Abstract
Abstract We developed a new technique, Ice Box Calorimetry, for estimating heat discharge rates through steaming ground. Ice within an aluminum box provides a powerful tool for measuring the total heat transfer from the ground surface, including conductive heat, convective heat, and latent heat within vapor. Using this method, we are able to rapidly measure heat discharge rates without the need for specialized apparatus. Applying Ice Box Calorimetry to the Nishiyama steaming ground at Usu volcano, Japan in September 2006, we identified local variations in heat discharge rates. The total heat discharged from the entire geothermal area in September 2006 is estimated to be 27 MW, which represents just 1% of the rate immediately following an eruption from the volcano in 2000.

Summary
Thermal activities such as fumaroles and steaming grounds occur at many volcanoes during non-eruptive periods. We propose that ice in an aluminum box is a powerful tool in measuring the total heat transfers, including conductive heat, convective heat, and latent heat within vapor. Using this method, we are able to rapidly evaluate heatdischarge rates without the need for any specialized apparatus (Hochstein and Bromley, 2005). Where M (W/m2) is the heat required to melt the ice. To evaluate the total heat (i.e., Rn, C, and E), we placed a thermal insulation mat on the steaming ground surface and put an ice box upon the mat. To evaluate the total heat (i.e., Rn, C, and E), we placed a thermal insulation mat on the steaming ground surface and put an ice box upon the mat The results of the experiments demonstrate that the value of Qs estimated by IBC corresponds to the heat flows calculated from the power consumption of the hotplate
