Magma: What’s hot and what’s not

| | Nov 9 2017 - 3:40pm | Comments

Scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory routinely collect lava samples from Kilauea and use the chemistry of these samples to infer the temperature of magma (molten rock below Earth’s surface).

    Hawaii’s mid-Pacific location makes it an excellent meeting ground for globally dispersed collaborators of all kinds. For the next two weeks, the U.S. Geological Survey’s Hawaiian Volcano Observatory will host scientists from New Zealand and Alaska who are funded in part by a joint U.S.-New Zealand Commission on Science and Technology Cooperation. The commission supports international partnerships to co-develop advances in research, science and technology. The scientists are here to focus on the impacts of three important and globally-relevant volcanic hazards: volcanic ash, volcanic gas and lava flows.

    Exploration of volcanoes within our solar system has been much like the exploration of Hawaiian volcanoes in the 19th century: sporadic. We now know where most of the volcanoes beyond Earth are, but know little about how they work. But bits of information are being collected, and whether they are from Earth-based observations, satellite imagery, or fly-by missions, every piece is important, because our best understanding will come from compiling all available data from every source.
