Another from Tarapaca. I guess small releases are better than a built up boom.
According to seimologists from University of Chile a 9 mag EQ is incubating in north Chile. Waves up to 20 meters can be produced.
"Chilea University geophysicist, Armando Cisternas, claims that in the region between Arica and Antofagasta a 9 mag EQ is expected, what will cause a 12 meters movement of two tectonic plates one under the other (Nazca and Sudamericana) and waves up to 20 meters. The professor affirmed that those plates move 8 cm each year and the energy has been accumulating for 130 years, since the great 1877 earthquake. All the convergence between the two plates has deformed them, but didn't cause the rupture yet. Every year this pressure increases".
According to the earthquakes Cisternas 1995 in Antofagasta (grade 8.0 Richter) and the Tocopilla in 2007 (degree 7.3 Richter) are just earthquakes in areas bordering the area where you expect a big break. "There have been earthquakes around that area. An earthquake of magnitude 7 is about 360 times smaller than the 8.8 Richter Cauquenes and that earthquakes in the area that was broken in 1877 are small compared to that must return to occur. " Says that this area has not been broken, the efforts are cumulative and not take a long time to produce the rupture of the zone between the Nazca Plate and South American Plate , including Antofagasta and Arica. "Maybe in 10 years, maximum 20 .
