  1. 1. Property Prices and Disaster (In)Justice: Fifty Years of Demographic Change in Hawai’i County’s Lava Hazard Zones

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : AnaCapri Mauro; [2022]
    Keywords : Social Vulnerability; Volcanic Hazards; Disaster Justice; Risk Governance; Temporal Analysis; Mauna Loa; Kīlauea; Social Sciences;

    Abstract : While there is a degree of homogeneity in the physical impact that volcanic hazards can cause, the experience of volcanic risk and the politics of exposure are far from equal. The purpose of this thesis is to expand on research citing population growth and property price dynamics as factors encouraging settlement in the Mauna Loa and Kīlauea lava hazard zones. READ MORE

  3. 2. Constraining the duration of eruptions of the Rangitoto volcano, New Zealand, using paleomagnetism

    University essay from Lunds universitet/Geologiska institutionen

    Author : Linda Aulin; [2017]
    Keywords : Rangitoto; paleomagnetism; paleointensity experiments; Auckland volcanic field; thermal demagnetization; Earth and Environmental Sciences;

    Abstract : The volcano Rangitoto belongs to the Auckland volcanic field and is situated north east of Auckland city, New Zealand. The volcanos of the Auckland volcanic field have previously thought to be of monogenetic origin, but recent studies indicate that Rangitoto has a long history of eruptions, which would suggest that the volcanic system may have entered a new phase.

  4. 3. 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

  5. 4. Basalt and Andesite Magma Storage and Evolution in Puyehue Volcano (40.5 °S), Chile

    University essay from

    Author : Joaquim Otero; [2013]
    Keywords : Volcano; Thermobarometry; Puyehue; Basalt; Andesite; Contamination;

    Abstract : The study of magmatic processes and their location in the crustal profile is fundamental for the understanding of the volcanic systems and their associated hazards. Changes and continuities in magma storage zones, fractional crystallization and crustal contamination are studied over a time span of 300 ka in Puyehue Volcano in the Southern Volcanic Zone, Chile.
