Use of resistivity measurements to detect urban caves in Mexico City and to assess the related hazard
resistivity measurements urban caves Mexico City related hazard
2009/12/14
In the XIX century when Mexico City was much smaller than at present, there was non-regulated mining of building materials in a region of tuffs northwest of the city in an inhabited countryside. With ...
Spectral and multifractal study of electroseismic time series associated to the Mw=6.5 earthquake of 24 October 1993 in Mexico
Spectral and multifractal study electroseismic time series
2009/12/14
In this work we present a spectral and multifractal study of the electric self-potential fluctuations registered in an electroseismic station located at 100km from the epicenter of an earthquake (EQ) ...
Drillers Hit Promising Gas-Hydrate Deposits in Gulf of Mexico--Potential Alternative Fuel, Usually Too Thinly Spread to Exploit（图）
Drillers Hit Gas-Hydrate Deposits Mexico--Potential Alternative Fuel
2009/12/10
U.S. scientists working on a research vessel in the Gulf of Mexico have made the most promising discovery so far of marine gas hydrate, a possible new energy source. Globally, gas hydrate--an icelike ...
Assessing lahars from ice-capped volcanoes using ASTER satellite data, the SRTM DTM and two different flow models: case study on Iztaccíhuatl (Central Mexico)
ice-capped volcanoes ASTER satellite data the SRTM DTM and two different flow models Iztaccíhuatl (Central Mexico)
2009/12/30
In this study, analysis of the glaciers on Iztaccíhuatl shows a dramatic retreat during the last 150 years: the glaciated area in 2007 corresponds to only 4% of the one in 1850 AD and the glaciers are...
Geomagnetic anomalies observed at volcano Popocatepetl,Mexico
Geomagnetic anomalies volcano Popocatepetl Mexico
2010/1/27
Results of the ULF geomagnetic monitoring of the volcano Popocatepetl (Mexico) and their analysis are summarized and presented for the period 2003–2006. Our analysis reveals some anomalies which are c...
A statistical analysis of electric self-potential time series associated to two 1993 earthquakes in Mexico
statistical analysis electric self-potential time series earthquakes in Mexico
2009/12/30
Recent studies related with earthquake prediction involve statistical studies of the ground electric self-potential behavior. Published results about the complexity of this kind of processes encourage...
Volcano Popocatepetl,Mexico:ULF geomagnetic anomalies observed at Tlamacas station during March–July,2005
Volcano Popocatepetl ULF geomagnetic anomalies Tlamacas station
2009/12/30
In this paper the first results of ULF (Ultra Low Frequency) geomagnetic anomalies observed at Tlamacas station (Long. 261.37, Lat. 19.07) located at 4 km near the volcano Popocatepetl (active volcano...

Geophysical and geochemical signatures Gulf of Mexico seafloor brines
2010/1/12
Geophysical, temperature, and discrete depth-stratified geochemical data illustrate differences between an actively venting mud volcano and a relatively quiescent brine pool in the Gulf of Mexico alon...
Possible seismogenic origin of changes in the ULFEM resonant structure observed at Teoloyucan geomagnetic station,Mexico,1999-2001
Possible seismogenic origin changes ULFEM resonant structure Teoloyucan geomagnetic station
2009/12/29
The evolution of the ULF resonant structure observed at Teoloyucan geomagnetic station has been provisionally studied in a possible relation with seismic activity in Mexico in the period 1999-2001. Tw...
