This spring Gaiacode will attend two important scientific conferences. We will first participate in the annual meeting of the Seismological Society of America (SSA) in Puerto Rico. A week later, we will be present at the general assembly of the European Geophysical Union (EGU) in Vienna. Besides showing our full product line, we will present a completely new sensor design in technical contributions at each conference.

SSA in Puerto RicoSSA

The members of the SSA and their guests will gather for their annual meeting from 17 to 20 April 2023 at the Puerto Rico Convention center in downtown San Juan, the capital of this Carribean Island, a territory of the United States. For our presentation, we have teamed up with our Latin American partner Ampere to show our product line and the various services provided by the technical team of Ampere. Come and visit us at exhibit booth # 26 in the Convention Center.

EGU in Vienna EGU

Just a week later, from 24 to 28 April 2023, the EGU will hold its general assembly in the Austria Center located on the Donauinsel in the heart of Austria's capital Vienna. Our team will show our product line and discuss current and future developments in seismic instrumentation. Come and visit us at booth # 08 in the exhibition entrance hall of the Austria Center.

A completely new seismic sensor design

 In addition to showing the product line, we will present technical contributions at both conferences. In them we will describe details of a newly developed and implemented approach to the design of seismic sensors, the first truly very broadband feedback seismometer. It has a flat amplitude response to ground vibration in the frequency range of 270 Hz to 360 sec. The abstract of our paper can be found below.Abstract
