    en.wikipedia.org/wiki/Prediction_of_volcanic...

    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.

    Evidence suggests that the anomaly was predominantly a volcanic winter event caused by the massive 1815 eruption of Mount Tambora in April in modern-day Indonesia (commonly referred to as the Dutch East Indies at the time). This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536 ...

  9. Dense-rock equivalent - Wikipedia

    en.wikipedia.org/wiki/Dense-rock_equivalent

    Dense-rock equivalent (DRE) is a volcanologic calculation used to estimate volcanic eruption volume. One of the widely accepted measures of the size of a historic or prehistoric eruption is the volume of magma ejected as pumice and volcanic ash, known as tephra during an explosive phase of the eruption, or the volume of lava extruded during an effusive phase of a volcanic eruption.
