Una erupción pliniana es un tipo de erupción volcánica caracterizada por su similitud con la acontecida en el monte Vesubio en el año 79 d. C., según fuera descrita por Plinio el Joven en una carta dirigida a Cornelio Tácito.
In the criteria of Volcanic Explosivity Index, recognizing an eruption as ultra-Plinian would make it at least VEI-5 or higher. The threshold for ultra-Plinian eruptions is defined by an eruptive column height of 45 km (28 mi), or 41 km (25 mi) more recently.
The stronger eruptive types are Pelean eruptions, followed by Plinian eruptions; the strongest eruptions are called Ultra-Plinian. Subglacial and phreatic eruptions are defined by their eruptive mechanism, and vary in strength.
Erupciones Plinianas - Volcanes. Las más grandes y violentas de todos los tipos de erupciones volcánicas son las llamadas erupciones plinianas. Son causadas por la fragmentación del magma con gases, y por lo general se asocian con magmas muy viscosos (dacita y riolita).
The Tierra Blanca Joven eruption is El Salvador's largest volcanic eruption in the last 10,000 years. This VEI-6 Plinian eruption occurred during the 5th century and was larger than the 1883 eruption of Krakatoa or the 1991 eruption of Mount Pinatubo, having probably been more comparable to the 1815 eruption of Mount Tambora.

14 de abr. de 2023 · Ultra-Plinian eruptions are the largest of all volcanic eruptions, and are so voluminous that large calderas form above vacated magma chambers. These eruptions are more intense and have a higher eruption rate than Plinian ones and form higher eruption columns.
