Secondary effects are those that result from the primary effects. The fires lasted three days. This blog Landslides have affected humans since they have inhabited mountainous regions. Usually, casualties are induced due to the collapse of buildings, or roads, bridges, tunnels, or other infrastructure failing due to being shaken by the seismic waves. Here are a few others.

Now, in Japan, we are looking at something which may or may not be  the catastrophic meltdown of a reactor in a nuclear power plant. Their gaze, however, is the same as Genthe’s — looking east at billowing plumes of smoke down in the Marina district. The secondary effects are the effects that occur directly as a result of this earthquake shaking and energy release, i.e., the onset of a tsunami wave, or a landslide.

Yesterday’s tsunami is an example of a secondary effect, and a tremendously deadly one. It would be the ultimate secondary effect. 2 Comments/Trackbacks ».
