About
There are indications that active volcanoes are more likely to erupt during periods of increased precipitation because the infiltrated rainwater weakens the rock. This website provides rainfall information for active volcanoes in order to asses how eruption likelihood may be affected by precipitation.
Methodology
This website displays satellite-derived precipitation information from the NASA/JAXA Tropical Rainfall Measurement Mission (TRMM) and the Global Precipitation Measurement missions starting in June 2000, together with eruption data of the Global Volcano Program (GVP). The precipitation data are shown and sorted in terms of 90-day rolling averages. Volcanoes sensitive to infiltrated precipitation can be recognized by eruptions occurring at days of elevated 90-day precipitation (dark green-shaded tertile). A publication is in preparation.
