When something happens over a long period of time
it means its secondary effects are magnified by the size of the population in the area affected
Rising salt in the soil
yes
We can divide the effects of an earthquake into those known as the primary effects and those known as the secondary effects. Primary effects of an earthquake are those resulting directly from the earthquake itself. These include; buildings collapsing; roads cracking; bridges giving way; shattering of glass and injuries / deaths resulting from these. Secondary effects are those that result from the primary effects. For example ground shaking may result in the cracking of gas and water pipes (primary effects) this can result in severe fires due to explosion from escaping gas and difficulties in putting out fires due to lack of water from burst mains (secondary effects). Other secondary effects include, homelessness, business going bankrupt and closing etc.
Is it f d a approved
floodinggg :D
The difference between them is that Primary effects happen during the earthquake e.g. Casualties, Damage to parking structures & free ways. But with Secondary effects they happen after an earthquake e.g. Fire, Landslides & Liquefaction
people died
Buildings collapsed People buried
The primary effector creates a signal that can diffuse within the cell. This signal is called the "secondary messenger." (The neurotransmitter is the first messenger.) The secondary messenger may then activate a "secondary effector" whose effects depend on the particular secondary messenger system.

The secondary effects of the Japan earthquake were fires, gas line explosions, and a resulting major tsunami, which in turn was responsible for damage to the Fukushima Daiichi nuclear power plant. Destruction to Plumbing and sewer system could led to disease due to build up of waste. Additional secondary effects were collapsed bridges and other structures due to destabilization caused by the strong shaking.
