Collapsed natural arch of Punta Ventana, Guayanilla, Puerto Rico
Collapsed natural arch of Punta Ventana, Guayanilla, Puerto RicoThe starting view is from January, 1970, a field photo of Punta Ventana (“Window Point”) at Guayanilla, Puerto Rico (Monroe, 1980). The image fades to the March 5, 2020 color photo of the same location (ten Brink, 2020). The natural arch had collapsed from earthquake shaking on January 6, 2020 during the 2020 Southwest Puerto Rico Earthquake Sequence.

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
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.
