the order of up ton the order of up to 1 meter and intense seismicity may occur without immediate volcanic activity.
