Guides
Understand building seismic monitoring
Clear, evidence-based explanations for residents, building managers, small organizations, and technical readers. These guides explain what monitoring data can show, what it cannot prove, and when qualified engineering review is still required.
Start with practical questions
Building Seismic Monitoring Device: What It Measures
Learn what a fixed building seismic monitoring device measures, how it differs from a phone app or alarm, and when installation adds value for residents and managers.
Measuring Building Motion After an Earthquake
Understand how post-earthquake building motion is measured, what acceleration and time history data show, and when the results support engineering review.
Earthquake App vs Fixed Building Sensor: Key Differences
Compare earthquake apps and fixed building sensors to understand what each does well, when a fixed reference matters, and how alerts differ from building records.
Seismic Sensor Placement in Buildings: Mounting and Planning
Learn how to approach seismic sensor placement in buildings, including stable mounting, single-sensor vs array decisions, and a practical pre-installation checklist.
Explore the measurement concepts
MEMS Accelerometers for Seismic Monitoring: Key Concepts
Understand how MEMS accelerometers work in seismic monitoring, including resolution, range, noise, sampling, timing, and what makes low-cost sensing useful data.
Building Natural Frequency Monitoring: What Changes Mean
Learn what natural frequency means for buildings, how ambient vibration and strong motion reveal it, why frequency varies, and when trend monitoring is useful.
