METODOLOGIA SISMOLOGICA E ARCHITETTURA DATI

Metodologia Scientifica e Architettura di Telemetria

Come Earthquake.live acquisisce, valida, deduplica e analizza i dati sismici dalle reti di monitoraggio globali in tempo reale.

Acquisizione e Aggregazione Dati

Come vengono raccolti ed elaborati gli eventi sismici.

Earthquake.live acquisisce dati sismici in tempo reale dalle principali reti sismologiche mondiali:

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

Agenzia Meteorologica Giapponese

Feed ufficiali in tempo reale di JMA (bosai quake API) che coprono i terremoti nell'arcipelago giapponese e nel Pacifico nord-occidentale.

Normalizzazione dei Dati

Estrazione di parametri omogenei da molteplici agenzie di monitoraggio.

I feed grezzi arrivano in formati differenti. La nostra pipeline normalizza ogni evento in una struttura uniforme:

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.

Scale di Magnitudo e Rilascio di Energia

Comprendere le misurazioni sismiche logaritmiche.

Le magnitudo mostrate su Earthquake.live riflettono i calcoli degli istituti ufficiali (Magnitudo Momento Mw, Magnitudo Locale ML o Onde di 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.

Classificazione della Profondità Ipocentrale

Categorie di profondità e propagazione dello scuotimento in superficie.

< 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.

Qualità dei Dati e Avviso di Sicurezza

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.
