a blue moon was a metaphor for something that was impossible or absurd. Following the 1883 eruption of the Krakatoa volcano, it was said the moon appeared blue in some parts of the world, which led to the term "blue moon" being referred to as a rare event instead...

hazards, most of the area seems to be safe. Figure 1 which showcases flood hazards in my area, illustrates that there are predominantly zones where no base flood elevations have been determined as well as areas that are outside the 0.2% annual chance floodplain. My home area as well as ...
Seldovia is 80 miles from the volcano, on the far side of Cook Inlet. Two eruptions are captured in the photos, the first at 11:20 pm on March 27, and the second two hours later. The camera, a Canon Digital Rebel XTi with a Canon 70-200mm L lens, was only barely able to ...

Landslides, rock-slides, avalanches, slumps are widespread after the shaking of the ground. These are the secondary hazards that trigger after the earthquake. Landslides caused by the slope failure are triggered by a strong movement that occurs under the ground and causes damage to infrastructure an...

Why are there so many volcanos in Iceland? Iceland sits on a tectonic plate boundary that continually splits apart, pushing North America and Eurasia away from each other along the line of the Mid-Atlantic Ridge. A powerful mantle plume, an area that is hotter than the surrounding magma,...
