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
Primary effect.....I think.......
they are secondary because 'after' means it would be after the earthquake has happened
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.
Primary effects are things that happen straight away as soon as the earthquake hits, such as; buildings shake/collapse (depending on how strong the earthquake is) roads crack/fall in, gas and water systems/poles break/burst
A Primary Effect is basically an disaster like earthquakes what happens in the area of the earthquake e.g buildings f-d damaged like tat secondary effects well....... U dint ask 4 tat. -I.E_ Revstar deadshotyz
Primary waves are the fastest seismic waves originating from an earthquake, traveling at 6 to 7 km per second. Secondary waves travel at about 3.5 km per second.
an s-p interval is the time that it takes for the secondary waves of an earthquake after the primary waves hit.

people died
they are primary, secondary, and surface waves
20,000 people dead
Gujarat lies around 400 km from the plate boundary that is located between the Indian Plate and the Eurasian Plate. This earthquake that struck Gujarat was caused by rifting reverse faulting on reactivated rift faults
Primary and secondary refer to the order in which they come out, surface waves are called surface because they resonate close to the surface
floodinggg :D
how far away you are from the focus of an earthquake
P waves (primary waves) and S waves (secondary waves).
Primary (P) and Secondary (S) waves
the time it takes for the secondary wave of an earthquake after the primary wave hits
Eg. in an earthquake, they are called the primary and the secondary sound waves. grrrrrr
