Short summary

This paper shows the results of secondary lahar modelling in Villa La Angostura town (Neuquén-Argentina) based on the Two-Phase-Titan modelling computer code. Possible occurrence of secondary lahars that could reach the city was analysed. The procedure allowed simulation of the path of flows from Florencia, Las Piedritas and Colorado creeks, which are the most influential streams in Villa La Angostura. The output of the modelling is a valuable tool for city planning and risk management.
