The city of Les Cayes
, Haiti’s third-largest city, was the closest to the epicenter of the earthquake. The city suffered extensive damage including many collapsed homes, places of worship, and commercial buildings.
Which major city is closest to the epicenter?
Among major cities,
Kobe
, with its population of 1.5 million, was the closest to the epicenter and hit by the strongest tremors.
Which of these cities is closest to the epicenter of the earthquake Hinche?
The city of Les Cayes
, Haiti’s third-largest city, was the closest to the epicenter of the earthquake. The city suffered extensive damage including many collapsed homes, places of worship, and commercial buildings.
What is the epicenter of an earthquake?
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. … These are smaller earthquakes that occur afterwards in the same place as the mainshock.
Which of the following makes the correct distinction between the focus and epicenter of an earthquake?
What is the difference between the focus and epicenter of an earthquake?
The focus is the point within the earth where seismic waves originate
; it is centered on the part of the fault that has the greatest movement. The epicenter is on the earth’s surface directly above the focus.
Which 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.
Which part of Haiti was affected by the earthquake?
Haiti earthquakes and recovery timeline
January 12, 4:53 p.m.: A magnitude 7.0 earthquake hits Haiti, on
the island of Hispaniola, near Léogâne
, about 15 miles west of the capital, Port-Au-Prince.
Why do we need to know the epicenter of an earthquake?
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.
What does the P stand for in P wave?
Compressional waves are also called P-Waves, (P stands for
“primary”
) because they are always the first to arrive.
What is the distance between the epicenter and the station for the earthquake recorded?
Hence, the distance from the earthquake epicenter to the seismic station is
2,100 miles
.
Where can we find the earthquake epicenter?
The epicenter is the
point on the earth’s surface vertically above the hypocenter (or focus)
, point in the crust where a seismic rupture begins.
Where do earthquake epicenter usually found?
The epicenter is the point
on the land surface that is directly above the focus
. In about 75% of earthquakes, the focus is in the top 10 to 15 kilometers (6 to 9 miles) of the crust. Shallow earthquakes cause the most damage because the focus is near where people live.
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 are the 3 fault types?
There are three main types of fault which can cause earthquakes:
normal, reverse (thrust) and strike-slip
. Figure 1 shows the types of faults that can cause earthquakes. Figures 2 and 3 show the location of large earthquakes over the past few decades.
What is the name of the instrument used for measuring earthquake?
Seismographs
are instruments used to record the motion of the ground during an earthquake.
Which measure of an earthquake depends on how close?
The Richter scale
calculates an earthquake’s magnitude (size) from the amplitude of the earthquake’s largest seismic wave recorded by a seismograph. On the original Richter scale, the smallest earthquakes measurable at that time were assigned values close to zero on the seismograph of the period.
