Twenty years ago, the whole world witnessed how the forces of nature brutally ravaged several countries around the Indian Ocean. Over 230,000 people lost their lives, and thousands of homes and vital infrastructure were destroyed. What was the cause of this disaster, and what have we learned since?

The Research Council of Norway highlights NORSAR's pioneering work in seismology and earthquake monitoring in a new evaluation of Norwegian scientific research institutes.

Next Antarctic summer, NORSAR will install new, advanced measurement instruments—the southernmost instruments on solid rock. These devices will provide valuable insights into the structure of the Earth's crust, ice movements, and atmospheric dynamics.

NORSAR researcher Annie Jerkins defended her doctoral thesis "Improved Understanding of Seismicity in the North Sea" on Wednesday, 8 May.

Last week, a delegation from NORSAR was in the USA to participate in the annual knowledge exchange with AFTAC, a highly valuable and long-standing collaborator for us.

Turkey/Syria, Afghanistan, Morocco and Iceland in 2023, Japan in January, and most recently Taiwan. Is it normal to have so many large and devastating earthquakes in the course of a year? Earthquake expert Tormod Kværna responds.

“NORSAR and the Nuclear Test Ban” documents our over 50 years of efforts for the Comprehensive Nuclear-Test-Ban Treaty – NORSAR contributed to the negotiations leading up to the Treaty and have been central in the development of the Treaty’s verification regime. The book was initially released in print format in early 2023 and is now available to everyone in a digital version!

After two decades of reliable service, the radionuclide station RN49 at Platåberget west of Longyearbyen in Svalbard has been renewed. Last week, an expert team was on site to inspect that the station still meets the Sampling Organisation's requirements for measurement stations.

After two decades of reliable service, the radionuclide station RN49 on Platåberget, west of Longyearbyen on Svalbard, has been renewed. Last week, an expert team was on site to ensure that the station meets the CTBTO’s standards for monitoring stations.

Excellent teamwork gave results! Get an insight into our work in 2023: monitoring compliance with the Comprehensive Nuclear-Test-Ban Treaty and innovative solutions for the benefit of Norwegian society and our clients worldwide.

Marouchka Froment joined NORSAR in February as a postdoctoral researcher in the AIR project.

In 2024, despite progress, women are still underrepresented in the fields of science and technology. This International Day of Women and Girls in Science, we celebrate our female researchers at NORSAR!

The new Troll Station and research infrastructure enable Norway to continue its long tradition of polar research and contribute to the global knowledge effort. NORSAR is part of the Norwegian team that will provide access to new infrastructure in Queen Maud Land.

ISO 9001:2015 ensures quality at every level.

We are strengthening our capacity in political analysis.

NORSAR has recorded seismic signals near the Balticconnector gas pipeline in the Baltic Sea. The signals indicate a possible explosion at around 01:20, local time in Finland, 8 October 2023.

At NORSAR, we are continuously testing and developing technologies to utilize our expertise in vibration measurement and fiber optics for purposes of social benefit. Over the previous few years, we have investigated the possibility of using fiber optic sensing technology to detect water leaks in the pipeline network. The results are promising.

The next three years, the researcher project AIR, will assess the feasibility of exploring Venus’ interior using Balloon-borne seismology.

NORSAR has analysed seismic signals from regional stations in connection with the collapse of the dam in Ukraine on Tuesday 6. June 2023.

This week, NORSAR played host to representatives from AFTAC, a highly valued cooperation partner dating back to the early 1970s.
