Are focus waves vibrations that are released during an earthquake?
No, It's Seismic Waves.
When do seismic waves occur?
when an earthquake occurs
During an earthquake do seismic waves move outward from the focus in all directions?
Yes, they do.
Which type of seismic waves will reach a nearby city first when an earthquake occurs?
Primary and secondary waves.
Is an earthquakes epicenter underground?
An earthquake epicenter is always located on the ground right about the focus. The focus occurs where one piece of land slides against another. The sliding can be up and down or sideways or a combination of up-down and sideways. There can also be surface indications. The main action occurs underground.
How is a focus of an earthquake related to seismic waves?
the bigger the waves the bigger the earthquake
What type of wave can be used to determine the location of an earthquake focus?
Seismic waves can be used to determine the location of an earthquake focus. These waves are triggered by tectonic plates.
The energy waves that produce an earthquake begin on the surface or within the earth?
The energy waves form at the focus which is the location within Earth along a fault at which the first motion of an earthquake occurs
Are focus waves vibrations that are released during an earthquake?
No, It's Seismic Waves.
What does secondary waves and primary waves tell geologist?
how far away you are from the focus of an earthquake
When do seismic waves occur?
when an earthquake occurs
These waves are slower than those that originate at the focus.?
These waves are slower than those that originate at the focus.
What are the two names for where an earthquake originates?
The focus is the point underground where the earthquake originates.The epicentre is the point on the surface directly above the focus, where earthquake waves seem to spread out from.
What is the main idea of seismic waves carry the energy of an earthquake?
Focus
Which causes more damage a shallow focus or deep focus?
Typically, a shallow focus earthquake will cause more damage than a deep focus earthquake. Shallow focus implies the source of the earthquake is near to the surface, so the waves will lose lesser energy than the deep focus earthquake waves while travelling through the Earth. But it depends on other factors too such as local stratigraphy, and subsurface conditions.
What is directly below the epicenter of an earthquake?
Directly below is the focus. The focus is the place where the earthquake originally starts. From there, shock waves move in all directions.
What waves will arrive at a seismograph station first after an earthquake?
P waves arrive first at a seismograph station after an earthquake. The P waves are followed by S waves, and then surface waves.
