SEISMISCHE METHODOLOGIE & DATA-ARCHITECTUUR

Wetenschappelijke Methodologie & Telemetriearchitectuur

Hoe Earthquake.live seismische gegevens van wereldwijde bewakingsnetwerken in realtime verzamelt, valideert, ontdubbelt en analyseert.

Gegevensopname & Aggregatie

Hoe aardbevingsgegevens worden verzameld en verwerkt.

Earthquake.live verzamelt realtime seismische feeds van de belangrijkste seismologische netwerken ter wereld:

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

Meteorologisch Instituut van Japan

Officiële realtime feeds van JMA (bosai quake API) voor aardbevingen in de Japanse archipel en de noordwestelijke Stille Oceaan.

Gegevensnormalisatie

Consistente parameters extraheren uit meerdere meldingsinstanties.

Ruwe gegevens komen binnen in verschillende formaten. Onze pipeline normaliseert elke gebeurtenis:

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.

Magnitudeschalen & Energievrijgave

Logaritmische seismische metingen begrijpen.

De op Earthquake.live weergegeven magnitudes zijn berekend door officiële instanties (Momentmagnitude Mw, Lokale magnitude ML of Ruimtegolf 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.

Diepteclassificatie van het Hypocentrum

Dieptecategorieën en hun invloed op oppervlakteschokken.

< 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.

Gegevenskwaliteit & Veiligheidswaarschuwing

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.
