  3. 2. Wisdom-volkano : a novel tool based on open GIS and time-series to analyse and share volcanic data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Fulgencio Sanmartín; [2016]
    Keywords : GIS; volcanic eruption; interferogram; time-series; seismology; GNSS; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Abstract : Active volcanoes threaten life around. In order to predict their eruptions earlier and mitigate their hazards, several variables must be observed and compared. Geographical information systems (GIS) combine different geospatial images from remote or local sensing. However, GIS often miss how maps change during the time. READ MORE

  4. 3. Monitoring of Santorini (Greece) volcano during post-unrest period (2014-2016) with Interferometric Time series of Sentinel-1A

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Christos Bountzouklis; [2016]
    Keywords : Santorini Volcanic Complex; earth observation; volcanic hazard; SAR Interferometry; Sentinel-1A; physical geography and ecosystem science; Earth and Environmental Sciences;

    Abstract : Ground deformation monitoring is one of the main geoindicators that should be considered to assess volcanic hazard. Satellite earth observation data and Synthetic Aperture Radar (SAR) interferometry have been used continuously since 1992 to measure or study the temporal evolution of surface deformation in volcanic areas in conjunction with ground-based geodetic measurements.

  5. 4. Magmatic Sheet Intrusions as Seen in Surface Deformation - Developing a Tool for Interpreting Volcanic Unrest

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frank Guldstrand; [2015]
    Keywords : Analogue modelling; surface deformation; cone sheets; dykes; moiré; photogrammetry; sheet intrusions; propagation; Analog modellering; ytdeformation; inverterade koner; vertikala plan; moiré; fotogrammetri; magmatiska intrusioner; propagering;

    Abstract : The end-member types of shallow magmatic intrusions comprise cone sheets and dykes. These propagate from their source magma chamber towards the Earth’s surface. The propagation of magma within the shallow part of the volcano plumbing system produces surface deformation and seismicity, signs of volcanic unrest. READ MORE

  6. 5. Wireless sensor network for volcano monitoring

    University essay from KTH/Mikroelektronik och Informationsteknik, IMIT

    Author : Yan Zhang; [2005]
    Keywords : wireless sensor network; volcano; remote; sensing; trådlös sensor nätverk; vulkan; fjärranalys; 关键i可: 无线传感器网络; 火山; 远程， 传感; trådlös sensor nätverk; vulkan; fjärranalys;

    Abstract : The monitoring of volcanoes for risk assessment has deployed single sensors for years. This kind of system requires manual supervision to monitor each sensor, which makes the monitoring work not flexible and efficient enough to adapt to variable volcano environments. READ MORE
