Volcanoes cause climate gas concentrations to vary
Trace gases and aerosols are major factors influencing the climate. With the help of highly complex installations, such as MIPAS on board of the ENVISAT satellite, researchers try to better understand the processes in the upper atmosphere. Now, scientists have completed a comprehensive overview of sulfur dioxide measurements.

Landsat thermal sensor lights up from volcano's heat
As the Landsat Data Continuity Mission satellite flew over Indonesia's Flores Sea April 29, it captured an image of Paluweh volcano spewing ash into the air. The satellite's Operational Land Imager detected the white cloud of smoke and ash drifting northwest, over the green forests of the island and the blue waters of the tropical sea. The Thermal Infrared Sensor on LDCM picked up even more.

Canada's distinctive tuya volcanoes reveal glacial, palaeo-climate secrets
Deposits left by the eruption of a subglacial volcano, or tuya, 1.8 million years ago could hold the secret to more accurate palaeo-glacial and climate models, according to new research. The detailed mapping and sampling of the partially eroded Kima' Kho tuya in northern British Columbia, Canada, shows that the ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated.

No Redoubt: Volcanic eruption forecasting improved
Forecasting volcanic eruptions with success is heavily dependent on recognizing well-established patterns of pre-eruption unrest in the monitoring data. But in order to develop better monitoring procedures, it is also crucial to understand volcanic eruptions that deviate from these patterns. New research retrospectively documented and analyzed the period immediately preceding the 2009 eruption of the Redoubt volcano in Alaska, which was characterized by an abnormally long period of pre-eruption seismic activity that's normally associated with short-term warnings of eruption.

Scientists use islands to gauge rainfall's effect on landscapes
Researchers have used volcanic islands to measure how rainfall sets the pace of landscape formation.
