How often do geysers explode?
How often do geysers explode? In some small geysers, the eruption process can take just a few minutes. In larger geysers, it can take days. The most famous geyser in the United States, Yellowstone National Park's Old Faithful, erupts about every 50-100 minutes.
How do you know when a geyser is about to erupt?
It is impossible to predict the eruption time of most geysers because complex interactions take place between constantly changing factors. These include earthquakes, ongoing processes within underground channels, and fluctuations in a system's water or heat supply.
