Data Analysis of RAN network records – May 20th event
For each of the three components – South-North (SN, blue), Est-West (EW, black) and vertical (UP, red) – data analysis present time histories (left) and relative acceleration response spectrum (Sa), velocity response spectrum (Sv) and displacement response spectrum (Sd). For each considered station, a comparison between acceleration, velocity and displacement response spectra is presented, according […]
Preliminary Observations by Montalva and Cerda at Universidad de Concepción
Although the 8.2 Mw that struck Iquique this past April 1st was less energetic than the 2010 Maule EQ, the available records show the same surface intensity demand for similar site conditions. The geotechnical and structural damage is much less than the one registered in 2010, the reason will probably be attributed to better site […]
CIGIDEN Preliminary Report
The northern most part of Chile is tectonically characterized by the subduction of the Nazca Plate beneath the South American Plate. The convergence rate at this part is about 65 mm/yr along a vector oriented N75E (1, 2). In the area of the Pisagua‐Patache Seismic Sequence (PPSS), the seismic interaction at the interplate contact occurs […]
