Brewing a Cup of Volcanic Tea

Many families along Iceland’s fertile southern coast can spin a good yarn about a close escape from an exploding volcano. Take Kristín Vogförð’s  grandfather, who was tending sheep on the eastern slopes of Katla when it erupted in 1918, melting glacial ice and violently flooding the rivers and fields below. According to an account by the geophysicist from the Icelandic Meteorological Office (IMO), he and the other shepherds rode their tough Icelandic horses through icy waters to safety. Unfortunately, his sheep were not so lucky.

In April, I joined a group of Icelandic volcano experts on a field trip to study rocks, gases and river runoff from Eyjafjallajökull. I witnessed modern escapes and came away impressed by how much Iceland’s scientists are doing to learn all they can from the latest eruptions, which have already begun to take a large toll on the small country’s tourism and agriculture industries.

Iceland Eruptions Fuel Interest in Volcanic Gas Monitoring

REYKJAVIK–As a brown cloud of ash drifts down from the slopes of Eyjafjallajökull toward their truck, Hanna Kaasalainen warns a colleague that their gas masks won’t be much good against carbon dioxide. The masks filter out poisonous gases released by magma such as sulfur dioxide, but carbon dioxide can simply displace oxygen in the air, asphyxiating the researchers as they take ash samples alongside a haze-enshrouded, deserted road. “We shouldn’t stay very long,” the University of Iceland geochemistry graduate student advises, before strapping on a bright yellow mask and opening the door.

Haitians go home as government proposes relocation

Almost as soon as the earthquake hit Haiti on 12 January, urban planners and scientists dusted off plans to relocate some of Port-Au-Prince’s infrastructure away from the crowded city centre, which is dangerously close to the Enriquillo fault.

In discussions with the Haitian government last month, geophysicists advocated relocating critical city infrastructure to the north (See: Haiti earthquake may have primed nearby faults for failure, Nature News). Now, at a United Nations donors’ meeting today, Haitian officials are due to present their Action Plan for National Recovery and Development, which incorporates recommendations to rebuild some of Port-au-Prince’s infrastructure in provincial towns further from the fault (New York Times).

At the same time, some Haitians have begun returning to their homes, or at least the lots where their homes once stood, encouraged by relief agencies keen to avoid flooded refugee camps during the upcoming rainy season (Associated Press).
