The third workshop of M3EF3 was held in Alicante, Spain, on November 16-17, 2017 (workshop website). The workshop was organized by the University of Alicante, Instituto Geologico y Minero de España, Grupo Español de trabajo en Subsidencia del Terreno, Group on Earth Observation (GEO), EU Feder and Spanish Ministery of Economy and Competitiveness and supported by University of Alicante, Cátedra de Movilidad Vectalia, Romanense de Mármoles S.L. About 35 people from 11 countries (China, Colombia, Egypt, Italy, Japan, Mexico, Packistan, Poland, Spain, The Netherlands, USA) attended the meeting.
The workshop was developed in two parts:
- on November 16th, a number of 12 talks have been given discussing the latest results in the field of monitoring, modelling and understanding the ground rupture mechanism (book of abstract);
- on November 17th, a field trip has been carried out in the Guadalentín Valley. This is the area presently characterized by the largest land subsidence due to aquifer overexpolitation in Europe (approx 10 cm/yr with a cumulative sinking of about 2.5 m over the last 3 decades) and the only region in the Europe affected by earth fissure possibly connencted to water pumping developed.
