How does an area's distance from the epicenter effect the amount of damage an earthquake will do?
The proximity of the epicentre to populated or urban areas will effect the damage caused as the closer the earthquake's epicentre, the more energy will be retained by the earthquake waves and so the greater their capacity to cause damage.
Why might an earthquake's primary waves but not secondary waves reach a location on the other side of the world from the epicenter?
The primary wave is traveling faster than the secondary wave, so the farther you are from the epicenter the greater the distance. Think about a race. At the beginning the racers are close to each other, but as they start moving away from the starting point the distance between the racers is greater.
What does the height of the jagged lines on a seismograph indicate?
It indicates that it is greater for a more severe earthquake or for an earthquake close to the seismograph.
How many times greater is the maximum ground motion of a magnitude 5 earthquake compared with that of a magnitude 3 earthquake?
The maximum ground motion of a magnitude 5 earthquake is 100 times larger than a magnitude 3 earthquake.
Which state in the US has experienced a major earthquake magnitude 7.0 or greater in the last 200 years?
England China
When an earthquake accurs where could shaking be greater?
Above epicenter.
Is the greatest intensity of an earthquake always found in the epicenter?
No, the greatest intensity of an earthquake is not always found at the epicenter. The intensity of an earthquake can vary at different locations depending on the distance from the epicenter, the depth of the earthquake, and the local geological conditions. In some cases, the intensity may be greater at locations further away from the epicenter due to the way seismic waves propagate.
Where is shaking be greater if there is an earthquake?
its where it started from so there is going to be more pressure there
How does an area's distance from the epicenter effect the amount of damage an earthquake will do?
The proximity of the epicentre to populated or urban areas will effect the damage caused as the closer the earthquake's epicentre, the more energy will be retained by the earthquake waves and so the greater their capacity to cause damage.
Why does the time between the arrival of the P wave and the S wave become greater and greater as you get farther away from the epicenter?
It is because the epicenter decreases their strenght as it is closer to it
Where would damage be greater - closer to the epicenter or farther away?
No because the epicenter is right on top of the center of the quake.
Does an earthquake begins at the epicenter?
The epicenter is the point on the earth's surface directly vertically above the hypocenter (or focus) point in the crust where a seismic rupture begins.The epicenter is only "far from the center" on very deeply centered earthquakes where the hypocenter (or focus) point in the crust is very far from the surface. Many earthquakes are shallow.The depth of the hypocenter (or focus) point can be categorized as shallow (up to 70 km or 43.5 miles below the surface), intermediate (70 to 300 km), or deep (greater than 300 km or 186 miles).
Was Japan's earthquake expected?
Perhaps not expected but certainly not surprising either. The March 11 earthquake was preceded by a series of large foreshocks over the previous two days, beginning on March 9th with a magnitude 7.2 event approximately 24.8 miles from the epicenter of the March 11 earthquake, and continuing with another three earthquakes greater than magnitude 6.0 on the same day.
What is an earthqake that is in the greater antilles?
Wherever an earthquake happens, it is still an earthquake.
Is data about an earthquake from two seismographic stations enough information to locate the epicenter?
From Science Explorer Prentice Hall Earth Science: " Geologists use seismic waves to locate an earthquake's epicenter. Seismic waves travel at different speeds. P waves arrive at a seismograph first, with S waves following close behind. To tell how far the epicenter is from the seismograph, scientists measure the difference between the arrival time of the P waves and S waves. The farther away an earthquake is, the greater the time between arrival of the P waves and the S waves." Did this help?
Is an earthquake that measures four ten times greater than an earthquake with a measure of three?
yes it does and an earthquake that measures four is 100 times greater than one with a measure of 2 and so on
Would an earthquake be more severe if it had a higher or lower magnitude?
An earthquake with a higher magnitude would generally be more severe. Magnitude measures the amount of energy released by an earthquake, so a higher magnitude indicates a stronger earthquake with more potential to cause damage. However, the severity also depends on other factors including the depth of the earthquake, population density, and building infrastructure in the affected area.
