@janinekrippner One model predicts that 10 to 50 cm of ash would blanket the metropolitan area. Gas turbines that generate power for Tokyo, rely on fresh-air intake and could be damaged or inoperable during an ashfall. 6/ https://t.co/P3yPt28q9h https://t

@janinekrippner Mount Fuji’s last confirmed eruption was in 1707-1708, when ash and cinders rained on nearby cities, including Edo/Tokyo. Is Tokyo at greater risk from ashfall, or earthquake-triggered debris avalanche? 5/ https://t.co/P3yPt28q9h https://t.
