Large scale rumours: their danger

Maybe you know, Mexico City is a big city which has had a long record of earthquakes. During the last two years, approximately, we have had several seismic events with a short span between each event. In March 20, 2012 I personally suffered through what for me was thestrongest earthquake in my experience, with a seismic reading of 7.9 on the Ritcher scale.

During those days, I was living alone on the 5th floor of an old building. I was writing my bachelor's dissertation when, suddenly, I started to feel a little dizzy but I thought to myself "it is not dizziness, it is an earthquake". My building was located near the university, so alarm bells had started to ring confirming my suspicions.

I walked to a secure place but I was feeling a strange and vague sensation of calm mixed with anxiety while the time seemed eternal. I have to say that I imagined the worst picture. After that, I learned that many people had had the same sensations. So, now I can understand in the best way a lot of older people's earthquake experiences.

Recently, we have felt other earthquakes which did not have the same magnitude, but had enough power to alarm Mexico City's inhabitants. This fact has led to several kinds of rumours mainly related to a big earthquake with potential destructive effects.  Of course, this information was without scientific basis, however, sometimes people draw dangerous conclusions when they listen to rumors or neglect the associated dangers.

Fortunately, the Geophysics Institute has done a couple of interviews to clarify some interesting points and to stop this dangerous practice.

Hola Mayra,

Wow,  we went through a very similar earthquake in Seattle about 12 years ago.  Until that time I had wanted to experience an earthquake.  Now... No thanks!

I think that the similarity between "largo" and "large" causes people to think they are the same.  But in English "large" = "grande",  "long" = "largo".  I'm sure you know this, sometimes I make similar mistakes when I'm trying to write a lot of text in Spanish.

We say "on" where in Spanish you say "in" in many situations.  I experience the reverse problem trying to write Spanish and know whether to use "in" or "on".   I'm hoping experience will solve the problem!  

We say "I was dizzy", or "I experienced dizziness".  You could also say "I experienced the state of dizziness", or "I experienced being dizzy",  I'm sure all this will make you dizzy!

"During those days" is ok, you could also say "At that time".

For "I imagined the worst picture" you could also just say "I imagined the worst".

With respect to "Large scale rumours: their danger"  you could also say "Large scale rumour: its danger".  Did you know that the English version is "rumour" and the EEUU version is "rumor"?  Be aware that some of my ways of saying things my be at odds with what an Englishman might say.

¡Muy bueno Mayra!

Big scale rumours: its danger

Maybe you know that Mexico City is a big city which has a large record long history of the disastrous effects of on earthquakes. effects. Since In  the last two years, aproximately, we have had several seismic movements with a diminishing amount of time less span between each event. In March 20, 2012 I personally suffered experienced, what was for me, meant the most strongest earthquake's experience, a seismic event registering 7.9 on the Ritcher scale.

During those days, I was living alone on the 5th floor of an old building. I was writing my bachelor's dissertation when suddenly, I started to feel a little dizzy but I thought to myself "it this is not a dizzyness, it is an earthquake". My building was located near the university and  so the alarms bell had started to ring confirming my suspicions.

So, now I have a better understanding of can understand in a best way a lot of earthquake's mature people's experiences during an earthquake. 

Recently, we have felt others earthquakes,  which had not of the same magnitude, but had had with enough power to alarm the inhabitants of Mexico City's habitants. This has spawned many fact had carried out to several kind of rumours mainly related with to a big future large and  potentially destructive earthquake. of potential destructive effects.Of course, this information have not some these rumours have no scientific basis. however, Sometimes people sprawl are carelessly what when they listen to the warnings or neglect the dangers associated with the earthquakes. (I was not clear on your intended meaning of this last sentence.  I hope this is what you had wanted to say)

Fortunately, the Geophysics Institute has been interviewed done a couple times of interviews to clarify to the public them some of the interesting points related to earthquakes and in an effort to stop this dangerous practice.

Well done Mayra for a very difficult and complex topic! Most of my changes involving rearranging some sentences to help make your topic clearer and  more natural.  Keep up your excellent work!
