Those orange triangles are NASA FIRMS thermal detections, last 24 h. Brighter and larger = hotter. Detections, not confirmed wildfires.

What the marks mean
earthquake (USGS) · warmer = stronger
hazard alert (GDACS) · outlined glyph + word = type · red = Red alert
orange triangle · fire detection, last 24h (NASA FIRMS) — not a confirmed wildfire
cyan box · satellite-confirmed damage
red box · modelled worst-hit area, ranked by the number inside (USGS ShakeMap) — a model, not observation
banded box · hazard bands as published (GDACS) — no damage model
your registered site
faults (GEM) — context, not danger · structural type lives in the data
pulsing ring · M5.5+ shockwave, from orbit
risk lens · standing country score, not an event
place names orient you — they are not events
Area colour · how many people live there
fewer peoplemore people
A head count, not a danger scale — darker simply means more people.
Expected damage per block
Share of a 150 m block expected damaged — not a verdict on any one building.
1% or more of the block expected damaged
below 1% — a measured band, not an all-clear
Click a block for its exact expected share — six bands, anchored at MMI VI · VII · VIII · IX.
solid = observed
striped = modelled
red outline = block with a satellite-confirmed damaged building
painted = modelled, street level
cyan box = confirmed AOI
Imagery inside the boxes — Sentinel-1 radar change or a graded optical assessment, both proxies for damage, never a confirmed collapse. Modelled elsewhere. Nothing is drawn where neither has anything to say.
