Report prepared by the Hawaiian Volcano Observatory (HVO):
Lava returns to Pu‘u ‘Ō‘ō Crater
The presence of new lava in the bottom of Pu‘u ‘Ō‘ō crater was confirmed this afternoon by Hawaiian Volcano Observatory (HVO) scientists. When viewed at about 2 p.m. H.s.t., lava was covering fresh flows that may have erupted in the crater between 8 and 9 a.m. this morning, when first reported by local helicopter tour operators.
(略)
Lava was last seen at the Poupou ocean entry on June 20, after the intrusion that started on June 17, 2007, led to a small eruption by the morning of June 19. After a similar event in late January, 1997, lava returned to Pu‘u ‘Ō‘ō 23 days later and again flowed towards the ocean a few weeks after that.

私は火山の地質学が専門です。そのなかでも、噴火によって火山から吐き出される火山灰の分布に強い関心をもっています。福島第一原発から放出された放射能の分布は、火山灰に関する私の専門知識を応用してうまく理解することができます。
