Fish in Oahu
A welcome break from the AOGS Conference, at only a 20-minute drive from Honolulu: the Hanauma Bay Nature Preserve, a fish paradise within an ancient volcano caldera.

Kilauea lava rivers and laze
Laze rising to the sky. Laze, a combination of the words lava and haze, is the product of a chemical reaction that happens when molten, 1200 degree Celsius lava hits the ocean. The sea water gets boiled, creating a potentially deadly mix of hydrochloric acid, steam, and tiny volcanic glass particles. The lava rivers covered a distance of 10 km from the fissure to the coast.
