What does the term earthquake epicentre mean?

The tectonic plates placed deep inside earth's crust [range may vary, say 5-100km]. As such, epicentre is defined as the centre point of the tectonic activity projected on earth's surface. Thus the epicentre can also lie on the surface of Sea/ Ocean also. Ocean water remains only up to 10 to 12 km deep [maximum being Marina Trench]The tectonic activity lies much below !!The epicentre is the point on the earth's surface directly above the earthquake's focus or hypocentre (the point within the earth where the fault rupture or movement actually occurs).As such, the seismic waves produced by an earthquake radiate away from this point. This is similar to the way waves or ripples in a pond move outwards in concentric circles from the point where you throw a stone into the water.


How many seismographs must be used to locate the epicenter of an earthquake?

At least three seismographs are needed to locate the epicenter of an earthquake. By comparing the arrival times of seismic waves at different stations, scientists can triangulate the epicenter. With three or more points of arrival time data, they can pinpoint the exact location of the earthquake epicenter.


What is required by all living things?

Living things must be able to acquire nutrients and energy. This also means that living things must have a metabolism.


If the rainforests are getting cut down does it affect animals?

The Amazon rainforest produced 20% of the entire world's oxygen, as it is rich in plants. When it's being destroyed, the oxygen levels will affect us. 25% of all pharmaceutical drugs come from the plants in the rainforest. 99% of the rainforest has yet to been tested. Scientists know of potential ingredients that can be found in the rain forests that can create drugs to treat cancer, Alzheimer's, AIDS, and many others. Unfortunately, scientists also believe that all rain forests, including the Amazon, will be destroyed within the next 40 years (every second 1.5 acres are burned, logged, and/or cleared away.). So very likely, by the time we can actually find a cure for cancer or AIDs, the Amazon rainforest will be destroyed, because many landowners and timber harvesters believe the rainforest to be only as valuable as the resource inside of it. Cutting down any forest affects humans, and the natural cycles of all living things. At some point in the future we as humans may upset the natural balance of the Earth, and cutting down forests may be taking us closer to upsetting that balance.


Is rifting the opposite of subduction?

No, rifting is not the opposite of subduction. Rifting is the process where tectonic plates move apart, creating new crust, while subduction is the process where one plate is forced beneath another, leading to the destruction and recycling of crust.

What is the definition of an epicentre of an earthquake?

The epicentre of an earthquake is the point on the earth's surface away from which the seismic waves produced by an earthquake radiate. This is similar to the way waves or ripples in a pond move outwards in concentric circles from the point where you throw a stone into the water. As such the epicentre is the point on the earth's surface directly above the earthquake's focus or hypocentre (the point within the earth where the fault rupture or movement actually occurs).
