An earthquake is caused by a sudden slip on a fault. Tectonic plates are always slowly moving, but they can get stuck at their edges due to friction.When the stress on the edge of a tectonic plate overcomes the friction, there is an earthquake that releases energy in waves that travel through the Earth's crust and cause the shaking that is felt.

Hurricane Floyd was a destructive hurricane that hit North Carolina and New Jersey during the 1999 Atlantic hurricane season. The image above was taken of Floyd near its peak intensity, and because the image is so striking, it has often been attributed to other, more recent destructive storms such as Hurricane Jeanne and Hurricane Katrina .
Common developmental patterns seen during tropical cyclone development, and their Dvorak-assigned intensities. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared ...
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
It caused $30 billion in damage and more than 40 deaths. It was the costliest natural disaster in the history of the U.S. at the time. When the 1992 hurricane season ended, the name Andrew was ...
Within the Dvorak satellite strength estimate for tropical cyclones, there are several visual patterns that a cyclone may take on which define the upper and lower bounds on its intensity. The central dense overcast (CDO) pattern is one of those patterns. The central dense overcast utilizes the size of the CDO.
For hurricanes, that means an increased likelihood of strong storms like 2017’s Hurricane Harvey, which came ashore as a Category 4 storm before being downgraded to a tropical storm that parked ...
