  2. Challenges and topic for discussions • Communication and dissemination • Some regions do nothing in case of yellow level, neither send forward to municipalities • Others complain of too many yellow and do not like to have 2 separate warning (flood and landslides) • Some municipalities wish to receive directly warnings and not through regions • What to do in the different levels? Authorities start to act only when is red level (not everybody understand that in yellow and orange level damages can occur). • Lack of emergency plans and risk maps (identifying critical areas) • Communication (experts and population) • Avoid too many false alarm, wrong level: yellow  orange • Toomanyleaders/politiciansbetweenexperts and population/localauthorities (developingcountriesvsdevelopedcountries)

  3. Eventscenarios Riskscenarios INTERVENTION MODEL Levels of criticality Levels of alert

  4. Eventscenarios • Landslide velocity • Landslide surface • Landslide scarp • Landslide volume • Thickness • Magnitude • Involved material • Occurrence probability Geometric index Properties of expected phenomena

  5. LANDSLIDE VELOCITY (VEL)

  6. LANDSLIDE SURFACE (SUR) • LANDSLIDE SCARP (SCA)

  7. LANDSLIDE VOLUME (VOL) • THICKNESS (THI)

  8. GEOMETRIC INDEX (GEI)

  9. MAGNITUDE (MAG) • f(GEI, VEL)

  10. INVOLVED • MATERIAL (IM) • OCCURRENCE • PROBABILITY (PRO)

  11. MAP OF EVENT SCENARIOS – level 1 • Perimeter of landslide and propagation zone MAG1 MAG3 MAG2

  12. MAP OF EVENT SCENARIOS – level 2 Normalized value Mud Debris Earth GEI PRO VEL MAG Mixture of components

  17. Riskscenarios • Mud and/or debris movements which could induce a friction reduction and facilitate slips

  18. Riskscenarios • Road subsidence induced by landslides that could drag or drop vehicles

  19. Riskscenarios Falls of significant volumes and/or boulders that could crush or cover vehicles and constitute an obstacle for others vehicles

Levels of criticality and alert • 4 states: • state 0 (S0) = no variation • state 1 (S1) = small variation • state 2 (S2) = moderate variation • state 3 (S3) = high variation SEN Sensors Model outputs CAED • 2 states: • state 0 (S0) = no variation or not significant • state 1 (S1) = significantvariation IND INDICATORs • Meteorologicaland hydrologicalmodels for vaste areas (for exampleFLaIR model)
