Update : Based on my own knowledge of Quito, even a small earthquake like this one is enough to trigger landslides. The Quito unofficial housing areas are seen as one of the most dangerous on the planet.

Update : The earthquake seems to be too weak for the international agencies to report on it.

Update : we can call the data official now as they have been printed on the IGEPN seismological site of Ecuador. This is what is shown : Mag= 4.0; Prof (Depth)= 10.00, Lat= -0.11; Long= -78.41, 2011/10/29 13:50:49 UTC

Update : Unofficially we could gather the following information : epicenter 14 km of Quito, depth 10 km, magnitude 4 (we have to warn our readers that the information is unofficial – coming from a newspaper in Quito)
