Prediction of volcanic activity, and volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities.
Unlike other volcanoes around the world that can go centuries between eruptions, this one can be measured in years. The most recent eruptions occurred in 1998, 2011 and 2015.
These are the volcanoes monitored by the California Volcano Observatory, in order of highest to lowest risk assessment. Mt Shasta. According to USGS risk assessment of the volcanoes in CalVO's region, the following volcanoes were ranked "very high threat potential". [4] Mount Shasta in far-northern California, north of Redding
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.
The Long Valley Caldera, which includes Mammoth Lakes area, has been having seismic activity, which can precede a volcanic eruption. Scientists say not to worry. One of California's riskiest ...
[73] Similarly, the California Volcano Observatory lists its threat level as "Very High." [4] [82] At the time of the early 20th century eruptions, the area surrounding the volcano was only sparsely populated, but a similar eruption today would threaten many lives and the northern Californian economy. [83]
The volcano was dormant for about half of last century, but rumbled back to life with a series of relatively small eruptions beginning in the 1990s. The government ordered evacuations then, and ...
We're able to do a much better job of monitoring the changes that occur at volcanoes as they wake up, but we are still quite a long ways from being able to forecast the time, the magnitude and the character of an eruption. Since the disaster, research has improved scientists' ability to predict volcanic eruptions. Still, there is not a definite ...
