Volcanic Ash Fall

Russell Cameron writes,

Volcanic ash was observed and collected by Allan Brandell in Nelson Lagoon on March 28, 2016. Brandell collected and shipped the ash sample to the Alaska Volcano Observatory who confirmed it was volcanic ash from Mt Pavlof.

LEO says:

The following information was taken from the Alaska Volcano Observatory (AVO)

Volcanic ash consists of tiny jagged pieces of rock and glass. Ash is hard, abrasive, mildly corrosive, conducts electricity when wet, and does not dissolve in water. Ash is spread over broad areas by wind. Short-term effects commonly include irritation of the eyes and upper airways and exacerbation of pre-existing respiratory disease such as asthma; serious health problems are rare. In addition, affected communities may experience increased levels of psychological distress. This is particularly the case when eruptions cause social and economic disruption.

People should avoid unnecessary exposure to ash and wear an effective face mask when outside to reduce inhalation of ash particles. People with existing respiratory problems should take special care to avoid exposure to airborne ash and should carry their medication with them.

Medical services can expect an increased number of patients with respiratory and eye symptoms during and after ashfall. People will generally be very concerned about the effects of ash, and questions commonly arise about the characteristics of the ash and the implications for their health
