Solar flares are explosions of energetic radiation that can have potentially devastating effects on our communication systems, causing radio blackouts and affecting satellite measurements. Flares are categorised into three types, with grade C being the least powerful, grade M a medium-level flare, and grade X being the most powerful of all. NASA’s Solar Dynamics Observatory (SDO) spacecraft captured images of the latest huge flare which was classified as a formidable X1.1.

Scientists tracking the movements of four highly stressed seismic faults that form part of the Bay Area’s densely populated San Andreas system have discovered worrying surface mobility which suggests that they could burst forth in a major quake at any time.
