What were the primary and secondary effects of the Mt St Helen's eruption?
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.

Scientists use -------waves to find an earthquake epicenter?
Scientists use seismic waves to find an earthquake epicenter. By analyzing the arrival times of primary (P) and secondary (S) seismic waves at different seismic stations, scientists can triangulate the epicenter of the earthquake.
Primary effects of earthquakes?
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 person located twice as far from the epicenter of an earthquake as another person will notice tat the time between the arrival of the primary and secondary waves will be?
Twice as long. The interval between the arrival of the primary and secondary waves doubles with every doubling of the distance from the epicenter due to the different velocities of the waves.

Primary and secondary refer to the order in which they come out, surface waves are called surface because they resonate close to the surface

Eg. in an earthquake, they are called the primary and the secondary sound waves. grrrrrr
