Η ακραία θερμοκρασία του μάγματος, η οποία κυμαίνεται από 500 μέχρι 1.170 °C προκαλεί σχεδόν ακαριαία εξάτμιση του νερού, η οποία οδηγεί σε μία έκρηξη <a href="/wiki/%CE%91%CF%84%CE%BC%CF%8C%CF%82" title="Ατμός">ατμού</a>, νερού, τέφρας, βράχων και <a href="/wiki/%CE%97%CF%86%CE%B1%CE%B9%CF%83%CF%84%CE%B5%CE%B9%CE%B1%CE%BA%CE%AE_%CE%B2%CF%8C%CE%BC%CE%B2%CE%B1" title="Ηφαιστειακή βόμβα">ηφαιστειακών βομβών</a>.<sup id="cite_ref-USGS_1-0" class="reference"><a href="#cite_note-USGS-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> Η παρουσία <a href="/wiki/%CE%9B%CE%AC%CE%B2%CE%B1" title="Λάβα">λάβας</a> είναι ασυνήθης. Αν περιλαμβάνει λιωμένο μάγμα, τότε η έκρηξη ονομάζεται φρεατομαγματική. Οι εκρήξεις αυτές δημιουργούν αβαθείς <a href="/wiki/%CE%97%CF%86%CE%B1%CE%B9%CF%83%CF%84%CE%B5%CE%B9%CE%B1%CE%BA%CF%8C%CF%82_%CE%BA%CF%81%CE%B1%CF%84%CE%AE%CF%81%CE%B1%CF%82" title="Ηφαιστειακός κρατήρας">κρατήρες</a> γνωστούς ως <a href="/wiki/%CE%9C%CE%AC%CE%B1%CF%81" title="Μάαρ">μάαρ</a>. </p><p>Συνήθως οι φρεατικές έχουν τοπικό μόνο αντίκτυπο, αλλά τα αναβλήμματα μπορούν να εκτοξευθούν χιλιόμετρα ψηλά στην ατμόσφαιρα και να επηρεάσουν τις αερομεταφορές.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> Παρόλα αυτά, οι φρεατικές εκρήξεις μπορούν να προκαλέσουν σημαντικό αριθμό θυμάτων, όπως για παράδειγμα το 2014 μια φρεατική έκρηξη στο <a href="/wiki/%CE%8C%CF%81%CE%BF%CF%82_%CE%9F%CE%BD%CF%84%CE%AC%CE%BA%CE%B5" title="Όρος Οντάκε">όρος Οντάκε</a> προκάλεσε το θάνατο 57 τουλάχιστον ατόμων.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">&#91;</span>3<span class="cite-bracket">&#93;</span></a></sup> Ένας άλλος κίνδυνος είναι έκλυση δηλητηριωδών αερίων. Το 1979 στην <a href="/wiki/%CE%99%CE%AC%CE%B2%CE%B1" title="Ιάβα">Ιάβα</a> μια μεσαίου μεγέθους φρεατική έκρηξη προκάλεσε το θάνατο 142 ατόμων, ο οποίος αποδόθηκε στην έκλυση αερίων με μεγάλη συγκέντρωση <a href="/wiki/%CE%94%CE%B9%CE%BF%CE%BE%CE%B5%CE%AF%CE%B4%CE%B9%CE%BF_%CF%84%CE%BF%CF%85_%CE%AC%CE%BD%CE%B8%CF%81%CE%B1%CE%BA%CE%B1" title="Διοξείδιο του άνθρακα">διοξειδίου του άνθρακα</a>.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">&#91;</span>4<span class="cite-bracket">&#93;</span></a></sup> </p><p>Σε αντίθεση με τις ηφαιστειακές εκρήξεις οι οποίες σχετίζονται με την κίνηση μεγάλων ποσοτήτων μάγματος, η πρόβλεψη των φρεατικών εκρήξεων είναι πιο δύσκολη. Οποιαδήποτε πρόδρομα χαρακτηριστικά σχετίζονται με τις φρεατικές εκρήξεις είναι πολύ τοπικά και βραχύβια.
