12Deep-focus quakes (>300km) rarely exceed M8.0 due to rock plasticity at depth

Verified

13Intermediate-depth quakes (70-300km) comprise 15% of global events, often M6-7.5

Verified

14Shallow quakes (<70km) account for 85% of events and most damage due to proximity

Single source

15The energy-magnitude relation is log10(E) = 4.8 + 1.5M, where E in joules

Verified

16Magnitude 4.0 quakes are felt locally, equivalent to 11 tons TNT

Verified

17Historical quakes like 1556 China M8 estimated 830,000 deaths, highest toll ever

Verified

18Modern instruments cap at M10 theoretically, but Earth's faults limit to ~M9.6 max

19Body-wave magnitude (Mb) used for teleseismic events, sensitive to P-waves

Verified

20Surface-wave magnitude (Ms) best for 20-150km depths, M6-8 range

Magnitude Statistics Interpretation

An earthquake's magnitude whispers its power logarithmically, where a mere whole number leap unleashes 31 times the energy, so while humanity measures its might in Hiroshima bombs, Earth casually tosses out thousands of them in a single, record-breaking shrug.

Preparedness and Response Interpretation

From California’s code-enforced bedrock to Japan’s towering refuges, our global tapestry of drills, data, and dogged preparation weaves a net under the shaking world, proving that while we cannot stop the Earth’s rumble, we can choose not to crumble with it.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source

ChatGPT

Claude

Gemini

Perplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional

ChatGPT

Claude

Gemini

Perplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified

ChatGPT

Claude

Gemini

Perplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
