In many valleys, the thickness of ignimbrite may be 70–80 m.

The Changbaishan ignimbrite has a low aspect ratio of 1.87 × 10, respectively.

High-precision chronologies are needed for studies of rapid climate changes.

The Dutch records show that following the Lateglacial/Holocene climate warming, birch woodlands expanded between 11,530 and 11,500 cal BP during the Friesland Phase of the Preboreal.

We also look at 3 case studies: one a piece of wood which has been independently dendrochronologically dated, and two others of unknown age relating to archaeological activity at Silchester, UK (Roman) and Miletos, Anatolia (relating to the volcanic eruption at Thera).

The method has both advantages and limitations vis-a-vis the calibration of individual dates.

The ignimbrite-forming eruption may have lasted one and a half to four days (35–104 hours), while the Plinian eruption may have lasted three to nine and a half days (77–230 hours).

The total duration of the eruption may have been four and a half to fourteen days (111–333 hours).

The 946 eruption of Paektu Mountain, also known as the Millennium eruption or Tianchi eruption, was one of the most powerful in recorded history and is classified as a VEI 7 event. Since longer dated tree-ring sequence, finer sample resolution, and higher 14C analytical precision all facilitate more and tighter tie-points for better WM dating. 947 ± 3, where overall and combined agreement indices of the models reach their highest values.
