From: Vault-housed extensometers recorded a rapid initial pulse before precursory magma reservoir inflation related to the 2011 eruption of Shinmoe-dake, Japan

Strain changes in the directions of instruments E1–E3, 1–29 December 2009. Upper panel shows the original time series. Lower panel shows the detrended time series: the linear trend is estimated during the period 1–15 December 2009 and subtracted from all plotted data. The vertical green line indicates the onset of rapid inflation that we use to estimate the strain offset. The variations within the colored boxes in the detrended graph were used to estimate the magnitude and uncertainty of the strain offset. Daily precipitation at EBN is also shown (bar graph)
