Contributions were made by authors and projects from various Latin American countries, including Mexico, El Salvador-USA, Colombia-USA, Argentina, and Brazil. The geophysical methods include Electrical Resistivity (1D, 2D, and 3D), EM (AMT and MT), Borehole logging, and Seismic (refraction and MASW), which were applied to solve multiple near-surface geological targets.

Can this be used for scanning CFST column with studs
@@ramakumar2009 , what's CFST?
Thank you for this informative video, I look forward to more of your videos.
Thank you for your feedback. I am planning to add more videos this year.
Great job, Hector!
How accurate are the depth measurements?
@@rsan1512 6 to 12 INCHES
Hello Sir, What is the maximum depth this technique can reach?
Buena noche q. Precio tiene
This is a right device for treasure hunting
Are we using roll along method...?
Not in the example shown in the video.
Hello, can you tell me the name of the device and the country of manufacture?
I am happy to sell you a system.
I am working with a Mining company and our biggest setback is when we drill into caves and large voids, would this system give us an underground view of up to 15 meters so we can have an idea of where not to drill? We are mostly mining Limestone and Basalt.
Thank you for this video! It really helped me grasp the basics of ERT and its use in archaeology. ☺⛏
I am very excited and happy to hear that. Reach out to us at cordillerageo.com if you have any questions.
Hello. Can i ask something sir???
Please do so. Thanks
Which scanner do you highly recommend for this kind of work?
Check out the ones called Proceq by Screening Eangle.
@@hectorhinojosa-cgs Why would you recommend the Proceq over the GSSI used in the video?
@@BITEBOC GSSI or PROCEQ brands are very good.
Do you provide a full training on the equipment and the technique with the data interpretation?
Yes I do! Please let me know if you need anything.
with what program you analyse the uderground ? void or cave ?
That software is Voxler.
@@hectorhinojosa-cgs what filter i have to put to be sure that i have a void or cave ?i usually use average filter type and volRender with terrain2 as color map.i also have send an email . thanks.
Stunning video. It just shakes away all the mystery of what people get when they buy resistivity surveys: "here, look at this video. That's what you get." -Perfect.
I'm from India, BTech civil Engg student I appreciate your work, sir.
Thank you!
This is very dangerous. I guess you guys need to modify the Seismic source and find a way in which all the energy can be blocked into the ground. My thought
Yes, I agree. That issue is clear. Both of us pulled back every time we used it. The manufacturer has to improve the seismic source for this model. I use a better and safer seismic source (Buffalo guns) for reflection and refraction seismic surveys.
@@hectorhinojosa-cgs Seismoelectric equipments are very few. I have one that you have to drill and detonate about 0.8meters deep while held onto the ground by stepping on it. I find much better.
Amazing video.
Thank you very much, Marcell! Please subscribe if you have not done it yet.
Thank you, @marcelleyes. What do you like the most about this video? Have you seen the other videos on my RUclips channel yet? I am planning to make more videos. What would you like to see?
Bastante bueno felicidades!!
Muchas gracias tocayo.
Hi prof I hope you have method of finding underground archaeological places with GIS programs
GIS is not the method to find underground targets. GIS is not geophysics.
Pz can you send to me method to explore underground voids
Hi Sam, Please let me know more details about your interest in finding underground voids. Emai me at hector(@)cordillerageo.com

Excelente tra ajo Dr.Hinojosa ya estamos inscritos adela te
Hello Mr. Hinojosa, im geophysics student and i have great in seismic refraction. I do have some questions: -how do choose the position of the source in relation to the the geophones (before the first geophone, in the middle!?)? do you have the same spacing for all these positions? -in the case of the bedrock mapping, we know that the depth of interest should 3 to 5 times the geophones total length, do you control by varying the source, like the farther the source the deeper our geophysical investigation will be? thanks you for your infos!
Hi Kone, I apologize for the super delayed response...Life got in the way... Answer to Question 1: For seismic refraction tomography I like to do it before the first geophone, between each geophone, and after the last geophone. So the more sources/impacts, the better (higher resolution). You can space the source location any way you want. I prefer to use close spacing (1 or 2 m) and equidistant. Answer to Question 2: Yes, the farther the source the deeper the imaging depth, but that also implies that the source is larger. Deeper imaging depths require larger sources.
