The director of the Institute of Geology, UNAM, Elena Centeno said that even if an association exists between seismic and volcanic activities, "does not mean that it shook (in Guerrero and Oaxaca) emissions occurred volcano" Popocatepetl.
At a press conference, the specialist in geology from the Universidad Nacional Autonoma de Mexico (UNAM) indicated that the relationship is derived from the subduction of tectonic plates located in the vicinity of these states.
But he said, the quake of 7.4 magnitude on the Richter scale occurred on March 20, within the limits of Oaxaca and Guerrero, has no immediate relation to the increased activity of the volcano Popocatepetl, since these processes " are relatively slow. "
He said that because "the subducting plate is moving, the introduction to the planet's deep, it melts and bubbles out as melted magma on the surface and those fed the volcanoes on the surface, but the magma to up, it takes thousands of years. "
Thus, the recent seismic activity, probably "will be linked to a rash that can occur within thousands of years because they are relatively slow processes, although they have very fast events such as earthquakes or eruptions," but "not because it occurred shook the emissions from the volcano. "
However, he said, in Mexico, authorities and society must address the importance of prevention and not live in fear before the occurrence of any natural phenomena.
"Rather than worry we 'deal' is that we must create a culture of prevention, this culture include: education on what to do if an earthquake evacuation drills, building codes consider a scenario of strong earthquakes and compliance with these regulations, "he said.
He stressed that the seismic activity in Oaxaca and Guerrero, as well as recent developments in Playa Los Frailes, where he gained ground sea to 811 meters of beach, part of phenomena now occurring in the plate boundaries, but two different faults.
In California, explained, "is coming out background material being formed underwater volcanoes which in turn generate extension failures, ie failure there is stretching and is generating new crust, which is causing the Gulf of California is opened.
"In Oaxaca, is the opposite process, since the plate is being compressed and getting under each other, ie, the crust is being destroyed," he said.
For its part, the researcher of Geology, UNAM, Sergio Rodriguez Elizarrar?s, insisted that even if the periods of recurrence of large-scale phenomena are longer, it is necessary that society and government address all aspects of prevention.
He noted that while nature shows wisdom in that sense, it is necessary to integrate and protect the environment, while citizens become more aware on prevention.
