Important of determining the epicenter of an earthquake : The major reason for establishing the epicenter is to identify the fault that caused the earthquake. If the fault was previously unknown (like in the case of the 2010 Canterbury earthquake), it is significant because it indicates that the area's hazard models need to be updated.
How can we locate the epicenter of an earthquake?
When seismic signal (or waves) from the same earthquake are recorded at least three or more distantly located seismic stations, we can use the arrival time (of various phases) of these seismic waves at different seismic stations to locate the concerned earthquake (hypocenter) and its epicenter.
What is the difference between an epicenter and a fault?
When the earthquake is large, the fault is large. An earthquake has to start someplace on that fault, and that someplace is called the “hypo-center”. The hypo-center is the easiest and most accurate part of the earthquake to locate, so seismologists use the point on the ground directly ab An epicenter is the location of a part of something larger.
Why do we need to study earthquakes?
Yet, time to time this area of research has been rekindled by the scientific community because studying earthquake is the only way to counter the element of surprise that an earthquake brings with it. Can we locate the epicenter if we only have seismic recording station?
Why is it important to know the epicentre of an earthquake?
Thus knowing epicentre is the first step in planning post-earthquake rehabilitation and relief measures, in forewarning of tsunami-related hazard and in assuring of minimum loss to life and property if it is the deserted or inhabited region.
How to identify the epicenter of an earthquake?
Scientists can identify the epicenter of an earthquake by measuring the time between the P-waves and S-waves of an earthquake. Learning Outcomes. Once you are finished, you should be able to: Explain the difference between the epicenter and the hypocenter of an earthquake.
Where is the most important location for an earthquake?
There are two important locations in any earthquake. The most important is the hypocenter, or focus of the earthquake. This is the point where the earthquake truly begins, deep under the ground and located at a tectonic plate boundary, the border between two of the fragments the Earth's crust is broken into.
Where are the three circles from three seismographs?
Three circles from three seismographs will overlap at the location of the epicenter. Let's review. The epicenter is the point on the surface of the Earth directly above the hypocenter of an earthquake. The hypocenter is the place where the rupture of the plate boundary that led to the earthquake first happened.
What equipment is used to measure earthquake strength?
The simplest requires the positioning of seismographs, equipment that measure the strength of ground tremors and earthquakes, around the area. It is possible to use a process of triangulation to figure out the location of the earthquake.
Where is the epicenter on the Earth's surface?
It is where the plate boundary begins to rupture. The epicenter on the other hand, is the point on the Earth's surface directly above the hypocenter. This is a more useful measure for human reporting because it can be shown on a map.
Can an earthquake run across a large section of the plate boundary?
But this isn't always true. If an earthquake is particularly large, it may run across a large section of the plate boundary. In this case, the epicenter might only be one of many hotspot locations and damage could be greater elsewhere.
Answer
The main importance in determining the epicentre is so that the fault that ruptured causing the earthquake can be identified. ... If the fault is previously unknown (such as the 2010 Canterbury earthquake), then it is important because it means that the hazard models for the area need improvement.
Answer
The major reason for establishing the epicenter is to identify the fault that caused the earthquake.
