Gli avvisi del Volcano Observatory for Aviation (VONA) sono messaggi in lingua inglese brevi e concisi, rivolti a chi deve organizzare spostamenti di veicoli in caso di emergenza, a piloti e a gestori del traffico aereo al fine di fornirgli informazioni sulle attività eruttive dei vulcani che potrebbero generare pericolose nubi di cenere.
Di Seguito è riportato l'elenco delle Esercitazioni effettuate.
