Volcán Isluga volcano is a broad stratovolcano in northern Chile 7 km west of the Bolivian border and forms the western end of a group of volcanoes extending to Tata Sabaya volcano in Bolivia. Isluga volcano is part of the 175,000 hectares Isluga National Park.
Isluga's summit contains a morphologically young, 400 m wide crater at the western end of the elongated, snow-covered summit region. Many lava flows with distinct levees can be seen on the southern flank and in 1878, lava flows destroyed several towns. At present, there is fumarolic activity at Isluga volcano, the last confirmed eruption was a small explosive eruption in 1913.

Background

Recent eruptions were phreatomagmatic and produced surges whose deposits can be found around the active crater. Holocene lava flows cover the northernmost ridge of the volcano.
An older glaciated dacite flow from the northwest side of the volcano has been dated at at 96,000 years. Lavas from Isluga overlie rocks from a dissected volcano (Quimsachatas) to the north and northeast, which erupted 566,000 years ago.

By Volcano Early Warning Preventive Isluga

L'Osservatorio del vulcano della meridionale delle Ande (OVDAS) appartenendo al servizio nazionale di geologia e miniere (SERNAGEOMIN) durante il mese di ottobre 2012 sono state installate due stazioni di monitoraggio e vulcanica monitoraggio vulcano Isluga, che ha registrato eventi sismici. Inoltre, abbiamo osservato la presenza di un'attività caratterizzata da un colore di gas fumarolici bianca colonna. Secondo i dati diffusi dalla guardia Enquelga CONAF e gli abitanti del villaggio hanno non stati sentiti o percepiti il rumore sismico, solo un odore di zolfo quando il boom si scende nella valle ha portata dal vento. ...
