Since the 1980 eruption of Mount St. Helens, volcanologists have made considerable progress toward predicting eruptions on the basis of precursors that typically start a few days to several months in advance. Although accurate eruption prediction is by no means routine, it may now be possible in some cases to extend the effective warning period by anticipating the onset of short‐term precursors. Three promising indicators of deep magmatic processes are (1) deep, long‐period earthquakes and… 

Long-and Short-Term Deformation Monitoring of Santorini Volcano: Unrest Evidence by DInSAR Analysis

Multi-reference Synthetic Aperture Radar (SAR) Interferometric techniques were applied to study the evolution of ground deformation during 1992-2011, with the use of ERS-1 and -2 and ENVISAT radar imagery to reveal the deformation history of Santorini Volcano.

Absence of Detectable Precursory Deformation and Velocity Variation Before the Large Dome Collapse of July 2015 at Volcán de Colima, Mexico

Improving the ability to foresee volcanic eruption is one of the main objectives of volcanologists. For this purpose, it is essential to better detect eruption forerunners and to understand their

Partly Cloudy With a Chance of Lava Flows: Forecasting Volcanic Eruptions in the Twenty‐First Century

A primary goal of volcanology is forecasting hazardous eruptive activity. Despite much progress over the last century, however, volcanoes still erupt with no detected precursors, lives and

Towards assimilation of deformation measurements in volcanology

Tracking magma emplacement at shallow depth as well as its migration towards the Earth's surface is crucial to forecast volcanic eruptions.With the recent advances in Interferometric Synthetic

Quantifying The Properties Of Magmatic Intrusions In The Central Andes With Geodesy

Volcanism in convergent arcs is the end result of magma ascending to the Earth’s surface. However, many of the details of the ascent process are still debated. In particular, how long does magma



Mechanism of the 1991 eruption of Hekla from continuous borehole strain monitoring

VOLCANOES erupt when the pressure in a magma chamber several kilometres below the edifice overcomes the strength of the intervening rock. Seismic activity may accompany and precede eruptions,

Intrusions of magma beneath volcanoes deform the surrounding rock and, if the intrusion is large enough, the overlying ground surface. Numerical models generally agree that, for most eruptions,

Spatiotemporal gravity changes at Miyakejima Volcano, Japan: Caldera collapse, explosive eruptions and magma movement

[1] Calderas are ubiquitous topographic features of volcanos, yet caldera formation itself has not been recorded intensively by modern measurement techniques. Here we report the spatiotemporal

Potential Hazards from Future Eruptions of Mount St. Helens Volcano, Washington

Mount St. Helens has been more active and more explosive during the last 4500 years than any other volcano in the conterminous United States. Eruptions of that period repeatedly formed domes, large

Preliminary Analyses of Volcanic Tremor Associated with 1992 Eruptions of Crater Peak, Mount Spurr Volcano, Alaska

The occurrence of volcanic tremor played an important role in monitoring and eruption forecasting at Mount Spurr by signifying changes in rates of precursory seismicity and indicating the beginnings

January 30, 1997 eruptive event on Kilauea Volcano, Hawaii, as monitored by continuous GPS

A continuous Global Positioning System (GPS) network on Kilauea Volcano captured the most recent fissure eruption in Kilauea's East Rift Zone (ERZ) in unprecedented spatial and temporal detail. The

Precursory changes in well water level prior to the March, 2000 eruption of Usu Volcano, Japan

The height of water levels in two wells located near Usu volcano, Japan, changed in a systematic fashion for several months prior to the eruption of Usu volcano on 31 March 2000. In one well,
