Top 10 “Overdue” Earthquake

Locations

(No particular order)

1- California: This group of earthquakes is located on the North American plate, as well as the fault line experiencing plate movement coming from the North. This cluster of earthquakes is located on the coast line of California, near the San Adreas Fault. It is also extremely low populated of earthquakes that occurred in 2010. This area has several big and significant earthquakes.


Locations


2-Alsaka: This cluster of earthquakes is located on the Pacific plate region, as well as on a subduction zone. Plate movement is occur also. High population of both Big and Significant earthquakes. 3-4 earthquakes occurred in 2010. Meaning earthquakes are overdue to occur in this area.


Locations


3- Guatemala: The Plate boundary that the earthquakes are found upon is located on the Cocos Plate. This boundary are covered in both big and significant earthquakes, yet there are few earthquakes that took place in 2010.


Locations


4- Chile/Peru: These earthquakes are located in the South American Plate, which is experimenting plate movement from both the east and the west. This western coast line is covered in both significant and big earthquakes, yet 7-9 that took place in 2010.


Locations


5-Turkey: This massive clump of big and significant earthquakes in located in the Eurasian plate and plate forces are coming from the west. This earthquakes are sitting there, waiting to erupt, yet in 2010 it seems that only 1-5 earthquakes occurred in this region.


Locations


6-Burma/China: There are significant amounts of big and significant earthquakes in the Burma and China area, yet the number of earthquakes that happened in 2010 (only one dot), allows me to believe that a great number of quakes will be coming shortly.


Locations


7-Japan: These earthquakes are in the Eurasian Plate.This fault line is lined with both big and significant earthquakes, as well as few earthquakes that occurred in 2010. Based on the number of big and significant earthquakes, I predict this area of Japan is awaiting an earthquake.


Locations


8-Philppines: These earthquakes are in the Eurasian Plate. This fault line is has a clump of big and significant earthquakes, there are only few earthquakes that happened in 2010. The Philippines are also a common earthquake area.


Locations


9-Afganistan: These earthquakes are in the Eurasian Plate. This area is scattered with with big and significant earthquakes. There seems to be around 5 dots in the area, meaning earthquakes have occurred in 201. Yet since the area is quite large and populated with both big and significant earthquakes, I predict that Afghanistan is over due for an earthquake.


Locations


10-Mongolia: These earthquakes are in the Eurasian Plate. This area has no earthquakes that occurred in 2010, and big and significant that have occurred in the past. Since no earthquakes have occurred in the present time I believe Mongolia is overdue for large a earthquake.

Response

Question:What new tools or

techniques are seismologists using to help them better

predict earthquakes?

Response:With the on going devolvement of satellite methods

(from NASA), seismologists are hoping to be able to predict both time and location of future earthquake.

An example is the Interferometric-Synthetic Aperture Radar (InSAR) method. This is when two

radar images of an tectonic area go through a process called data fusion (combination of data), and any movement in the ground are detected at the surface. This method with the combined with satellite views allows seismologists to determine were high strains are beginning to form. Another

new technique/tool that seismologists use is infrared (IR) radiation, when attached to a satellite

IR is able to see hot spots. When seismologists examined infrared data that had been collected by

one of NASA’ s satellites, it was dicovered a warning in the ground, just before a powerful

earthqauke hit Gujarat.

Response

Question:What have you learned

about earthquakes and earthquake

prediction?

Response:Seismologists look at where

earthquakes have occurred in the past (big

and significant earthquakes), as well as how recent the area has

experienced an earthquake and the

magnitude. Also they use Infrared Radiation and

satellites to discover hot spots.

Response

Question:What factors influence

earthquake prediction?

Response:Seismologists use IR, satellites

and Interferometric-Synthetic Aperture Radar to detect

movement in the ground, as well as hot spots. When

Seismologists use Infrared Radiation from satellites they are able discover warnings in the ground. New technology influences how seismologists

are able to predict earthquakes, based upon

new techniques that surface.

Response

Question:Where on Earth do most of the really big earthquakes strike?

Response:• Most earthquakes occur in

the circum-Pacific seismic belt, which is found along

the rim of the Pacific Ocean. This is were 81 %

of the worlds largest earthquakes occur. This belt extends from Chile, and stretches northward along South American coast. This belt 70,000

deaths in Peru the 1970’s.
