recorded and recovered, although heavily damaged and warped (the video ends when the cameraman notices a sound apparently associated with the generating pyroclastic flow, and asks "What's that sound?", whilst turning the camera in the direction of Mt. Fugen). This video was broadcast on October 16, 2005, and is now exhibited at the Unzendake Disaster Memorial Hall (Shimabara City) alongside the melted camera. It is unclear as to what caused the unprecedented size of the second, large-scale pyroclastic flow on June 3. It has been suggested that the heavy ash-laden column that towered over the main flow, collapsed during its descent, causing the surge. It has also been pointed out that when the dome collapsed, 0.5 million cubic meters of hardened lava broke off, leaving a significant collapse scar afterwards, suggesting that the size of the dome collapse (rather than the column collapse) initiated the surge. Other explanations account the fact that previous lahars and pyroclastic flows filled the Mizunashi Valley, raising the level of the river-bed and making it more likely for the flow to "skip" ridges that would have once stopped it. According to the 2011 documentary (French for Facing the Killer Volcano), the unexpected surge could have been caused by phreatic explosions as the main body of the pyroclastic flow proceeded down two waterfalls at the headwaters of the river, fragmenting the ash-particles of the avalanche and expanding the energy of the overlaying gas and ash cloud. Effects and aftermath Pyroclastic flows continued over the next few days following the June 3 eruption, however, they were reportedly smaller and less frequent. Even so, rescue efforts and movements to recover the bodies of the victims, were disrupted and stalled due to the ever-present danger. Authorities eventually managed to recover 27 bodies and brought them to the Anyoji Temple. 4 of the victims' bodies were never recovered, and were reported as missing at the time, but presumed dead. Many of the recovered bodies were carbonized due to the extreme heat of the surge, and were identified by either dental records, or personal belongings they carried with them (e.g. wristwatches or cameras). 17 victims on the outer edges of the affected zone lived for a while, before succumbing later to their injuries (burns to their skin and lungs, or inhaled ash in their windpipe and lungs). The final victim reportedly died on August 8. The collapse of the lava dome
