What a 2011 beginning! less than hour ago a mayor important earthquake hit on the south of Chile, again. According to the USGS report the magnitude is 7.1 with an epicenter location on ground!!! close to the city of Araucana.
There are some videos running on internet right now from the moment of the earthquake, it looks like there is no much damage just an interesting shaking…
As we can see in the “Did you feel it” section on the USGS website, a lot of people report this event but the reported intensity is between Light and Moderate.
There are no report of mayor building damage, we are waiting any report from landslides and co-seismic effects (liquefaction, lateral spreading, LANDSLIDES!!). This post is going to be actualized soon if is necessary .
UPDATE: It looks like there was just a shaking, one of my friends from the Geological Survey of Chile (SERNAGEOMIN) just told me by phone that there is no tsunami warning, or any mayor damage in the nearest cities, of course no landslides at all, and this is the official report from the University of Chile (6.9 Ml).
And yes! finally this project is going to be alive. Almost one year from the main idea: the evolution of EnMorrenas to TerraMotus, and why? because Enmorrenas is mainly dedicated to glaciers environments and is in Spanish (don’t worry, all of this post is going to be in Spanish at Enmorrenas from now).
So, this is the first picture ever of this new era: The Maca Landslide, here the dossier
- Location: Maca, Arequipa, Peru
- Lithology: Quaternary lake deposits
- Status: ACTIVE
- Speed: Some meters per year
- Damage: The town of Maca
We can clearly see how the main mass of the landslide is stabilized by the “andenes” but he problem is still there, the bad use of the agriculture water is creating a new scarp inside the town. If you are so nosy, you can see in the top of the picture a small mark of a debris flow, quite common in this part of the Andes.
Well, this is the beginning of TerraMotus, wish me luck in the comments and have a geodynamic 2011!!!
All the best for you!
And Yes! this is a landslide blog, but is going to be a little different from the others, and why? because I’m going to talk about of these unknown south-american and some european landslides.
Well, that all for now, I’m preparing my first post about one of the biggest landslides in the last rainy season in Peru.
