Fortimus Smart Digital Accelerometer

Güralp, the leading global provider of force-feedback seismic monitoring instrumentation is launching Fortimus, a strong motion digital accelerometer, at the American Geophysical Union Fall Meeting this week in New Orleans, USA.

Fortimus for earthquake early warning (EEW) and structural health monitoring

The Fortimus combines the versatile Fortis sensor with the advanced data recording and software communication capability of the Minimus to deliver an advanced instrument that is compact, quick to install and simple to use.

At just 165 mm in diameter and just 84 mm high (with feet), the Fortimus boasts a host of smart features including:

  • A touch-screen 2.4 inch LCD for viewing waveforms, state of health, virtual instrument level and access to full instrument controls.
  • An ultra-low-latency mode for EEW
  • Industry standard triggering algorithms (STA/LTA)
  • Common Alert Protocol (CAP) enabled for automated emergency warning
  • Variable gain options from 0.5 g to 4 g to optimise performance for a wide range of shaking scenarios
  • Advanced network connectivity – full controls can be accessed on the instrument, via Güralp Discovery, our software platform, or via a standard web browser

The Fortimus is the latest development in the Güralp smart generation of instruments.

Philip Hill, Engineering Director at Güralp explains:

“Everyday we all play with incredibly clever technology on our phones, at home, at work, in the cloud – and we don’t think twice about it. Our aim is to utilise all the relevant technology that makes that possible and apply the best bits to our seismic instrumentation – to make it as easy as possible for our customers to get the best out of them”

For full details of the Fortimus and to view it in action, please visit Güralp at stand 1853.

Minimus seismic digitiser: Increased functionality and a new eight channel version

Following the success of the Minimus launch in 2016, Güralp, the leading global provider of force-feedback seismic monitoring instrumentation, has extended its capabilities with a host of additional features and is launching an eight channel version for multi-instrument stations at the AGU 2017 Fall Meeting.

Earthquake Early Warning (EEW) and Structural Health monitoring capabilities

The Minimus met an enthusiastic response following its launch in 2016 and since then, significant energy has been invested in further developing the digitisers’ capabilities. New out of the box features include the incorporation of industry standard triggering algorithms for EEW (STA/LTA), multi-instrument voting to mitigate false positive alerts and the Minimus is now Common Alert Protocol (CAP) for automated emergency warning. These new features make the Minimus particularly attractive for EEW and structural health monitoring applications.

New Minimus+ with eight primary digitisation channels

For increased convenience for multi-instrument stations, Güralp are also releasing a larger capacity version, the Minimus+, which offers eight primary digitisation channels. The Minimus+ can accommodate two triaxial instruments (seismometers and/or accelerometers) plus a Radian posthole or borehole and two auxiliary inputs, e.g. for infrasound and/or meteorological feeds. The Minimus+ offers all the features associated with the four channel digitiser including:

  • Advanced software communications for quick and easy instrument and data management
  • Ultra-low-latency mode for EEW - when used with GDI protocol, transmission can be achieved in 40 ms
  • GüVü Bluetooth Android App for installation integrity checking (available for both Android and iOS devices)
  • Hot-swappable data storage and dual-redundant microSD cards
  • Select from GNSS (GPS, GLONASS or BeiDou) or PTP (Precision Time Protocol) timing sources

Philip Hill, Engineering Director at Güralp discusses the developements:

"A consequence of new mobile computing technology has enabled us to miniaturise the digitiser to make the world's most portable, high performance solution. When we launched the Minimus in 2016, it reflected a step change in terms of digitiser design and user experience and, with these latest developments and the launch of the eight channel Minimus+, we have been able to release even more of that potential.”

If you are attending AGU - come and see us on booth 1853 where you can see the Minimus+ up close. Alternatively you can read more on the Minimus page.

Media Release

New ultra-low latency data transmission protocol for Earthquake Early Warning (EEW) unveiled at AGU Fall Meeting, San Francisco. GDI can transmit data 25 times faster than standard EEW protocols.

Güralp Systems Ltd, the leading global provider of seismic monitoring instrumentation and solutions, unveiled a new, free-licence, data transmission protocol that dramatically reduces the time it takes seismic instrumentation to inform Earthquake Early Warning (EEW) systems that an earthquake has occurred.

Güralp has devised a packetized data transmission protocol called Güralp Data Interchange, (GDI) that allows seismic waveforms to be transmitted sample by sample, as they are acquired by the instrumentation. To further improve speed, GDI adapts the size of the data packets it sends to suit the bandwidth available in the network. This means that transmission time is absolutely minimised for the EEW network and data can be received in as little as 30 ms.

Data protocols currently used are also packetized systems, however they require the packet to be filled to a specific size before the packet can be transmitted – and it’s this that introduces delays into the transmission process. Delays can extend to one second or more.

Working in collaboration with gempa, GDI has been incorporated into a plug-in for gempa’s SeisComPro software and is now available to existing SeisComPro customers via the CAPS plugin. For EEW networks not using SeisComPro, GDI is available as a free-license, source code download for integration into existing networks.

Dr. Chris Potts, Güralp Executive Chairman sets out the reasoning for making GDI free to use:

“As soon as we realised GDI’s potential we made the decision to make it a free-licence product. After all, we are foremost, an instrument manufacturer and not a software developer. By providing access to all interested parties, we can ensure that the global community will benefit from GDI and we hope that, by doing this, the EEW community will also contribute to its evolution, for everyone’s benefit.”

On incorporating GDI into SeisComPro, Bernd Weber, CEO, gempa GmbH explains

“GDI is one of the few acquisition modules fulfilling the requirements of EEW. With the integration into SeisComPro a modern sophisticated turnkey solution can be provided to the EEW community.”

The greatest benefit of GDI is when it is combined with low latency digitisation, such as the causal filtering in the Güralp Minimus digitiser (see Minimus brochure for more information). In this example, both digitisation and transmission can be achieved in ~40 ms, significantly less than the typical data delivery time of 1 s using other protocols.

For more information on GDI and how to download the source-code, view the GDI datasheet.

About EEW systems:

EEW systems notify users in a local or regional network when an earthquake event occurs, usually with an indication of the expected severity of the earthquake and an approximate arrival time. Generally the alert will be issued in the manner of a few, to tens, of seconds before the earthquake reaches the users. Although short, this warning time allows for automated systems to shut down services such as elevators, gas supplies and even transport networks. In addition it allows time for people to take steps to protect themselves under tables or in doorways.

The EEW community seek to maximise the warning time so that more sophisticated safety measures can be implemented. For instrument manufacturers, there are two stages where instrument design can contribute to reducing these delays - firstly the processing time required to analyse the seismic data as it arrives (this is necessary to assess the earthquake severity and location) and secondly, the time it takes for the seismic data to be transmitted to the alert system (this is often constrained by the telecommunications network being used).
