Scientists monitor Alaskan volcano

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, ...

Scientists monitoring Alaska's volcanoes have shut down stations that track eruptions in real time and put off repairing seismic equipment due to U.S. budget cuts—moves that could delay getting vital information ...

A U.K. budget airline will create an artificial volcanic ash cloud over Europe this summer to test ash detection technology. The experiment aims to avoid the kind of chaos that paralyzed air traffic during ...

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 ...

(Phys.org) —Giant landslides, lava flows and tectonic forces are behind this dynamic scene captured recently by ESA's Mars Express of a region scarred by the Solar System's largest volcano, Olympus Mons.

(Phys.org) —University of Auckland scientists have discovered that Rangitoto erupted not once or twice as previously believed, but multiple times over a period of 1,000 years, prompting a rethink of how Auckland volcanoes ...

(Phys.org) —In Antarctica in January, 2013 – the summer at the South Pole – scientists released 20 balloons, each eight stories tall, into the air to help answer an enduring space weather question: ...

Wind, humidity and rainfall combined precisely to create Monday's massive killer tornado in Oklahoma. The awesome amount of energy released dwarfed the power of the atomic bomb that leveled Hiroshima.

On May 20, 2013, NASA and NOAA satellites observed the system that generated severe weather in the south central United States and spawned the Moore, Okla., tornado.

Concerns continue to grow about the effects of climate change on fire. Wildfires are expected to increase 50 percent across the United States under a changing climate, over 100 percent in areas of the West by 2050 as projected ...

About 12,800 years ago when the Earth was warming and emerging from the last ice age, a dramatic and anomalous event occurred that abruptly reversed climatic conditions back to near-glacial state. According ...

Tornados, among the most violent of atmospheric storms, rarely reach the size and brutality of the twister that swept through an Oklahoma City suburb on Monday, experts say.
