An article in Ars Technica reports on an investigation of the area and ages of volcanic calderas and the duration of volcanic eruptions between 1900 and 2009 in relation to Benford’s Law.
Apparently Benford’s laws fit the eruption duration data “very well” and caldera areas offer “pretty good” fit, though the latter indicated that “some excessive rounding may have taken place”. The caldera eruption ages showed a marked deviation.
