Plinian

It would be impossible in any case for me to attempt a Plinian panegyric, or a French éloge.

Read two papers before the Plinian Society of Edinburgh "at the close of 1826 or early in 1827."

Fast-moving deadly pyroclastic flows (“nuées ardentes”) are also commonly associated with plinian eruptions.

The most powerful eruptions are called “plinian” and involve the explosive ejection of relatively viscous lava.
