Resumen:
1. INTRODUCTION
Lascar Volcano has been a constant study case due an its very high activity, reflected by
its high eruptive rate (2.5 and 0.8 eruptions/year considering eruptive plumes higher than 5,000 and
1,000 m above crater, respectively). Diverse efforts have been made it to understand its eruptive
behaviour, being only a very short eruptive period related to growthandcollapse dome between
19861994 characterized (Matthews et al., 1997). However, the eruptive behaviour before and
after of this period is not clear. Is considered that the understanding of process that trigger the
eruptions can help to determine the eruptive behaviour of a particular volcano, therefore, in this work
are presented field, satellite, air fall deposits and gas data from 20032005 eruptive period, with the
objective to characterize this eruptive period and to determine the process that have triggered the
eruptions.
