Controls on post-fire debris flows in Oregon
Wildfire often amplifies the likelihood and magnitude of debris flows in steep terrain. In arid climates (e.g. US Mountain West and Southwest), post-fire debris flows typically occur during the first rains following fire, suggesting that rainfall-driven erosion is a strong control on in-channel preconditioning and triggering of these hazards.

5 Geomagnetic Storms that Reshaped Society (AD)
Every 11 years the Sun's magnetic field flips. This period is referred to as a solar cycle. As we approach the peak of Solar Cycle 25, activity on the Sun’s surface will increase, including more solar flares, sunspots, and coronal mass ejections.
