Scientists use
triangulation
to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs
What can scientists use to identify where earthquakes will most likely occur?
Earthquakes occur along the plate boundaries; however, the exact location of an earthquake is determined by using
seismographs
. A seismograph is an instrument used by the scientists (known as seismologists) to record an earthquake. A seismogram is the recording made by a seismograph.
Where are earthquakes most likely to occur plates?
The Earth’s crust (the outer layer of the planet) is made up of several pieces called tectonic plates and most earthquakes occur
along their edges
. The plates under the oceans are called oceanic plates. Plates that are not under the ocean are continental plates.
Which part of the plate boundary map will earthquake most likely to occur?
Most earthquakes occur at
the boundaries where the plates meet
. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults, and subduction zones.
Which of the following can scientists use to identify where earthquakes will most likely occur quizlet?
With today’s advanced technology, scientists are able to predict when an earthquake will occur. Scientists can identify where earthquakes will most likely occur.
The Richter scale
measures strength while the Mercalli intensity scale measures the effects of an earthquake.
What are the 10 causes of earthquake?
- Groundwater extraction – decrease in pore pressure.
- Groundwater – increase in pore pressure.
- Heavy rain.
- Pore fluid flow.
- High CO2 pressure.
- Building dams.
- Earthquakes.
- No earthquakes (Seismic quiescence)
What is the origin of an earthquake called?
The location below the earth’s surface where the earthquake starts is called
the hypocenter
, and the location directly above it on the surface of the earth is called the epicenter. … The largest, main earthquake is called the mainshock.
Where do earthquakes occur most often and why?
Over 80 per cent of large earthquakes occur
around the edges of the Pacific Ocean
, an area known as the ‘Ring of Fire’; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
What country has the most earthquakes?
For which country do we locate the most earthquakes?
Japan
. The whole country is in a very active seismic area, and they have the densest seismic network in the world, so they are able to record many earthquakes.
Can earthquakes be predicted?
While part of the scientific community hold that, taking into account non-seismic precursors and given enough resources to study them extensively,
prediction might be possible
, most scientists are pessimistic and some maintain that earthquake prediction is inherently impossible.
What causes tectonic plates to move?
Earth’s crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. …
The heat from radioactive processes within the planet’s interior
causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
In which two places do divergent boundaries occur?
Divergent boundaries are occur in
oceans and lower mantle
.
How do earthquakes occur at divergent plate boundaries?
Earthquakes at divergent plate boundaries are distributed with predictable locations and depths. Earthquakes at divergent plate boundaries occur
as new crust is created and other crust is pushed apart
. This causes the crust to crack and form faults where earthquakes occur.
What is the most uncommon type of earthquake?
Just a few times in a century, somewhere on the globe, a rare
“tsunami earthquake”
occurs. These are mysterious because, while they’re just medium-sized as earthquakes go, they cause disproportionately large and devastating tsunamis.
How do earthquakes take place quizlet?
An earthquake occurs
when the rocks break and move as a result of stresses caused by plate movements
. Most earthquakes occur on the edge of plates, especially where one plate is forced under another such as happens off Sumatra or past another as occurs in California.
Which regions are often the site of earthquakes quizlet?
Where do most earthquakes occur? Most earthquakes occur at
plate boundaries
. Divergent, transform, and convergent. shallow depths and are relatively weak earthquakes.
