METODOLOGIA SISMOLÓGICA E ARQUITETURA DE DADOS

Metodologia Científica e Arquitetura de Telemetria

Como o Earthquake.live ingere, valida, deduplica e analisa dados sísmicos de redes de monitoramento globais em tempo real.

Ingestão e Agregação de Dados

Como os registros sísmicos são coletados e processados.

O Earthquake.live ingere dados sísmicos em tempo real das principais redes sismológicas mundiais:

USGS

United States Geological Survey

Continuous global GeoJSON feeds updated every minute, providing comprehensive global coverage and high-precision North American telemetry.

EMSC

Euro-Mediterranean Seismological Centre

European, Mediterranean, and global real-time event feeds providing rapid regional event verification and magnitude data.

JMA

Agência Meteorológica do Japão

Feeds oficiais em tempo real da JMA (bosai quake API) cobrindo terremotos no arquipélago japonês e noroeste do Pacífico.

Normalização de Dados

Extração de parâmetros consistentes entre múltiplas agências.

Os dados brutos chegam em diversos formatos. Nossa pipeline padroniza cada evento em um registro estruturado:

MAGNITUDERounded to 1 decimal place with source scale preservation (Mw, ML, mb).

COORDINATESWGS84 Latitude and Longitude decimal degrees.

FOCAL DEPTHCalculated in kilometers below the surface (absolute positive depth).

UTC TIMESTAMPExact event origin time and latest upstream update timestamp.

Escalas de Magnitude e Liberação de Energia

Compreendendo medições sísmicas logarítmicas.

As magnitudes exibidas no Earthquake.live são calculadas pelas agências oficiais (Magnitude de Momento Mw, Magnitude Local ML ou Ondas de Volume mb).

Gutenberg-Richter Energy Relationlog₁₀(E) = 4.8 + 1.5 · M

Earthquake magnitude is logarithmic. Each whole unit step on the magnitude scale (+1.0) corresponds to approximately a 31.6× increase in released seismic energy and a 10× increase in ground motion amplitude:

MagnitudeClassificationEnergy Comparison

M 3.0 – 3.9

Minor

Often felt indoors, rarely causes damage.

M 4.0 – 4.9

Light

Noticeable shaking of items; minimal structural risk.

M 5.0 – 5.9

Moderate

~31.6× more energy than M4. Can cause damage to weak buildings.

M 6.0 – 6.9

Strong

~1,000× more energy than M4. Destructive across populated areas.

M 7.0+

Major / Great

~31,600× more energy than M4. Severe, widespread regional disaster.

Classificação de Profundidade Focal

Categorias de profundidade e sua relação com o abalo na superfície.

< 70 km • Shallow

Highest shaking intensity at the surface. Less rock dampening between the rupture point and surface infrastructure.

70 – 300 km • Intermediate

Wider felt radius with lower peak ground acceleration at the epicenter due to crustal energy dissipation.

> 300 km • Deep

Originates in deep subduction slabs. Energy is widely dispersed, producing mild shaking over large continental areas.

Qualidade dos Dados e Aviso de Segurança

Earthquake magnitudes and locations displayed immediately after an event are preliminary automated estimates published by monitoring agencies (USGS / EMSC / JMA) and are subject to revision as duty seismologists review station data.

Earthquake.live is an informational monitoring tool. In emergency situations, always follow official instructions from your local civil protection and emergency management authorities.
