31 Hazard Warning Sign Pictograms

I am putting together a unified set of natural-hazard warning icons and need them rendered in the visual language of standard road signs: a red equilateral triangle, white interior, and a solid-black pictogram centered within. The style must stay simple and minimalistic—no gradients, outlines, or text labels—so the warnings remain instantly readable even at very small sizes.

Artwork requirements
• Canvas: 128 × 128 px, background outside the triangle fully transparent.
• Consistency: every triangle identical in size and position across all 31 files.
• Symbol colour: solid black on white interior (use #000000).
• Scale: supply an exact 64 × 64 px version of each sign that still looks sharp.
• Extra set: one additional 64 × 64 batch rendered entirely in a single colour (monochrome).
• Extra set: one additional 128 × 128 SVG batch rendered entirely in a single colour (monochrome).
• Format: deliver everything as lossless PNG + the extra SVG.

Hazards to illustrate (one pictogram each)
Avalanches, Blizzards, Droughts, Dust storms, Earthquakes, Extreme winter weather, Floods, Fog, Forest fires, Frost, Hailstorms, Haze, Hurricanes, Icebergs, Land subsidence, Landslides, Large waves, Locust plagues, Mudslides, Permafrost, Reef, Rockslides, Sandstorms, Sea ice, Sea-level rise, Severe storms, Ship icing, Thunderstorms, Tidal hazards, Tornadoes, Tropical cyclones.

Acceptance
I will check that each icon aligns perfectly with the template triangle, scales cleanly, and is visually distinct from the others at 64 px. Once approved, please provide the three complete PNG bundles (128 px colour, 64 px colour, 64 px monochrome) in neatly labelled folders or a single zip.

NOTE:
I tried using AI, which worked to some extent - placing was wrong and some pictograms became overcomplicated. Included insipirational files, but I don't need a 1:1 copy for included - some are over complicated and needs to be more simple, and remember they should be distingusiable when placed on a row in monochrome.
