The 18 August flow was more than 18 m (55 feet) thick and still warm almost a year after congealing.
Explosions of ash completed this long eruptive period. Cannon-like, highly explosive eruptions in January and March 1974 threw out large quantities of ash as a column into the atmosphere, and as avalanches flowing down the cone’s sides.
However, the most violent explosions occurred on 19 February 1975, accompanied by what eye-witnesses described as atmospheric shock waves.However, it is well-known that if a radiometric ‘date’ contradicts a fossil-derived (evolutionary) age, the date is discarded as erroneous. See Lubenow, M., The pigs took it all, 6,000 years of earth history. 9), the K-Ar method cannot be used to date samples that are much younger than 6,000 years old (Dalrymple, 1991, p. 93)Cambridge, Massachusetts, USA, performed the K-Ar dating for Austin et al. However, when they did, their website clearly stated in a footnote that their equipment could not accurately date rocks that are younger than about 2 million years old ("We cannot analyze samples expected to be younger than 2 M.
