Lascar Volcano

During the Proyecto de Investigaciòn Sismològica de la Cordillera Occidental (PISCO '94) in the Atacama desert of Northern Chile, a continuously recording broadband seismic station was installed to the NW of the currently active volcano, Lascar. For the month of April, 1994, an additional network of three, short period, three-component stations was deployed around the volcano to help discriminate its seismic signals from other local seismicity. During the deployment, the volcanic activity at Lascar appeared to be limited mainly to the emission of steam and SO2. Tremor from Lascar is a random, «rapid-fire» series of events with a wide range of amplitudes and a quasi-fractal structure. The tremor is generated by an ensemble of independent elementary sources clustered in the volcanic edifice. In the short-term, the excitation of the sources fluctuates strongly, while the long-term power spectrum is very stationary.

AbstractOn the 9th of January 2001 a seismic swarm on the southeastern flank of Mt. Etna at 3.5 km beside sea level (b.s.l.), caused co-seismic variations on short and long baseline tiltmeters of the Mt. Etna permanent tilt network.Taking account of the geometry and mechanism of the active tectonic structure obtained by seismological studies, the theoretical tilt linked to the faulting source was calculated at multiple different recording stations. It was found that the amount of measured deformation exceeded that which was generated seismically, indicating that much of the deformation along the fault was aseismic.The 9 January 2001 episode represents a shear response to a local stress caused by a volcanic source that acted in the period preceding the 2001 eruption. Tilt data also suggest a marked slip of 70-140 cm along the fault, probably due to the presence of fluids.

The 19Th Century

The modern seismic activation of the main oil and gas areas of the Pre-Carpathian foredeep – Dolyna (1974–1976), Nadvirna (1996–2013) and Boryslav (2014–2017) was traced. The refinement of the location of the studied earthquakes courses is carried out on the regional travel time tables and the method of residuals minimizing. The directions of ruptures breaking in the foci of the stronger ones were studied, the ruptures lengths and other parameters of these courses were estimated. The spatial models of seismic activity of the main seismogenic structures in these areas have been constructed. It has been established that most of the earthquakes courses tend to transverse faults of the anti-Carpathian (northeastern) direction (in the zones of their intersection with the Precarpathian deep fault), which cross or limit the oil and gas structures, part of the courses tend to the ones available here thrusts and folds of different depth. Taking into account the long-lasting (starting from the 19th century) active production of oil and gas condensate here the local seismicity, obviously, is additionally technogenically provoked (induced).
