New era of violent and unpredictable eruptions at Stromboli volcano, Italy

New era of violent and unpredictable eruptions at Stromboli volcano, Italy

New research published in Nature Communications suggests the internal ‘plumbing’ system of the Stromboli volcano in Italy may have changed, allowing magma from deep beneath the surface to rise more easily, triggering violent and unpredictable blasts. The research follows a series of surprisingly strong eruptions and paroxysms in 2019.

The fullest investigation of the massive Hunga Tonga-Hunga Ha’apai eruption to date

The fullest investigation of the massive Hunga Tonga-Hunga Ha’apai eruption to date

In January 2022, Hunga-Tonga Hunga-Ha’apai (HT-HH) emitted the biggest atmospheric explosion recorded on Earth in more than 100 years. Several months after the eruption, a New Zealand-led team has completed the fullest investigation to date into the eruption of this underwater Tongan volcano.

Study shows how Earth-Sun distance dramatically influences annual weather cycles in the equatorial Pacific in a 22 000-year cycle

Study shows how Earth-Sun distance dramatically influences annual weather cycles in the equatorial Pacific in a 22 000-year cycle

A new research led by the University of California, Berkeley, demonstrates that one driver of annual weather cycles in the eastern equatorial Pacific Ocean—in particular, a cold tongue of surface waters stretching westward along the equator from the coast of South America—has gone unrecognized: the changing distance between Earth and the Sun.

Predicting earthquakes using ionospheric total electron content anomalies- study

Predicting earthquakes using ionospheric total electron content anomalies- study

A new study published recently in Remote Sensing proposes the implementation of machine learning support vector machine (SVM) technique, applied with GPS ionospheric total electron content (TEC) pre-processed time series estimations, to evaluate potential precursors caused by earthquakes.

How solar storms affect railway signals

How solar storms affect railway signals

A project investigating the effect of solar storms on railway signals, presented this week at the National Astronomy Meeting (NAM 2022) by Cameron Patterson, a PhD student at Lancaster University, shows how fluctuations in space weather are disrupting train signals and causing significant delays.
