Characterisation of the Quaternary eruption record: analysis of the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database

Table 5 The median age, T₅₀, of eruptions in each magnitude band

Magnitude	Median time (T₅₀)
50% of time covered by LaMEVE database	1.25 Ma
M ≥ 4 (entire database)	20,455
M ≥ 5	53,000
M ≥ 6	107,750
M ≥ 7	443,000
M ≥ 8	935,000

The time, T₅₀, by which 50% of eruptions of each magnitude interval have occurred. For example, 50% of recorded M≥4 eruptions are recorded in the last 20,455 years (in a database spanning 2.5 Myr).
