Tilt changes (NS and EW components) and seismicity from tiltmeters in Kozukayama (KZY) and Kojiri (KZR). Timings of the initial swarm of the deep low-frequency event (DLF), blowout of the No. 39 SPW (BO) and the eruption are also shown. Seismicity here indicates hourly number of earthquakes within circles shown in Fig. 6. In KZY, seismicity and tilt change are evident in late-April to mid-May and on eruption days. In KZR, both increase in mid-May
