Amongst natural catastrophes, earthquakes represent about one fifth of the economic losses, and are responsible for an average of 20 thousand fatalitie…
The demonstrated early warning capability of Global Navigation Satellite Systems (GNSS) to accurately, rapidly, and cost effectively measure deformation of the Earth’s surface and the response of the ionosphere to this deformation was the factual basis for the GNSS Tsunami Early Warning Systems Workshop (GTEWS) and this report. GTEWS 2017 was held in Se…
Sentinel Asia (SA) was conceptualized in 2005 and first began operation in 2007. SA is engaged in activities to share and provide disaster-related information including earth observation satellite images via the internet to contribute to disaster management in the Asia-Pacific region. Between 2006 and 2016, 270 emergency observation requests were made o…
Landslides can assume catastrophic and disastrous proportions causing immeasurable damage to life and property, and are one of the costliest natural hazards. In South Africa, despite significant strides made towards consolidating data on geohazards in the country, very few studies on mass movement have been documented.
