Fast Radio Bursts (FRBs), potent surges of radio energy that remain largely unexplained in the field of astronomy, have been studied in a recent University of Tokyo investigation that draws a connection between these bursts and seismic activity on Earth. The study posits that starquakes occurring on neutron stars could be the source of these FRBs. Such findings have the potential to significantly advance our comprehension of seismic phenomena, high-density matter, and even nuclear physics.
A recent scientific endeavor at the University of Tokyo has shed light on a potential link between Fast Radio Bursts (FRBs) and starquakes occurring on neutron stars. This correlation could offer revolutionary perspectives on our understanding of seismic events and nuclear physics.
FRBs, which elude straightforward explanation, produce enormous yet invisible energy surges in radio frequencies that are detected by radio telescopes. Prior research had established some general similarities between the energy patterns of recurring FRBs and those of earthquakes and solar flares.
Nevertheless, the latest inquiry at the University of Tokyo analyzed the temporal and energy-related characteristics of FRBs, revealing significant similarities with earthquakes but marked differences with solar flares. This bolsters the hypothesis that starquakes on neutron stars may be the genesis of FRBs. Such a realization could facilitate deeper understanding of seismic behavior, the properties of high-density matter, and nuclear physics fundamentals.
Data for the study came from the Five-hundred-meter Aperture Spherical Telescope (FAST) in China and the Arecibo Telescope in Puerto Rico, among the world’s largest single-dish telescopes. It is noteworthy that the Arecibo Telescope was decommissioned due to damage in 2020.

The Enigma Surrounding FRBs
The expansive realm of outer space harbors numerous unresolved questions. Despite the allure of unexplored territories, there is a considerable body of knowledge that can be amassed right here on Earth. Technological advancements have granted us the ability to scrutinize the Martian surface, be awed by Saturn’s rings, and receive cryptic signals from the depths of space. FRBs are prodigiously strong, bright energy discharges that manifest on radio wavelengths.
Discovered initially in 2007, these bursts can traverse billions of light years, yet endure for only a few milliseconds. Current estimations suggest that nearly 10,000 FRBs may occur daily if one could survey the entire sky. Interestingly, of all detected FRBs thus far, roughly 50 have been identified as originating from recurring sources.
Theories Pertaining to the Origin of FRBs
The underlying cause of FRBs has not been definitively identified. Various hypotheses have been proposed, ranging from extraterrestrial activity to phenomena involving neutron stars. These latter stars are formed following the implosion of a supergiant star, resulting in a densely packed core with diameters between 20 and 40 kilometers. Magnetars, a specific type of neutron star with incredibly powerful magnetic fields, have been observed emitting FRBs.
Statistical Exploration and Conclusions
Previous statistical analyses have mainly concentrated on the time intervals between consecutive bursts. However, researchers from the University of Tokyo chose to employ a two-dimensional spatial analysis, evaluating nearly 7,000 bursts from three distinct repeating FRB sources. They applied a similar methodology to earthquake and solar flare data for comparison.
The study revealed striking parallels between FRBs and earthquakes but distinct dissimilarities with solar flares. The research team asserts that this implies the presence of a solid crust on neutron stars, which when subjected to starquakes, discharge immense energy detectable as FRBs. Future research endeavors are planned to confirm these intriguing similarities.
By exploring seismic activity in such unique cosmic environments, we may glean newfound understanding into Earth’s earthquakes. “Neutron stars present the universe’s densest environments, comparable to atomic nuclei. This opens the possibility for novel insights into ultra-high-density matter and the basic principles of nuclear physics,” stated Professor Tomonori Totani.

Frequently Asked Questions (FAQs) about Fast Radio Bursts and Starquakes
What are Fast Radio Bursts (FRBs)?
Fast Radio Bursts (FRBs) are extremely potent surges of radio energy that remain largely unexplained. They are invisible to the human eye but are detected by radio telescopes. First discovered in 2007, these bursts can travel billions of light years and typically last only a few milliseconds.
What is the University of Tokyo’s recent research about?
The University of Tokyo has conducted a study that explores the potential link between FRBs and seismic activity on Earth. The research posits that “starquakes” on neutron stars might be the source of these mysterious FRBs. The study aims to offer new perspectives on seismic events, high-density matter, and nuclear physics.
How does the research draw a parallel between FRBs and earthquakes?
The researchers analyzed the time and energy distribution of FRB and earthquake events. They found notable similarities between the two in several ways, such as the probability of aftershocks occurring for a single event and the aftershock rate decreasing with time. This supports the hypothesis that FRBs might be caused by starquakes on neutron stars.
What are starquakes and how are they related to neutron stars?
Starquakes are seismic activities occurring on the surface of neutron stars. A neutron star forms when a supergiant star collapses, resulting in a highly dense core. Starquakes on these solid crusts of neutron stars can release huge amounts of energy, which may manifest as FRBs.
What is the role of Magnetars in this research?
Magnetars are a specific type of neutron star with extremely powerful magnetic fields. They have been observed to emit FRBs. The study considers the possibility that the surface of a magnetar could experience a starquake, leading to the emission of an FRB.
What were the sources of data for this research?
The study relied on data from the Five-hundred-meter Aperture Spherical Telescope (FAST) in China and the now-decommissioned Arecibo Telescope in Puerto Rico. These are among the world’s largest single-dish telescopes.
What are the implications of this research?
If the link between FRBs and starquakes is confirmed, it could significantly advance our understanding of seismic phenomena, high-density matter, and even nuclear physics. By studying seismic activity in neutron stars, scientists may gain new insights into earthquakes on Earth.
What is the next step for this research?
The researchers plan to continue analyzing new data on FRBs to validate the similarities they have found between FRBs and earthquakes. The aim is to confirm whether these observed phenomena are universally applicable.
Is the cause of FRBs conclusively identified?
No, the underlying cause of FRBs has not been definitively identified. The University of Tokyo’s research offers a plausible explanation but requires further verification. Various other hypotheses, including extraterrestrial origins, have also been proposed.
Where was the research published?
The research, authored by Tomonori Totani and Yuya Tsuzuki, was published in the Monthly Notices of the Royal Astronomical Society on October 11, 2023. The DOI is 10.1093/mnras/stad2532.

Hold up, this research used data from Arecibo? I thought that telescope was decommissioned. Good thing they got the data in time.
It’s articles like this that make me regret sleeping through my science classes. So much to learn, so little time.
Wow, this is mind-blowing stuff. Never thought FRBs could be related to quakes on neutron stars. Science just keeps getting cooler and cooler, doesn’t it?
Im not a science guy but this is super interesting. Makes ya think what else is out there in space that we dont know bout yet.
what’s the deal with magnetars? They sound like something out of a sci-fi novel but apparently, they’re emitting these FRBs. Need to read up more on this!
If they prove this theory, it’s gonna be huge. Imagine, new insights into earthquakes and nuclear physics just by lookin’ up at the sky. Whoa.
so, are we saying earthquakes and starquakes are like long-lost twins? That’s some next-level connections right there!
The implications are huge. If we can learn about high-density matter in neutron stars, we could possibly advance nuclear physics. This is a big deal, people.
The article is dense but so fascinating. It also seems to imply that understanding starquakes could help us understand earthquakes better. Killing two birds with one stone, eh?
This feels like science fiction come to life. I mean, starquakes? Seriously, can’t wait for more studies to dig deeper into this.
