Deformation History
There is data available for 1 deformation periods. Expand each entry for additional details.
Deformation during 1990 - 2003 [Subsidence; Observed by Leveling]
| Start Date: 1990 | Stop Date: 2003 | Direction: Subsidence | Method: Leveling |
| Magnitude: Unknown | Spatial Extent: Unknown | Latitude: Unknown | Longitude: Unknown |
|
Remarks: Leveling surveys reveal subsidence of the northern and southern flanks of the Mt. Epomeo resurgent block. The deformation is likely due to crack closure of the hydorthermal system. |

Vertical displacements recorded along the Coastline (blue), Borbonic line (green) and Casamicciola-Chiummano line (black) from 1990 to 2003. Numbers are the benchmarks. From: Sepe et al. 2007. |

Photo Gallery
| The Ischia volcanic complex forms a 6 x 9 km island at the western side of the Bay of Naples. The tip of the island of Procida, ENE of Ischia, is visible at the left in this Space Shuttle image. Tectonism has influenced volcanic activity at Ischia, and its high point (the dark-colored area at the center of the island) is a volcanic horst composed of ignimbrite deposits associated with Pleistocene caldera formation. During the Holocene, a series of pumiceous tephras, tuff rings, lava domes, and lava flows were erupted. NASA Space Shuttle image ISS002-E-8200, 2001 (http://eol.jsc.nasa.gov/). |

| DECADE Data | The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the MAGA Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO2 to the atmosphere, but installing CO2 monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere. |

WOVOdat
Single Volcano View Temporal Evolution of Unrest Side by Side Volcanoes |
WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore. |
| Large Eruptions of Ischia | Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA). |
| MIROVA | Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity. |
| MODVOLC Thermal Alerts | Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales. |
| EarthChem | EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS). |
