because too many ppl die!
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
Magnitude is a measure of the total energy released by an earthquake, while intensity is a measure of the effects of an earthquake at a specific location. Magnitude is a more objective measurement, while intensity can vary depending on distance from the epicenter and local geology.
The magnitude of an earthquake is the amount of energy released at the source of the earthquake and is measured by a seismograph. Intensity is shaking strength of an earthquake at a particular location.
The lag time between the arrival of primary (P-wave) and secondary (S-wave) seismic waves increases with distance from an earthquake's epicenter. This relationship is due to the differing speeds at which these waves travel through the Earth's layers. By measuring this lag time, scientists can estimate the distance to the earthquake's epicenter.
The epicenter of an earthquake is the point on the Earth's surface directly above where the earthquake originated, known as the focus. It is the point where the seismic waves are most intense and where the effects of the earthquake are often most severe.
The impact distance of the earthquake that struck the region refers to how far the effects of the earthquake were felt from the epicenter. It indicates the geographical area affected by the earthquake's shaking, damage, and other consequences.

location distance motion
The effects of an earthquake generally diminish with increasing distance from the epicenter. Near the epicenter, seismic waves are strongest, causing more intense shaking, structural damage, and potential casualties. As distance increases, the energy of the seismic waves dissipates, leading to weaker shaking and reduced impact on buildings and infrastructure. Additionally, geological factors and local soil conditions can influence the severity of the effects experienced at various distances.

The effects of the earthquake in Haiti was that it killed lots of people and destroyed everything.
1) Magnitude 2) Duration 3) Distance from epicenter 4) Location (land vs. water) The effects of any earthquake depend on a number of widely varying factors. These factors are all of: * Intrinsic to the earthquake - its magnitude, type, location, or depth; * Geologic conditions where effects are felt - distance from the event, path of the seismic waves, types of soil, water saturation of soil; and * Societal conditions reacting to the earthquake - quality of construction,preparedness of populace, or time of day preparedness
the effects of the earthquake is watching pornography
The Richter scale is related to the effects of an earthquake rather than the energy released.
Basically the effects of the earthquake is a big tremor and things toppling over.
Yes, an earthquake is a mechanical wave. Movement (oscillations) in geologic formations generate mechanical energy that is transferred into surrounding rock. That mechanical energy radiates out from the focus of the quake, and we can feel or even see the effects at distance.
