Earthquake in Iquique

On April 1st of this year

Esto es correcto.  También, puedes decir "On the 1st of April of this year"  

ocurred a big earthqueake 

escribe "earthquake".  

in the city that I live currently (Iquique, Chile).

Al revés y con "in" así

"in the city that I currently live in."

The movement was horrible, and I said myself, "oh my God, this is the end of my life".

"The movement from the earthquake was horrible and I said to myself," es mejor pero yo entendí.

Although the scale of the earthqueake was 8.2, only 6 people died. The following day my city seemed to be a lonely town because nobody was outside of their houses, all the people were inside of them trying to save their belongings.

The positive aspect of my country is that Chileans are always prepared in case of any movement.

Esto es bueno, pero, para mi esto es mejor: "The good thing about my country is that Chileans are always prepared for an earthquake."

You did well Natalia.  You had very few errors and I understood your message.  I would have been scared!  There are not many earthquakes where I live.
