Seismology and earthquakes in Chile: How are movements of the Earth studied?

May 9, 2012

Why does Chile have seismic events? What lies beneath the surface of the earth? What is seismology and how does it help us? The answers to these questions will be part of the conversation in the third Scientific Café, which will be led by Dr. Diana Comte, a seismologist from the Universidad de Chile.

More than 150 persons have attended the sessions of the Scientific Cafés that have taken place at the Confitería Torres the last Wednesday of each month at 6:30 pm. The next one will be the turn of the theme of geophysics and Dr. Diana Comte; a seismologist from the AMTC-Faculty of Physical Sciences and Mathematics from the Universidad de Chile invites us to talk about the earthquakes in our country.

How do they originate? •What are their stages? How do they produce tsunamis? These questions and the issue of what safety measures should be taken in anticipation of seismic events will be among the themes of the latest session of the Scientific Café organized by the Millennium Nucleus for Basic and Applied Magnetism of the Universidad de Santiago.

The seismologist will be accompanied by Consuelo Valdés, the Executive Director of the Mirador Interactive Museum (MIM) and Gonzalo Argandoña, President of the Association of Scientific Journalists (ACHIPEC), and Dr. Eugenio Vogel, a professor of the Universidad de la Frontera and a participating scientist in the Millennium Nucleus will act as moderator.

Each encounter is broadcasted on the first Monday of each month from 8:00 to 9:00 pm by the radio station of the Universidad de Santiago de Chile (USACH). The conversation with the research Dr. Diana Comte will be transmitted on Monday, June 2 at 94.5 FM.

The “Scientific Café” is funded by the Millennium Scientific Initiative “Basic and Applied Magnetism” of the Universidad de Santiago de Chile (USACH), with support of the Fund for Innovation for Competitiveness of the Ministry of the Economy and the Center for the Development of Nanoscience and Nanotechnology (CEDENNA), the Radio USACH and the network of university radio stations of Chile.

More about Dr. Diana Comte

Dr. Comte is dedicated basically to “using” the seismic events. She takes seismic tomographies to visualize in 3D the important elements that are below the surface of the earth, such as large mineral deposits and geothermal fields. In both cases, states the seismologist and researcher from the Universidad de Chile, “seismic waves from the process of subduction that pass through underground structures, allowing us to define the physical characteristics of these structures, such as the degree of fracturing, the presence of fluids and their temperatures and more competent rocks. All of this provides better knowledge of mineral deposits and geothermal fields”.

As well, when a major earthquake takes place, field research is conducted close to the process of replicas, rapidly installing networks of seismological stations in the area affected by the earthquake.

Finally, seismicity induced by mining operations is also analyzed and active seismic faults are identified.
