DESCRIPTION:Speakers: Ramon Wyss (Royal Institute of Technology Stokolm Sw
 eden)\n\nPrior to the Kobe earthquake 1995\, a radon detector measuring in
  a mineclose to the epicenter\, observed a pronounced peak one week before
  the7.2 magnitude Hanshin earthquake that devastated the city of Kobe.Othe
 r measurements could conclude that the groundwater chemistry had changed b
 efore the earthquake. Recent measurements of the chemical composition of g
 roundwater in a borehole in Iceland show precursor phenomena. In this time
 span of 30 years\, we may ask ourselves why we have not come further. And 
 what would be a roadmap to move from forecasting to prediction? When it co
 mes to changes in radon concentration as a precursor phenomenon\,  a lite
 rature search will generate more than 800 references. In spite of the trem
 endous effort made to study radon at various sites\, there are no firm con
 clusions whether it can serve as a reliable precursor. The ArtEmis project
 \, that is funded by Euratom\, intends to clarify the longstanding topic o
 f radon as earthquake precursor and outlines a pathway how science can mov
 e from forecasting to prediction. The project outlines three essential ste
 ps in order to advance the field of earthquake forecasting by using geoche
 mical tracers like radon:1) the geographical coverage of the sensor system
  needs to be such\, that it is sensitive to different locations with a suf
 ficient granularity. This means that one needs many sensors along fault zo
 nes\, a massive sensor system. This will require that the sensor is cheap 
 and easy to deploy.2)radon concentration is subject to strong variations b
 ased on atmospheric changes like pressure\, temperature\, rain\, sun cycle
  and more. Hence\, the radon detector needs to be placed in groundwater\, 
 that provides stable pressure and temperature\, and that is shielded from 
 atmospheric influence to a large extent. The sensor can easily be equipped
  with additional instruments measuring temperature\, sound wave etc.3)the 
 radon signal from many sensors require advanced analysis\, where machine l
 earning algorithms and eventually AI will need to be employed to establish
  the correlation pattern with seismic movements.The speech will present Th
 e ArtEmis project that has developed a groundbreaking cheap sensor\, that 
 measures in real time with highestsensitivity. The sensor system and measu
 rements from the project in Greece and Switzerland will be presented. A ro
 ad towards expansion and future development will be discussed.\n\nhttps://
