Goals and development of the Alaska Volcano Observatory Seismic Network and application to forecasting and detecting volcanic eruptions Goals and development of the Alaska Volcano Observatory Seismic Network and application to forecasting and detecting volcanic eruptions
The Alaska Volcano Observatory (AVO) seismic network has been in operation since 1988 and during this time has grown from 29 to 217 seismic stations providing real-time monitoring of 32 active volcanoes in Alaska, as well as useful data for regional earthquake monitoring. Since 1988, AVO has detected 59 volcanic eruptions at Aleutian arc volcanoes, and 31 of these have been captured by...

Distinguishing high surf from volcanic long-period earthquakes Distinguishing high surf from volcanic long-period earthquakes
Repeating long-period (LP) earthquakes are observed at active volcanoes worldwide and are typically attributed to unsteady pressure fluctuations associated with fluid migration through the volcanic plumbing system. Nonvolcanic sources of LP signals include ice movement and glacial outburst floods, and the waveform characteristics and frequency content of these events often make them...

Earthquake studies reveal the magmatic plumbing system of the Katmai volcanoes Earthquake studies reveal the magmatic plumbing system of the Katmai volcanoes
The 1912 eruption of Novarupta was the largest of the 1900s (Fierstein and Hildreth 2001, Hildreth et al. 2003). A century later, fundamental questions remain regarding the source of the magma for that eruption. A previous seismic study of the Katmai area (Jolly et al. 2007) identified a single large area of anomalous structure in the subsurface centered beneath Katmai Pass (Figure 2)...

Late 20th century increase in South Pole snow accumulation Late 20th century increase in South Pole snow accumulation
A compilation of the 37-year history of net accumulation at the South Pole [Mosley-Thompson et al., 1995] suggests an increase in net annual accumulation since 1965. This record is sporadic and its quality is compromised by spatially restricted observations and nonsystematic measurement procedures. Results from a new, spatially extensive network of 236 accumulation poles document that...
