The magnitude and impact of the Youngest Toba Tuff super-eruption

open access: yesFrontiers in Earth Science, 2014
Super-eruptions, orders of magnitude larger than eruptions experienced in historic times, have devastated wide areas by pyroclastic flows, covered continent-size areas by ash fallout, and injected large quantities of aerosols into the stratosphere ...

On the fate of pumice rafts formed during the 2012 Havre submarine eruption

open access: yesNature Communications, 2014
Pumice rafts are floating mobile accumulations of low-density pumice clasts generated by silicic volcanic eruptions. Pumice in rafts can drift for years, become waterlogged and sink, or become stranded on shorelines.

Mesial Migration of Lower Molars in Relation to Facial Growth and Eruption

open access: yesAustralasian Orthodontic Journal, 1996
Mesial migration of teeth in the huccal segments is a well recognised phenomenon in the human dentition. Its aetiology is not fully understood. It has heen suggested that it is, to some extent, dependent on growth changes in the lower face.

Eruptive syringoma

open access: yesDermatology Online Journal, 2003
Eruptive syringoma is a rare eruption of small, flesh-colored papules that occurs in successive crops on the anterior body surfaces and arises in the peripubertal period. The lesions are benign, and treatment options are generally unsatisfactory. The case of a 27-year-old man with a 1-year history of eruptive syringoma is presented.

Ash from Changbaishan Millennium eruption recorded in Greenland ice: Implications for determining the eruption's timing and impact

open access: yes, 2014
Major volcanic eruptions can impact on global climate by injecting large quantities of aerosols and ash into the atmosphere that alter the radiative balance and chemical equilibrium of the stratosphere.
