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.

NITDA Explores Partnership with Trust Stamp on Digital Trust and Innovation

By Naeemah Junaid
The National Information Technology Development Agency (NITDA) has held strategic discussions with representatives of Trust Stamp, a NASDAQ-listed global technology company, to explore potential areas of partnership aimed at strengthening Nigeria’s digital trust framework and advancing innovation within the digital economy.

The meeting, chaired by NITDA Director General, Kashifu Inuwa Abdullahi, focused on identifying collaborative opportunities aligned with Nigeria’s digital transformation agenda and the Agency’s strategic priorities for building a secure, inclusive, and innovation-driven digital ecosystem.
Inuwa emphasised that trust remains a critical foundation for the growth of the digital economy, noting that secure systems and strong cybersecurity frameworks are essential for driving innovation, economic growth, and national development. He stated that building trust in digital platforms and services is key to accelerating adoption and unlocking opportunities across sectors.
He reiterated NITDA’s mandate as a regulator to create an enabling environment through forward-looking policies and regulatory frameworks that support innovation rather than promote specific technologies. According to him, government interventions are designed to stimulate markets, create opportunities, and empower both businesses and citizens to participate fully in the digital economy.
The Director General further reaffirmed Nigeria’s openness to investments that strengthen digital infrastructure and enhance digital services, stressing that sustainable national development is best driven by private sector participation under supportive regulatory and policy frameworks. He called for continued engagement to ensure alignment with national priorities and effective integration into Nigeria’s digital ecosystem.
In his remarks, Trust Stamp Vice President, Jonathan Pasha, highlighted the company’s global experience in secure verification and trust technologies, describing its approach as partnership-oriented and focused on delivering long-term value within local ecosystems. He noted that the company prioritises collaboration with governments and private sector stakeholders to address local challenges and expand access to secure digital services.
Pasha referenced Trust Stamp’s ongoing operations in Nigeria, including its collaboration with a telecommunications provider to enhance SIM swap prevention and fraud detection capabilities. He also outlined the firm’s biometric tokenisation technology, which converts biometric data into secure, privacy-preserving representations, enabling verification processes without exposing sensitive information.
He explained that the technology supports secure verification, fraud prevention, financial inclusion initiatives, and the tokenisation of real-world assets, while being designed to function effectively in low-connectivity environments and on low-specification devices to expand access to digital services.
Both parties expressed interest in advancing technical-level discussions to identify specific areas of collaboration aligned with national priorities and Nigeria’s digital transformation objectives.
NITDA reaffirmed its commitment to fostering a secure and trusted digital economy through strategic partnerships, robust regulatory frameworks, and initiatives that promote innovation, inclusion, and sustainable growth.

NDIC Moves to Boost Customers’ Confidence in Nigerian Banks

The Nigeria Deposit Insurance Corporation (NDIC) has reaffirmed its commitment to safeguarding the nation’s financial system, announcing that its recent upward review of the maximum deposit insurance coverage now protects about 99% of depositors in the Country.

Kabir Katata, Executive Director (Operations), NDIC, stated this on Wednesday at the Corporation’s 2025 Stakeholders’ Town Hall Meeting held in Enugu.
Katata, while speaking on the theme, “Deepening Stakeholder Engagement,” said the policy to expand deposit insurance coverage was deliberately designed to protect small savers, promote financial inclusion and strengthen public confidence in the banking sector.
He explained that the town hall meeting was aimed at engaging stakeholders across various sectors, including academia, market associations and civil society groups.
“The essence of this town hall meeting is to interact with our stakeholders, tell them what we do and listen to their questions so they can better understand the role NDIC plays in society. We guarantee depositors’ funds and supervise banks to ensure that depositors are protected”, he said.
Katata noted that following the 2024 review of deposit insurance coverage, depositors in Deposit Money Banks (DMBs), Mobile Money Operators (MMOs) and Non-Interest Banks (NIBs) are now insured up to N5 million per depositor.
Similarly, depositors in Microfinance Banks (MFBs), Primary Mortgage Banks (PMBs) and Payment Service Banks (PSBs) now enjoy insurance coverage of up to N2 million per depositor.
“This means that in the event of a bank failure, depositors are promptly paid up to the insured limit,” he said.
He added that depositors with balances exceeding the insured limit would receive the initial insured sum, while the outstanding balance would be paid as liquidation dividends upon realisation of the failed bank’s assets and recovery of debts.
Highlighting improvements in the payout process, Katata referenced the recent resolution of defunct institutions, including Heritage Bank Limited, Union Homes PLC and Aso Savings and Loans PLC.
He said that the Corporation successfully leveraged the Bank Verification Number (BVN) as a unique identifier to trace depositors’ alternative accounts and transfer insured sums within days of bank closures.
“I urge all depositors to ensure that their BVN is properly linked to their bank accounts and identity records. This greatly facilitates seamless and timely access to insured deposits in the event of bank failure,” he advised.
Katata emphasised that although the NDIC works closely with the Central Bank of Nigeria (CBN) to ensure sound corporate governance and regulatory compliance in banks, financial system stability remains a shared responsibility.
“While the CBN and NDIC continue to strengthen oversight, depositors also have a responsibility to remain vigilant and well-informed,” he said.
