Every building that survives an earthquake owes its performance to the data captured the instant the ground moved. This eight-part series traces that journey — from sensor to structure — built for the next generation of engineers, seismologists, and geologists ready to work across the lines that usually separate these fields.

Oct 7

01 The Why: Defining Dynamic

Why do we need processed time series? Real-world applications in

building codes and risk analysis, and the fundamentals of time

history analysis for structural dynamics.

Oct 14

02 The Capture: Sourcing High-Quality Data

How strong-motion instrumentation networks operate in practice —

installation, a short history of the field, and the hardware criteria

behind high-quality recordings.

Oct 21

03 The Refinement: Cleaning the Raw Signal

The end-to-end ground motion processing workflow — filtering

techniques, data verification, signal modification, and how to choose

the right approach.

Oct 28

04 The Origin: Understanding the Source

How earthquake sources are defined and geology shapes ground

motion — source mechanics, tectonic regime, distance effects, and

near-field pulses, directivity, and fling step.

Nov 4

05 The Anatomy: Deconstructing the Waveform

Essential interpretation tools for ground motion — elastic response

spectra, Fourier amplitude spectra, and time-frequency methods

like wavelets and short-time Fourier transforms.

Nov 11

06 The Metric: Quantifying Destructive Potential

How intensity measures correlate with structural damage — PGA,

PGV, Arias Intensity, and significant-duration metrics (D5-95, D5-75).

Nov 18

07 The Orientation: Resolving Multi-Component Motion

The complexities of multi-dimensional ground motion — multicomponent

analysis, RotDxx orientation dependence, verticals, and

fault-normal/fault-parallel transforms.

Dec 9

08 The Synthesis: From Points to Performance

Tying it all together — integrating seismology, geology, and structural

engineering to carry a project from raw sensor data to a final

performance assessment.
