Scientists Moot Satellite-based Earthquake Detection from Space
We may one day be able to detect earthquakes in remote areas of the Earth from space, say scientists who used a satellite to pick up low-frequency sounds from the earthquake that hit Tohoku, Japan, in March 2011.
According to a report published by scidev.net, the researchers report that the satellite is the “first seismometer in orbit”.
During an earthquake the Earth’s surface “moves like that of a drum”, creating a low-frequency sound in the atmosphere that cannot be heard by humans, said Raphaël Garcia, a researcher at the University of Toulouse, France, and the lead author of the study.
Garcia and colleagues were able to trace these acoustic waves — known as ‘infrasounds’ — from the Tohoku earthquake to the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite.
It is the first time that infrasounds have been detected in space, they say.
The European Space Agency launched the satellite in 2009 to measure the Earth’s gravity field. It orbits the earth at a relatively low altitude of about 270 kilometres — an ideal height for detecting infrasounds, which fade at higher altitudes.
It is because of this fading that researchers had previously failed to find infrasounds, despite searching for a number of years.
Now they suggest a standard altitude of about 300 km for satellite detection of infrasounds.
Other gravity-measuring satellites that have failed to detect such signals include the Challenging Minisatellite Payload (CHAMP), which orbits at 320 km, and the Gravity Recovery and Climate Experiment (GRACE), which orbits at 480 km.
GOCE was not designed to be a seismometer. “We have been interested in using data from GOCE for studying the atmosphere,” says study co-author Eelco Doornbos of Delft University of Technology in the Netherlands. “Detection of earthquakes is a spin-off of the application of the satellite.”
But it is unlikely that satellites will be able to act as real-time detectors for earthquakes on land as there was a lag of 27 minutes between the earthquake and GOCE detecting the first infrasound wave.
“An advantage of having seismometers in space would be to detect the signals from earthquakes that happen in the middle of an ocean,” said Doornbos. “But I don’t think they will replace ground-based seismometers.”
He says that more than one satellite would be necessary to detect earthquakes from space, a prospect too expensive to see in the next ten years.
But as instruments become smaller and cheaper it may “be feasible to launch a few inexpensive satellites at the same time, which might be used to help in pinpointing earthquakes”.
Doornbos adds: “At some point, the space agencies may decide that it might be a good idea to [install seismometers] on older satellites.”
Ramesh P. Singh, a geophysicist at Chapman University, United States, said that, when an earthquake occurs, ground-based seismometers provide information on the event within a few minutes. By the time GOCE detected the first signal from the Tohoku earthquake, almost half an hour later, it was already known that the earthquake had occurred.
Lagos State has become the first sub-national government in Nigeria to establish a comprehensive Greenhouse Gas Registry, a move aimed at strengthening climate governance, improving emissions accountability and accelerating the state’s transition to a low-carbon economy.
The Lagos State Greenhouse Gas Registry (LGHGR) was unveiled at the Central Business District, Alausa, Ikeja, at a ceremony attended by Prof. Akin Abayomi, commissioner for Health, members of the State Executive Council, representatives of the Federal Ministry of Environment, development partners, TPHG Technologies, the diplomatic and business communities, academics, civil society organisations and the media.
Describing the initiative as a landmark achievement in the state’s environmental sustainability drive, Dr. Babatunde Ajayi, general manager of the Lagos State Environmental Protection Agency (LASEPA), said the Registry marks a defining moment in Lagos’ climate action journey and reflects Governor Babajide Sanwo-Olu’s commitment to building a resilient, climate-smart and environmentally sustainable economy.
According to Ajayi, the digital platform will enable the state to accurately measure, monitor, report and verify greenhouse gas emissions across key sectors, providing credible data to guide environmental policies and climate interventions.
He said the Registry would strengthen evidence-based decision-making, improve transparency and accountability, support national and international climate reporting obligations, unlock carbon market opportunities and boost investor confidence in Lagos’ environmental initiatives.
Ajayi also commended TPHG Technologies for providing the technical expertise that made the pioneering project possible.
Delivering the keynote address, Prof. Abayomi described the Registry as a major milestone that positions Lagos at the forefront of climate governance and emissions accountability in both Nigeria and Africa.
He noted that climate change has evolved into a significant public health and governance challenge, stressing that access to reliable emissions data would enable the state to formulate evidence-based policies, attract climate financing, strengthen resilience and accelerate its transition to a low-carbon economy.
Providing insights into the technical framework of the project, Dr. Mofoluso Fagbeja, lead consultant and chief executive officer, TPHG Technologies, explained that the Registry was developed from the greenhouse gas inventory jointly undertaken by LASEPA and TPHG Technologies in 2022, using 2019 as the baseline year for emissions assessment.
He said the platform is designed to close critical emissions data gaps, particularly within the industrial sector, while supporting effective climate policy implementation, emissions management and sustainable development.
Fagbeja also disclosed that the greenhouse gas inventory estimated that poor air quality contributes to about 35,000 premature deaths annually in Lagos, underscoring the urgent need for stronger emissions control measures and cleaner environmental practices.
In a goodwill message, Balarabe Abbas Lawal, minister of Environment, represented by Mrs. Adenaike Olunimpe Oludunni, federal controller of Environment in Lagos, commended Lagos State for pioneering the initiative, describing it as a significant contribution to Nigeria’s climate commitments.
He said the Registry aligns with the country’s Nationally Determined Contributions (NDCs) under the Paris Agreement and supports the Federal Government’s Energy Transition Plan, while reaffirming the ministry’s commitment to deeper collaboration with Lagos State on climate governance and environmental sustainability.

Nigeria and Israel yesterday reaffirmed their commitment to deepening bilateral cooperation in research, technology and innovation as both countries pledged to expand partnerships that will drive entrepreneurship, commercialise research and accelerate economic development.
The commitment was made at the closing ceremony and innovation showcase of the I-FAIR Cohort of the Israel-Nigeria Innovation Fellowship for Aspiring Inventors and Researchers (I-FAIR) in Abuja, where the Ambassador of Israel to Nigeria, Michael Freeman, announced that funding had been secured for the fifth edition of the programme, scheduled to begin in October 2026.
Freeman described I-FAIR as a practical demonstration of the growing partnership between both countries, saying it had enabled Nigerian innovators to develop local solutions to national challenges through Israeli mentorship and expertise.
He said, “This programme has never been about bringing Israeli solutions to Nigeria. It’s been about helping brilliant Nigerian innovators develop Nigerian solutions to Nigerian challenges supported by Israeli experience, mentorship and innovation.”
The envoy noted that the initiative had brought together government, academia, investors, engineers and entrepreneurs to transform innovative ideas into businesses capable of creating jobs and stimulating economic growth.
Announcing the continuation of the programme, he said, “I am so proud to stand here today and announce that we have secured with our partners funding for I-FAIR 5 and I-FAIR 5 will be launching in October 2026.”
Freeman said the relationship between Nigeria and Israel had grown significantly over the past four and a half years through cooperation in innovation, agriculture, healthcare, education, water management and technology.
He expressed confidence that stronger collaboration between both countries would unlock greater opportunities for startups, research institutions and businesses.
According to him, “Israel brings experience and innovation, technology, agriculture, healthcare, cyber security, security and water management. Nigeria brings extraordinary talent, creativity, entrepreneurship and one of the most dynamic young populations anywhere in the world.”
He added, “I have no doubt that the best chapters of the relationship between Israel and Nigeria are still ahead of us.”
The Executive Secretary of the Tertiary Education Trust Fund, Architect Sonny Echono, also reaffirmed TETFund’s commitment to strengthening research and innovation through strategic partnerships with Israel and other stakeholders.
He said the I-FAIR programme aligned with Nigeria’s priorities in food security, agriculture, medicine, technology, clean energy and the circular economy, adding that TETFund would continue supporting initiatives that promote research commercialisation.
Echono stressed that collaboration between government, academia and industry remained critical to translating research findings into products and services.
He said, “It is this critical linkage, especially between science, engineering, technology and innovation, and the productive sector that is critical for translating R&D results and inventions into finished products for socio-economic benefits of our people.”
He disclosed that TETFund was working with partners to establish innovation facilities in about 60 tertiary institutions and had created a student innovation fund that would provide up to ₦50 million to students with commercially viable ideas.
The TETFund boss also announced plans for a National Research Fair later this year, where innovators would showcase products before policymakers, financial institutions and investors to attract funding and commercial partnerships.
Paying tribute to the outgoing Israeli ambassador, Echono described Freeman as a strong bridge between Nigeria and Israel.
He said, “Nigeria is grateful for your service. You have been a strong bridge between our two countries.”
Earlier, Head of Programmes at Innov8 Hub, Tolulope Aina, said sustainable economic development depended on building an innovation ecosystem that transforms ideas into successful businesses.
She noted that Innov8 Hub had supported more than 3,000 innovators, researchers and entrepreneurs, helping them convert research into products, startups and investment-ready ventures.
Aina said, “Nigeria does not suffer from a shortage of brilliant minds, what we need are stronger pathways that help those ideas become products, businesses, and opportunities that improve life.”
She thanked the Embassy of Israel and TETFund for their continued support in strengthening Nigeria’s innovation ecosystem.
According to her, “Building an innovation-driven economy requires collaboration, long-term commitment and shared purpose.”
