Deep magma transport at Kilauea volcano, Hawaii
The shallow part of Kilauea’s magma system is conceptually well-understood. Long-period and short-period (brittle-failure) earthquake swarms outline a near-vertical magma transport path beneath Kilauea’s summit to 20 km depth. A gravity high centered above the magma transport path demonstrates that Kilauea’s shallow magma system, established early in the volcano’s history, has remained fixed in...
متن کاملDeformation Due to Magma Movement and Ice Unloading at Katla Volcano, Iceland, Detected by Persistent Scatterer Insar
Katla volcano is situated in the south of Iceland, and is largely covered by the Mýrdalsjökull ice cap. Historically, Katla is one of the most active of Iceland’s volcanoes, with 20 eruptions in the last 1100 years, the last one being in 1918. The proximity of populated areas and international flight paths makes prediction of the timing and character of any future eruption particularly importan...
متن کاملRadiographic visualization of magma dynamics in an erupting volcano
Radiographic imaging of magma dynamics in a volcanic conduit provides detailed information about ascent and descent of magma, the magma flow rate, the conduit diameter and inflation and deflation of magma due to volatile expansion and release. Here we report the first radiographic observation of the ascent and descent of magma along a conduit utilizing atmospheric (cosmic ray) muons (muography)...
متن کاملTiming magma ascent at Popocatepetl Volcano , Mexico , 2000 ^ 2001
Magnetic anomalies may be used to constrain magma ascent and are useful as precursors to eruptions especially when correlated with other geophysical and geochemical data. In this paper we present multiparameter data on the magnetics, dome morphology, geochemistry and seismicity associated with the December 2000^January 2001 eruptions, the largest of the recent eruptions at Popocatepetl Volcano....
متن کاملForecasting magma-chamber rupture at Santorini volcano, Greece
How much magma needs to be added to a shallow magma chamber to cause rupture, dyke injection, and a potential eruption? Models that yield reliable answers to this question are needed in order to facilitate eruption forecasting. Development of a long-lived shallow magma chamber requires periodic influx of magmas from a parental body at depth. This redistribution process does not necessarily caus...
