The ice cores indicated a large sulfate spike, accompanied by tephra deposition,{{sfn|Narcisi|Petit|Delmonte|Batanova|2019|p=165}} around 1257<ref name="Auchmann2015"/> - 1259,{{sfn|Narcisi|Petit|Delmonte|Batanova|2019|p=165}} the largest{{efn|Sulfate spikes around 44 BC and 426 BC, discovered later, rival its size.<ref name="Sigl2015"/>}} in 7,000 years and twice the size of the spike due to the [[1815 eruption of Mount Tambora|1815 eruption of Tambora]].<ref name="Auchmann2015"/> In 2003, a dense rock equivalent volume of {{convert|200|-|800|km3}} was estimated for this eruption,{{sfn|Oppenheimer|2003|p=419}} but it was also proposed that the eruption might have been somewhat smaller and richer in sulfur.{{sfn|Oppenheimer|2003|p=420}} The volcano responsible was thought to be located in the [[Ring of Fire]]{{sfn|Campbell|2017|p=113}} but could not be identified at first;<ref name="Science2013"/> [[Tofua]] volcano in Tonga was proposed at first but dismissed, as the Tofua eruption was too small to generate the 1257 sulfate spikes.<ref name="Caulfield2011"/> A volcanic eruption in 1256 at [[Harrat Rahat|Harrat al-Rahat]] near [[Medina]] was also too small to trigger these events.{{sfn|Stothers|2000|p=361}} Other proposals included several simultaneous eruptions.{{sfn|Brovkin|Lorenz|Jungclaus|Raddatz|2010|p=675}} Estimated diameters and positions of the calderas left by the eruption ranged from {{convert|10|-|30|km}},{{sfn|Oppenheimer|2003|p=424}} close to the [[equator]] and probably north of it.{{sfn|Hammer|Clausen|Langway|1988|p=107}}
