Correlation Analysis for Total Electron Content Anomalies on 11th March, 2011

1. Introduction
Ionosphere is a shell of a large amount of electrons and it is disturbed by various causes such as volcanic eruptions [Heki, 2006;Dautermann et al., 2009], solar flares [Donnelly, 1976], earthquakes [ Cahyadi and Heki, 2015], and so on. Analyzing Total Electron Content (TEC) data is one of the most popular method to monitor the ionosphere. TEC data contains the number of electrons integrated along the line of sight between the GNSS satellites and the observation stations on the ground. Japan has a dense GNSS observation network (the GNSS earth observation network, GEONET) to collect daily TEC.

Sulfur, Magma, and the Velocity of Bubbles in Volcanic Eruptions

Gaseous flow of sulfur in a crystal-poor magma under the surface is an interesting study in the field of volcanism. Scientists are using computer simulations and mathematical constructs to test why some volcanoes erupt more violently and gaseously than others.

Bubbles lead to disaster

Why are volcanologists interested in vapour bubbles? Because they can accumulate in a magma reservoir underneath a volcano, priming it to explode. Researchers at ETH Zurich and Georgia Institute of Technology have now discovered how bubbles are able to accumulate in the magma.
