Frequently Asked Questions

What is the difference between the 3-ton and 5-ton shake tables?

The main difference is payload. QuakeLogic's 3-ton shake table is sized for medium-scale specimens up to 3 tons, while the 5-ton model accommodates larger structures and components up to 5 tons. Both operate across a frequency range suited to simulating a wide variety of seismic waves, use precise repeatable motion control, are IP-based, and include the same EASYTEST Windows control software free of charge.

What does IP-based shake table technology mean?

An IP-based shake table communicates with its controller and the laboratory network over standard Internet Protocol rather than proprietary cabling. In practice that means the table can be configured, run and monitored from a networked PC, test data can be stored on existing IT infrastructure, and the system integrates with other networked instruments in the lab without special interface hardware.

What software controls QuakeLogic shake tables?

QuakeLogic shake tables are controlled by EASYTEST, a Windows-based control software supplied free with every table. EASYTEST provides the interface for configuring test profiles, executing runs on the 3-ton, 5-ton and other models, and analyzing recorded data afterward. Because the same software is used across the product line, operators who learn it on one table can run any other QuakeLogic table.

What can a 3-ton or 5-ton shake table be used to test?

A 3-ton or 5-ton shake table is used for structural testing of scaled buildings, bridge components and other structures under simulated earthquakes; component testing of joints, connectors and materials against seismic safety standards; university teaching and research; and product development, where manufacturers validate equipment that must withstand seismic forces before certification.

Which shake table size should a university lab choose?

Choose based on the heaviest specimen you expect to test, with margin for fixtures. A 3-ton table covers most medium-scale structural models and component tests at lower cost and footprint; a 5-ton table is justified when larger assemblies or full-scale components are planned. Both are IP-based and ship with EASYTEST, so the decision is driven by payload and lab space rather than control capability.

Usage Scenario

Scautopick is typically used in an automated seismic monitoring setup where continuous real-time data needs to be processed to detect and locate seismic events quickly. It significantly speeds up the detection process by minimizing the need for manual picks.

Summary of Differences

  • Functionality:
  • Scolv: A GUI tool for manual review, analysis, and event location.
  • Scautopick: An automated tool for real-time phase picking from continuous data streams.
  • User Interaction:
  • Scolv: Requires manual interaction and is used for detailed event analysis and quality control.
  • Scautopick: Operates automatically with minimal human intervention.
  • Use Case:
  • Scolv: Used for refining and confirming events, providing detailed analysis tools for seismologists.

Key Takeaways

  • scautopick automatically picks P and S wave arrivals from continuous data with no human intervention, suited to early warning.
  • scolv is a GUI for manual phase picking, event relocation, magnitude calculation and error estimation.
  • scautopick feeds automatic picks to scanloc and other modules for automatic event location.
  • scolv output is a refined, verified event catalog; scautopick output is raw phase picks.
  • Typical workflow: scautopick detects and picks, then an analyst confirms and refines the event in scolv.

Frequently Asked Questions

What does scautopick do in SeisComP?

scautopick is the automatic phase picker in SeisComP. It processes continuous seismic data streams in real time, detects P and S wave arrivals and publishes phase picks without manual intervention. Those picks are consumed by other modules such as scanloc for automatic event location, which makes scautopick the foundation of rapid detection and earthquake early warning workflows. Picking algorithms and parameters are configurable per network.

What is scolv used for?

scolv is SeisComP's graphical event locator, used for manual review and quality control. A seismologist opens an event, inspects waveforms, travel-time curves and station maps, repicks P and S phases, refines the origin location, recalculates magnitude and reviews error estimates. Analysts use it to confirm or correct events detected automatically before they enter the final catalog.

Can scolv replace scautopick, or do I need both?

They complement each other rather than compete. scautopick provides fast, unattended picks that enable real-time detection, which scolv cannot do because it requires an analyst. scolv provides verified, refined event parameters that scautopick cannot produce on its own. A production SeisComP system normally runs scautopick continuously and uses scolv for review, so both are needed for an accurate catalog.

Which SeisComP module is right for earthquake early warning?

For earthquake early warning the relevant module is scautopick, because it picks phases from continuous real-time data streams within seconds and hands them to automatic location modules such as scanloc. scolv is an interactive tool and is used after the fact to verify the automatically detected events and refine their locations and magnitudes for the catalog.

How do automatic picks from scautopick get into the final event catalog?

In a typical SeisComP workflow scautopick first detects and picks phases from incoming data, and automatic location modules build a preliminary origin. A seismologist then opens that event in scolv, reviews and adjusts the picks, relocates the event and recalculates magnitudes. The refined and confirmed parameters saved from scolv become the authoritative entry in the event catalog.

Frequently Asked Questions

What does an infrasound sensor measure?

An infrasound sensor measures acoustic pressure waves at frequencies below the threshold of human hearing. These low-frequency waves are produced by earthquakes, thunderstorms, volcanic eruptions, explosions, gunshots, avalanches, landslides and heavy machinery, and because they attenuate slowly they can be detected far from the source. The SIS-1 is QuakeLogic's sensor for this band.

What is the SIS-1 infrasound sensor used for?

The SIS-1 infrasound sensor is used for environmental monitoring of natural events such as earthquakes, thunderstorms and volcanic activity; for security and surveillance, where it identifies infrasound from gunshots, explosions or other unusual activity; and for industrial monitoring, where vibrations and noise from machinery reveal early wear and the need for maintenance before costly downtime occurs.

Why is infrasound useful for nuclear test and explosion detection?

Explosions, including nuclear tests, release energy at very low acoustic frequencies that travel great distances through the atmosphere with little attenuation. Infrasound sensors can therefore detect such events from far away, which is why infrasound monitoring supports global efforts to detect unauthorized nuclear activity and why defense and security teams use it to identify blasts and gunfire.

What equipment do I need with the SIS-1 to record infrasound data?

Beyond the sensor itself, QuakeLogic offers analog dataloggers to digitize and store the SIS-1 output, and PulsePro real-time monitoring software for continuous observation and immediate analysis of infrasound data so operators can respond quickly to detected anomalies. Together the sensor, datalogger and software form a complete low-frequency acoustic monitoring chain.

Can infrasound sensors help with avalanche and landslide warning?

Yes. Avalanches and landslides emit low-frequency sound as mass moves, and detecting those signals early provides critical information for disaster preparedness and response. An infrasound sensor such as the SIS-1, installed with a datalogger and real-time software, can register these events and alert responders before visual confirmation is possible.
