Volcanic crystals as time capsules of eruption history
Crystals formed prior to a volcanic event can provide evidence of processes leading to and timing of eruptions. Clinopyroxene is common in basaltic to intermediate volcanoes, however, its ability as a recorder of pre-eruptive histories has remained ...

The ectopic eruption of the maxillary first permanent molar (EEM) is a local alteration of dental eruption with a multifactorial aetiology. The aims of our study were to determine the prevalence of the EEM in children and to analyse whether there is a ...

Mapping eruption affected area using Sentinel-2A imagery and machine learning techniques
Volcanic eruptions are natural disasters with significant environmental and societal impacts. Timely detection and monitoring of volcanic eruptions are crucial for effective hazard assessment, mitigation strategies, and emergency response planning ...

The radiative forcing caused by a volcanic eruption is dependent on several eruption source parameters such as the mass of sulfur dioxide (SO2) emitted, the eruption column height, and the eruption latitude.

Johann Kiessling (1839-1905) und die Erforschung atmosphärisch-optischer Erscheinungen
Die vorliegende Abhandlung will an Johann Kiessling erinnern, der sich mit den so viel Aufsehen erregenden Dämmerungen nach dem Krakatau-Ausbruch (1883) eingehend befaßte und nach deren physikalischer Erklärung suchte.

The largest deep-ocean silicic volcanic eruption of the past century
A submersible study of the products of a large submarine eruption demonstrates the influence of the ocean on eruption dynamics. The 2012 submarine eruption of Havre volcano in the Kermadec arc, New Zealand, is the largest deep-ocean eruption in history ...

Role of eruption season in reconciling model and proxy responses to tropical volcanism
Significance The starting month of many historical tropical volcanic eruptions is unknown and often assumed constant in long model simulations. Here we use model simulations to show that the season of eruptions strongly affects both atmospheric ...

Deciduous teeth play an important role in the proper alignment, spacing and occlusion of permanent teeth. The calcification of deciduous teeth begins during the fourth prenatal month, and calcification of all deciduous teeth begin by the end of the sixth

After six years of quietness La Fournaise volcano entered into activity on March 9, 1998. Fissures opened gradually downwards on the northern flank of the cone. Two cones, Kapor and Krafft built, from which lava poured until September 1998. Several other
