Using historical data, it may be inferred that critical situations for disaster events with a large number<br />
of victims occur with relatively high frequency every 10 to 30 years in the country due to climate events.<br />
A high intensity of rain can also affect other regions but, based on available evidence, the zones of San<br />
Vicente and Ilopango have greater exposure. Lahars of similar magnitude may be assumed to have a period<br />
of recurrence of nearly 50 years, and those that originated in San Vicente appear to have the greatest
