4. Satoshi Matsumoto, Hiroshi Shimizu, TAKESHI MATSUSHIMA, Kenji Uehira, Yusuke Yamashita, Manami Nakamoto, Masahiro Miyazaki, Hiromi Chikura, Short-term spatial change in a volcanic tremor source　during the 2011 Kirishima eruption, Earth, Planets and Space, 65, 323-329, 2013.05, Volcanic tremors are indicators of magmatic behavior, which is strongly related to volcanic eruptions and
activity. Detection of spatial and temporal variations in the source location is important for understanding the
mechanism of volcanic eruptions. However, short-term temporal variations within a tremor event have not always
been detected by seismic array observations around volcanoes. Here, we show that volcanic tremor sources were
activated at both the top (i.e., the crater) and the lower end of the conduit, by analyzing seismograms from a
dense seismic array 3 km from the Shinmoedake crater, Kirishima volcano, Japan. We observed changes in the
seismic ray direction during a volcanic tremor sequence, and inferred two major sources of the tremor from the
slowness vectors of the approaching waves. One was located in a shallow region beneath the Shinmoedake crater.
The other was found in a direction N30◦W from the array, pointing to a location above a pressure source. The
fine spatial and temporal characteristics of volcanic tremors suggest an interaction between deep and shallow
conduits..
