Except for the geysers, which emit hot water, and mud volcanoes whose subject, largely organic, comes from hydrocarbon deposits relatively close to the surface, eruptions are due to terrestrial volcanoes.

In the century that elapsed from the year 1900, there were about one or two disasters for decades, ocuasionados by natural phenomena which have occurred in the decline of national development.
According to historical records, the number of events occurring in this century equivalent tothe occurrence of a daily event for 10 years. This has been one of the findings revealed by this study.

Earthquakes related in some cases, the activity of the volcanic chain in the country, and others, recorded majorevents outside the Salvadoran border were classified as some of the events that have affected the dynamics of destructive phenomena of nature on the Salvadoran soil.
From 1910 to 1920 the sources of information for disaster Register here increases the emergence of the newspaper "La Prensa". Importantly, for the first 4 years (1910-1914) survey information for thecompilation of this chips was conducted primarily from local newspapers, memoirs, monographs, books and documents available in the general archives of the nation. The reason for this is that is not conserved in any documentation center commercial newspapers these years.
