Buildings collapsed People buried
epienter or focus or moho or tsunami

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.
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
The Boxing day tsunami was a key impact in global history. I, myself am writing an essay at the moment on the effects of it, the main things you'd need to include would be: What/Where Primary effects Secondary effects How the world helped How they've prepared for future tsunamis hope this has helped :) (bye the way I'm only 13 so sorry if there were any mistakes)
people died
harvest loss, misery to the farmers and poverty
Primary effects : - Death from the flooding - Buildings destroyed - Farms and agriculture in the land is wiped out - Houses are destroyed - Diseases such as cholera are spread through the water from the floods Secondary effects : - Death from diseases in the flood water - Homelessness leads to death from no shelter - No farms = death from starvation , and also poverty in many areas, even ones not affected by the flooding - Companies and business's suffer - Major strain on the economy from having to spend millions to clear up and rebuild etc. Those are the only ones i can think of at the moment, but they should be enough.
primary: - lava flows - ash flows - gas - blasts secondary: - debris flows - mud flows hope this helps
Primary Means, it is individual there is no dependence, But Secondary will allays depends on Primary, If you want to do Secondary, you should complete primary first, There is no precondition to primary, but for Secondary Primary is the Precondition, first you should do primary, then only you are able to do secondary.
