We hope you have been celebrating International Women's Day wherever you are today. In honour of the day you can read about five women who have gone mostly unrecognised in their scientific contributions:

Kvinder har stort set altid lavet videnskab, men de har sjældent fået den anerkendelse, de har fortjent.

The Indonesian volcano Mount Ili Lewotolok is erupting:

Lewotolo is a stratovolcano located in the north-central part of the island of Lembata. After a relatively quiet 8 year period, with little to no seismic activity, Lewotolo renewed activity on Friday November 27th with a continuing phase of large ash emissions and small amount of gas and steam, creating a 500 m high ash column. Increased seismic activity was also observed. On Sunday, a major blast occurred sending an ash column over 15 km into the sky

Thousands have fled the scene of a rumbling Indonesian volcano that burst to life for the first time in several years, belching a massive column of smoke and ash, the disaster agency said Monday.

Scientists compiled the largest dataset of a specific type of seismograms and conducted big data analysis and numerical simulations to reveal an oceanic plateau in the Earth's lower mantle, 800 kilometers deep underneath Eastern Siberia. This discovery pushes Hawaii's birthplace back to 100 million years. Read more here:

An oceanic plateau has been observed for the first time in the Earth's lower mantle, 800 kilometers deep underneath Eastern Siberia, pushing Hawaii's birthplace back to 100 million years, says a Michigan State University geophysicist.

New research suggests when a volcano erupts matters!

Detailed modeling of the effect of volcanic eruptions on the El Niño Southern Oscillation (ENSO) has shown that the climate response to these events depends on the timing of the eruption and the preceding conditions. The research, led by KAUST researchers Evgeniya Predybaylo and Georgiy Stenchikov,...

New research published in Geology suggests that Earth's largest mass extinction at the end of the Permian was caused by volcanism.

Researchers in Japan, the US and China say they have found more concrete evidence of the volcanic cause of the largest mass extinction of life. Their research looked at two discrete eruption events: one that was previously unknown to researchers, and the other that resulted in large swaths of terres...

Some interesting news about measuring gas emissions from active volcanoes using modified long-range drones.

Specially-adapted drones developed by a UCL-led international team have been gathering data from never-before-explored volcanoes that will enable local communities to better forecast future eruptions.

As reports of stunning rescues from the devastating earthquake experienced by Turkey last Friday appear in our news feeds, let's take a moment to consider why so many earthquakes occur in Turkey.

The region has experienced 29 earthquakes with a magnitude of 6.0 or higher in the last 100 years
