A gripping investigation on a worldwide level. For over thirty years, scientists from all continents have been searching, in vain, for a mysterious volcano that triggered the most momentous explosive eruption of the last 10,000 years, twice as powerful as the eruption of the Tambora. The researchers know that it took place in the Middle Ages, in the 13th century, to be precise, and that it must have disrupted the climate on the entire planet. Yet, no traces have been found of the volcano, nor of the impacts and repercussions such an event traditionally has on nature and human societies. It's a total mystery! So much so that international scientists and historians have decided to unravel it by leading a large-scale probe. Presented like a thriller movie, this film closely follows the course of their investigation, traveling across the planet in search of clues, cross-checking their theories, until they undertake a far-off expedition and discover an ideal suspect. A monster volcano. Nevertheless, the researchers must still prove that it is indeed the mysterious volcano of the Middle Ages.

Nice twofer. I won't even complain about the supervolcano hyperbole.

Have they considered it happened on an atoll or island in the ocean and then subsided afterwards? Maybe look for a seamount with the top blown off and its summit hundreds or thousands of feet below the surface of the ocean…?

Or maybe it happened in Anarctica and centuries of wind-blown ice and snow have covered up the traces?

Yes, I remember donating to "Volcano Relief" back then to impress a chick.

If it was during human history, it would have been documented. I suspect it might have been in human pre-history.

I’d bet it’s in Indonesia, or maybe near Rabaul in New Guinea where they have a cluster of them now.

Maybe it was under water and is still there somewhere.

The under water possibility is great due to so many faults at the Pacific margins.

But why not Antarctica? There it would not take long for ice to completely bury its remains.

The reason given for an equatorial source/search was that the ice cores in Antarctica showed the same signature as those from Greenland.

I see. There would be more material in an Antarctic ice core sample than an Arctic sample for the same time reference if that’s where it occurred.

Did you hear of this one in Peru, 1600, cooled the climate severely, would slide in between Tambora and Krakatoa according to Wikipedia article:

The 1600 eruption had a Volcanic Explosivity Index of 6 and is considered to be the only major explosive eruption of the Andes in historical time.[144][145] It is the largest volcanic eruption throughout South America in historical time,[q] as well as one of the largest in the last millennium and the largest historical eruption in the Western Hemisphere.[148][149] It was larger than the 1883 eruption of Krakatoa in Indonesia and the 1991 eruption of Pinatubo in the Philippines.[150] Huaynaputina’s eruption column was high enough to penetrate the tropopause and influence the climate of Earth.[151][152]

The total volume of volcanic rocks erupted by Huayanaputina was about 30 km3 (7.2 cu mi)

Wikipedia has two separate lists for biggest volcanic eruption:

and

https://en.wikipedia.org/wiki/Supervolcano#Massive_explosive_eruptions

The biggest North American one seems to be:
