A SPH Depth Integrated Model for Popocatepetl 2001 Lahar.

Lahars at volcanoes inundate surrounding areas and damage or destroy nearby communities. Unlike any other volcanic hazard, lahars do not require an eruption to occur. They can be triggered by bad weather or by edifice failure long after an eruption a timing that can worsen the hazard. Modeling of lahars has become an important tool in the assessment of the related hazards in order to undertake appropriate mitigation actions and reduce the associated risks.
