US: Kilauea volcano erupts again in Hawaii

The USGS Hawaiian Volcano Observatory said it is elevating Kilauea's volcano alert level from advisory to warning and its aviation colour code from yellow to red as this eruption and associated hazards are evaluated. The USGS noted that high levels of volcanic gas -- primarily water vapour (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2) -- are the primary hazard of concern, as this hazard can have far-reaching effects down-wind.
