Ever since NASA confirmed the presence of water on the moon, a number of researches have been conducted to understand the source of water on the surface. And, now, a new research has suggested a very unlikely source for this water. It stated that the presence of water on the Earth's closest neighbour could be a result of volcanoes – which we now know occurred a number of times on the moon in the past.The volcanic activity of the moon could have started as early as 4.2 billion years ago. It likely lasted until about 1…

Some 252 million years ago the world was going through a tumultuous period of rapid global warming.To understand what caused it, scientists have looked to one particular event in which a volcanic eruption in what is now Siberia spewed huge volumes of greenhouse gas into the atmosphere.  However, there is evidence the climate was already changing before this.Sea surface temperatures had increased by more than 6-8 ℃ in the hundreds of thousands of years leading up to the Siberian outpouring. Temperatures increased again…

While the emergency response is celebrated, the event has sparked questions about how much advance warning is possible for this type of natural disaster. …

(a) Transcrustal magmatic systems associated with porphyry copper deposits. (b) Transcrustal magmatic systems associated with large eruptions. The sketch highlights the similarities between the two systems and is inspired from sketches of previous works. The ~40 km depth is indicative and used for consistency with the model which is run for a maximum pressure of 1.2 GPa. Credit: Communications Earth & Environment (2022). DOI:…
