A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. [1] Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions , collect eruptive products including tephra (such as ash or pumice ), rock and lava samples.
Scientists monitoring an active volcano will often measure the tilt of the slope and track changes in the rate of swelling. An increased rate of swelling, especially if accompanied by an increase in sulfur dioxide emissions and harmonic tremors is a high probability sign of an impending event.
Volcanoes, he said, were formed where the rays of the sun pierced the earth. The volcanoes of southern Italy attracted naturalists ever since the Renaissance led to the rediscovery of Classical descriptions of them by wtiters like Lucretius and Strabo. Vesuvius, Stromboli and Vulcano provided an opportunity to study the nature of volcanic ...
Much has been written in recent times on climatic events, but it is the well-reasoned and engaging explanation offered by Prager that makes it a riveting read. Given the recent spurt in extreme weather events, scientists now consider this a whole new field of science which may be with or without the influence of climate change." [3]
The scientific community is abuzz following the first eruption of Mauna Loa—the world’s largest volcano, situated on the Island of Hawaii—since 1984. The eruption occurred just before ...
In 2013, a study which found that out of over 4,000 peer-reviewed papers on climate science published since 1990, 97% agree, explicitly or implicitly, that global warming is happening and is human-caused. [37] [38] Surveys of scientists' views on climate change – with a focus on human caused climate change – have been undertaken since the ...

While scientists knew of past climate change such as the ice ages, the concept of climate as changing only very gradually was useful for descriptive climatology. This started to change during the decades that followed, and while the history of climate change science started earlier, climate change only became one of the main topics of study for ...
