Fig. 10From: Analyzing the continuous volcanic tremors detected during the 2015 phreatic eruption of the Hakone volcanoAn exponential model and a power scaling model for the duration-amplitude distribution of the volcanic tremor. The red lines in the diagrams are the least-squares fit of the exponential and power law models. R 2 is the correlation coefficient of the linear regression for both models, and λ −1 is the characteristic amplitude of the distributionBack to article page
