The main objective of this study is to assess the spatio-temporal dynamics land cover/land use changes in lower Mekong Delta over last 40 years with coastal Tran Van Thoi District Ca Mau Province, Vietnam as a case study. Land change are derived from moderate high spatial resolution (Landsat and SPOT) satellite imagery six time intervals ranging 1973 2011. Multi-temporal images were collected, georeferenced, classified using per-pixel method, validated, compared post classification for...
Abstract As space-based Earth observations are delivering a growing amount and variety of data, the potential this information to better support disaster risk management is coming into increased scrutiny. Disaster actions commonly divided different steps cycle, which include: prevention, minimize future losses; preparedness crisis management, often focused on saving lives; post-crisis aiming at re-establishing services supporting human activities. Based literature review examples studies in...
Abstract Classical mechanisms of volcanic eruptions mostly involve pressure buildup and magma ascent towards the surface 1 . Such processes produce geophysical geochemical signals that may be detected interpreted as eruption precursors 1–3 On 22 May 2021, Mount Nyiragongo (Democratic Republic Congo), an open-vent volcano with a persistent lava lake perched within its summit crater, shook up this interpretation by producing approximately six-hour-long flank without apparent precursors,...
The spatial distribution of eruptive vents around volcanoes can be complex and evolve as a volcano grows. Observations vent at contrasting volcanoes, from scoria cones to large shields, show that peripheral concentrate close the base. We use analogue experiments explore control load on magma ascent location. Results local loading stress field favors eruption rising away summit if central conduit is not established or blocked. Two sets scaled are developed with rheological properties analyze...
As a disaster prone country, Bangladesh is regularly hit by natural hazards, including devastating cyclones, such as in 1970, 1991 and 2007. Although the number of cyclones’ fatalities reduced from 0.3 million 1970 to few thousand or fewer recent events, loss lives impact on livelihoods remains concern. It depends meteorological characteristics cyclone general vulnerability capacity exposed population. In that perspective, spatially explicit risk assessment an essential step towards targeted...
The population of the semi-arid areas countries in East African Rift Valley (EARV) is faced with serious problems associated availability and quality drinking water. In these areas, water supply largely relies on groundwater characterised by elevated fluoride concentration (> 1.5 mg/L), resulting from interactions surrounding alkaline volcanic rocks. This geochemical anomaly often presence other naturally occurring potentially toxic elements (PTEs), such as As, Mo, U, V, which are known to...

Abstract. The inhabited zone of the Ugandan Rwenzori Mountains is affected by landslides, frequently causing loss life, damage to infrastructure and livelihood. This area ca. 1230 km2 characterized contrasting geomorphologic, climatic lithological patterns, resulting in different landslide types. In this study, spatial pattern susceptibility investigated based on an extensive field inventory constructed for five representative areas within region (153 km2) containing over 450 landslides. To...
Abstract. Natural disasters are too often presented as resulting from extreme natural phenomena affecting helpless populations, with people being insufficiently aware of the factors leading to and existing strategies mitigate their impacts. We developed a board game aimed at raising awareness about geohazards disaster risk reduction strategies. The target groups (1) secondary school students citizens (2) scientists stakeholders involved in management activities. For first group, aim is...
