SEISMISCHE METHODIK & DATENARCHITEKTUR

Wissenschaftliche Methodik & Telemetriearchitektur

Wie Earthquake.live seismische Daten globaler Überwachungsnetzwerke in Echtzeit erfasst, validiert, dedupliziert und analysiert.

Datenerfassung & Aggregation

Wie Erdbebendaten abgerufen und verarbeitet werden.

Earthquake.live erfasst seismische Echtzeit-Feeds der weltweit führenden Netzwerke:

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

Japanische Meteorologische Behörde

Offizielle Echtzeit-Feeds der JMA (bosai quake API) für Erdbeben auf dem japanischen Archipel und im Nordwestpazifik.

Datennormalisierung

Einheitliche Parameter über verschiedene Meldebehörden hinweg.

Rohdaten treffen in unterschiedlichen Formaten ein. Unsere Pipeline normalisiert jedes Ereignis in einen strukturierten Datensatz:

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.

Magnitudenskalen & Energiefreisetzung

Verständnis logarithmischer seismischer Messungen.

Die auf Earthquake.live angezeigten Magnituden stammen direkt von den Messbehörden (überwiegend Momenten-Magnitude Mw, Lokalmagnitude ML oder Raumwellen-Magnitude 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.

Herdtiefenklassifizierung

Tiefenkategorien und ihre Auswirkung auf Erschütterungen an der Oberfläche.

< 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.

Datenqualität & Sicherheitshinweis

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.
