Hi PHIVOLCS team,
May I request the formal definitions of your classification of Ground Rupture, Ground Shaking, Earthquake-Induced Landslide, Liquefaction, Tsunami and which of these are considered dangerous/ safe levels? This information was taken from Hazard Hunter wherein barangays were classified with these tags.
Example:
1) Liquefaction
a. Generally Susceptible (Safe/ Dangerous) ?
b. High Potential (Safe/ Dangerous) ?
c. Highly Susceptible (Safe/ Dangerous) ?
d. Least Susceptible (Safe/ Dangerous) ?
etc.
2) Tsunami
a) Inundation depth: <1m (Safe/ Dangerous) ?
b) ...
etc.
Thank you!
