News from Lennartz and from around the world

November 2002: Lennartz starts operating its own seismological station (code: TUBL) using new LE-3D Borehole sensor and M24 Compact/LP six channels

More details available here. We will soon have further details on the process of drilling and tubing the borehole, including a DVD video that you will be able to order from us. Stay tuned!

Lennartz apprentice now new employee

After having been formally trained for two and a half years, Andreas Rupp recently passed his final exam with flying colors. After having passed a similar exam as a certified mechanic a couple of years ago, he decided he wanted to get additional education in electronics. Under the auspices of Dietmar Löffler, Andreas came out first among his peers.On March 13, 2002, he was awarded a prize at a ceremony held at the local Chamber of Commerce:

First "detached office" of INGV inaugurated on May 24, 2001; equipped with Lennartz M24 system

In the beautiful Tuscan town of Arezzo (which, by the way, serves as the backdrop to Roberto Benigni's triple Academy Award winning movie "La vita è bella" [Life is beautiful]), the first "sede distaccata" ("detached office") of the National Institute of Geophysics and Volcanology (INGV) was inaugurated on May 24.

Professor Enzo Boschi, director of INGV, was among the approximately 100 attendees, and found himself under siege by the press.

The future director of the observatory, native German Thomas Braun, suffered a similar fate:

Here is a shot from the press conference:

Press Conference

However, all the information given during the press conference did not keep the journalists from using a slightly over-optimistic vocabulary: "An antenna to catch earthquakes" - "Now there is a sentinel for the earthquake risk" - "Earthquakes are less frightening now". Oh well..

The new observatory is intended to become a hub for seismological data from the whole territory of Tuscany. Currently it is equipped with a single Lennartz M24 Digitizer, connected to a Linux PC running the SeisComP software (see below for details). In the future, both a classical local seismic network and an array (hence probably the allusion to "antenna" in the press) are to be installed.



The M24 Digitizer now works with SeisComP/Seedlink software

November 23, 2000: Lennartz now provides a software driver that makes the M24 Digitizer (3 channels, 24 bits) fully compliant with the Seiscomp/Seedlink software. This software package, used in the German Regional Seismic Network (GRSN), has been developed by the GEOFON group at GFZ Potsdam (headed by Dr. Winfried Hanka) and has recently been greatly expanded and overhauled by Andres Heinloo of Tallinn, Estonia. For more details please continue here.

A comprehensive article describing the scope of SeisComP/Seedlink is available in the December 2000 edition of the ORFEUS Newsletter: go here.


New Lennartz building inaugurated November 18, 2000

A group of more than 100 invitees gathered on Saturday Nov. 18 to celebrate the formal opening of Lennartz electronic's new premises. Part refurbished, part brand new, the Lennartz facilities now total approximately 1,000 square meters.

The party started with a video presentation. Construction work took the better part of 18 months. To those of you used to work in prefab cubicles this may seem excessive, but you know how those Germans are... everything done with utterly unnerving diligence and attention to detail :-)
Dr. Wolfgang Brüstle, head of Baden-Württemberg's Federal Earthquake Service in Freiburg, gives a speech on earthquakes in general, and earthquake hazard in our area.

The audience being some fellow scientists but mostly laypersons (almost all the builders were there, as well as friends and relations of Lennartz employees), it was not trivial to strike the balance. It is easy to give a "sloppy" talk about earthquakes so that anybody will understand you, but under the scrutiny of your peers you better stick to the facts. I am happy to report that both presenters fared admirably well.

Prof. Erhard Wielandt (Institute of Geophysics, Stuttgart) gives a talk on our current knowledge of the Earth's inner structure, and seismology's contribution to this knowledge.
Both guests were (gently :-) forced to sign our guestbook.


Newsletter 14 now available on-line

November 14, 2000: The latest edition of the Lennartz Newsletter is now available in four different versions. A "screen only" version with low-resolution (72 dpi) images (approx. 212 kB) in German and English, and a "high-quality print" version (approx. 550 kB), again in German and English. ATTENTION! You will need Acrobat Reader 4.x. The outdated version 3.x will no longer work on these documents.


Geological Research Authority of Sudan (GRAS) orders MARS-88/RC network

Spring 2000: A new network based on MARS-88/RC digital two-way telemetry technology has been ordered by the Geological Research Authority of Sudan (GRAS). The network headquarters will be located in the country's capital Khartoum. Two trainees visited Lennartz electronic GmbH for a two-week factory training in June. The system (basically a turnkey system except for the antenna masts which will be procured locally) shipped in early July.

Baden-Württemberg's Landeserdbebendienst with on-line seismograms from Lennartz MARS-88 stations

January 1999: Having run a seven-station digital MARS-88 ISDN network for a couple of years already, Baden-Württemberg's Landeserdbebendienst (State Earthquake Service), located in Freiburg, has recently begun putting their location results and seismograms on the Internet. Check http://www.lgrb.uni-freiburg.de/d/fach/led/led_2_1.htm for up-to-date information.


MARS-88 network on Azores Islands up and running

January 1999: Encouraged by the ongoing success of a multi-station national network covering mainland Portugal, the National Institute of Meteorology in Lisbon had decided some time ago to install a radio telemetry MARS-88 network in the Azores Islands. Situated between the European and North American continents, these islands are famous for their benign climate ("springtime the whole year round").

Azores mapIt so happened, though, that abominable weather conditions turned out to be the greatest obstacle during installation work... telemetry antenna poles could not be erected due to high winds, ships were forced to stay at port... some springtime here :-)

Anyway, the work has been completed nevertheless, and the system is happily transmitting data to the islands headquarters. The SPARCstation there is connected to the Lisbon headquarters by a dial-up PPP link, mirroring important waveform data and making them available for merging with the mainland database.

Later this year, the third and final installment of instruments will complete the network. The analogue (FM) Lennartz network that had been in operation for decades will then be retired for good.

More information can be found here (in Portuguese only, though).
