A Wolfram Notebook on Earthquakes |

* To get an overview of all the functionalities available in the Wolfram language and that are related to Earth Sciences, visit Wolfram Language & System Documentation Center.

* You can find dozens of detailed examples on various functions, such as **EarthquakeData**, **GeoGraphics**, **GeogravityModelData** and **FormulaData**.

* By means ** EarthquakeData**, the Wolfram Language provides the most current data on earthquakes in the world, thus making the information easily available for analysis and examination.

* Don't forget that to execute the instruction, you must press Shift + Intro.

**Ex 1**:Find the entity keys of all registered earthquakes of magnitude -1 to 10 within a radius of 100 km around Talca city and store this list in xx:

(List generated according to the Wolfram Alpha Database).

**Ex 2**: Find when each of the earthquakes in list xx occurred:

**Ex 3**: Position on the map the earthquakes labeled from 80 to 90 in list xx, with the earthquake icon:

**Ex 4 **: Obtain earthquakes of magnitude greater than 6.0, occurred within a radius of 100 km around Talca city:

**Ex 5 **: Reduce the search to 50 km around Talca city:

**Ex 6 **: Present earthquakes within a radius of 50 km around Talca and with a magnitude between 7.0 and 8.0:

**Ex 7 **: Present the epicenters of earthquakes occurring within a 300 km radius around Talca city:

**Ex 8 **: Present the Pacific Ring of Fire volcanoes:

For the "Volcanoes" class of the Pacific Ring of Fire have been used: ** ****EntityClass["Volcano","RingOfFire"]**
