No Redoubt: Volcanic eruption forecasting improved

Forecasting volcanic eruptions with success is heavily dependent on recognizing well-established patterns of pre-eruption unrest in the monitoring data. But in order to develop better monitoring procedures, it is also crucial to understand volcanic eruptions that deviate from these patterns. New research retrospectively documented and analyzed the period immediately preceding the 2009 eruption of the Redoubt volcano in Alaska, which was characterized by an abnormally long period of pre-eruption seismic activity that’s normally associated with short-term warnings of eruption.

Earth’s center is 1,000 degrees hotter than previously thought, synchrotron X-ray experiment shows

The temperature near Earth’s center is 6,000 degrees Celsius, 1,000 degrees more than given in an experiment 20 years ago. This experiment with synchrotron X-rays confirms geophysical models that explain Earth’s magnetic field and the creation and intense activity of hot-spot volcanoes. The scientists also established why the earlier experiment had produced lower temperature figures.
