The magnitude of Mount Shasta's 1786 eruption is not well-defined, but it is considered to be a relatively minor eruption in terms of its scale and impact compared to larger volcanic events. It likely produced a moderate amount of volcanic ash and lava flows in the immediate vicinity of the volcano.

1815 eruption of Mount Tambora
Mount Shasta's last known eruption occurred around 1786, based on geological records. Since then, the volcano has been classified as dormant, with no recent signs of volcanic activity.
May 18, 1980
The biggest eruption of Mount Shishaldin occurred around 200 CE and resulted in the formation of a large caldera at the summit of the volcano. This eruption was one of the most explosive events in its history and had significant impacts on the surrounding area.
The first eruption scientists think, was in 1808. Then, there was another in 1821 and again one in 1843. The eruption of 1963 is the biggest and most destructive recorded eruption for Mount Agung.
No. Compared with other volcanoes of the same type, Mount St. Helens is not extraordinarily large and is smaller than it was prior to its 1980 eruption. The 1980 eruption was large, but nowhere near the largest.
No, because Mount Tambora did erupt in 2011. It was however the largest eruption in recorded history.
