Fig. 14From: Phreatic eruptions at crater lakes: occurrence statistics and probabilistic hazard forecastRelative frequencies of observed lake temperature in comparison to pre-eruptive lake temperatures. Temperatures were measured irregularly. The baseline dataset includes a temperature for each day where data are available. The pre-eruption dataset includes the final temperature measured before each phreatic eruption as long as the measurement was less than 2 weeks before the eruptionBack to article page
