Extended Data Fig. 7: Responses of discharges for different return intervals to tropical volcanic eruptions.
From: Global response of floods to tropical explosive volcanic eruptions

Percentages of streamgauges showing significant decreases (first and third columns) and increases (second and fourth columns) in peak discharges calculated for 2-, 10-, 50-, and 100-year return intervals. The darker the color, the greater the discharge return interval. The vertical red line indicates the season in which the eruption occurred. The shaded areas separated by different colors and vertical black lines represent each year, from the first (YR1) to the fourth year (YR4) after the eruption. Panels show results for Agung (Indonesia), Santa Maria (Guatemala), and Pinatubo (Philippines) eruptions.
