METODOLOGI SEISMOLOGI & ARSITEKTUR DATA

Metodologi Ilmiah & Arsitektur Telemetri

Bagaimana Earthquake.live mengumpulkan, memvalidasi, melakukan deduplikasi, dan menganalisis data seismik dari jaringan pemantauan global secara real-time.

Pengumpulan & Agregasi Data

Bagaimana data gempa bumi diambil dan diproses.

Earthquake.live mengumpulkan data seismik real-time dari jaringan seismologi utama dunia:

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

Badan Meteorologi Jepang

Feed resmi real-time dari JMA (bosai quake API) yang mencakup gempa bumi di kepulauan Jepang dan Pasifik barat laut.

Normalisasi Data

Mengekstrak parameter yang konsisten dari berbagai lembaga pemantau.

Data mentah masuk dalam berbagai format. Pipeline kami menormalisasi setiap peristiwa menjadi data terstruktur:

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.

Skala Magnitudo & Pelepasan Energi

Memahami pengukuran seismik logaritmik.

Magnitudo yang ditampilkan di Earthquake.live merupakan nilai yang dihitung oleh lembaga resmi (Magnitudo Momen Mw, Magnitudo Lokal ML, atau Gelombang Bodi 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.

Klasifikasi Kedalaman Fokus

Kategori kedalaman dan hubungannya dengan guncangan permukaan.

< 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.

Kualitas Data & Pemberitahuan Keselamatan

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.
