Moonquakes: Understanding the Moon’s Tectonic Forces Could Protect Future Astronauts

Space agencies and companies looking to set up lunar outposts should build far away from seismic activity.

As humanity looks to the moon for science and economic opportunity in the coming years, understanding potential dangers lurking on the lunar surface could become increasingly important.

Ridges on the moon that signify moonquakes are the subject of a recent research paper, which delves into tectonic activity across the lunar maria, a vast network of dark plains that arose from ancient volcanic activity.

A team of researchers analyzed lunar formations called small mare ridges to create a global moon map, which is the first of its kind. The paper was originally published Dec. 24 in the Planetary Science Journal.

Cole Nypaver, a postdoctoral fellow at the National Air and Space Museum’s Center for Earth and Planetary Studies and one of the paper’s authors, told CNET that the ridges that were identified were formed by faults in the lunar subsurface, which are associated with moonquakes.

“While those moonquakes are potentially hazardous for long-term lunar exploration missions or permanent outposts, they also present fantastic opportunities to learn more about the interior of the moon and how the moon formed,” Nypaver said.

The moon is shrinking

Another of the paper’s authors is a scientist named Tom Watters. Back in 2010, Watters discovered that the moon is slowly shrinking because its core is cooling.

The moon’s contraction causes disturbances on its surface. The crust gets compressed and forces material up along faults, which creates ridges, similar to how mountains form on Earth.

The most common of these ridges are called lobate scarps. They form on the lunar highlands, which are the bright spots we see when we look at the moon. But the small mare ridges only form in the lunar maria, which are the dark areas of the moon that contrast with the highlands.

This research is the first time scientists have documented the ridges throughout the lunar maria. In doing so, we now have a more complete understanding of the moon’s thermal and seismic history, which could give us a better idea of any potential moonquakes in the future.

“Our results represent the most globally complete understanding of recent lunar tectonism to date,” Nypaver said. “The presence of these additional tectonic features in the lunar maria suggests that the moon may have experienced more global contraction in the recent past than previously thought.”

Moon missions

Humans setting up permanent footholds on the lunar surface have moved from science fiction to real plans for the near future. NASA’s Artemis II mission is set to launch in March at the earliest. And while this mission will only send astronauts to orbit the moon, future Artemis missions plan to land people on the lunar surface and build permanent infrastructure there.

University of Maryland professor Nicholas Schmerr helped NASA develop the Lunar Environment Monitoring Station for Artemis 3, which the crew of the third Artemis mission, currently scheduled for 2028, will deliver to the moon’s surface.

Schmerr said to CNET that this instrument will detect seismic activity in the lunar south polar region.

“We’ll get a whole new picture of lunar seismic activity both on the South Pole and lunar farside,” Schmerr said.

LEMS-A3 is a station designed to be self-sustaining, and Schmerr will act as the instrument’s deputy principal investigator for the mission. The LEMS-A3 will assess “tectonics-related seismicity of the region and any hazard the moonquakes (or, for that matter, impacts) could pose to future longer-lived infrastructure,” Schmerr said.

Setting up shop

NASA isn’t the only one that’s looking to sustain long-term lunar operations. A company called Interlune also wants to set up mining operations on the moon to excavate helium-3, a valuable isotope that could be used for clean energy and quantum computers.

Elon Musk has been talking about building a moon base to launch AI satellites into orbit.

Getting up to speed on the areas of the moon that are more likely to experience moonquakes could influence where space agencies and private companies decide to build outposts in the future.

“There are several upcoming missions to the moon that will carry dedicated seismometers in hopes of detecting a moonquake from a small mare ridge or an asteroid impact on the moon,” Nypaver said. “By identifying a new population of tectonic features in the lunar maria, our work provides additional targets for those missions that seek to use moonquakes to better understand our closest celestial neighbor.”

Trump Maintains US‑Iran Negotiations Continue Amid Tehran’s Denials of Duplicity

President Trump insists that US‑Iran talks are ongoing despite Tehran’s denial of any negotiation plans, while warning that only a deal or total surrender will allow passage through the Strait of Hormuz. Conflicting statements from both sides have heightened uncertainty as the conflict enters its sixth month.

On Monday, President Donald Trump asserted that negotiations between the United States and Iran are still taking place, even after Tehran stated it has no intention of engaging in direct talks with Washington.

In a fiery Truth Social post, Trump labeled Iran’s leaders “unbelievably duplicitous,” claiming they are lying about ongoing peace talks “whether Iran wants to admit it or not.” He repeated his assertion that the United States completely controls the Strait of Hormuz, despite maritime traffic through the crucial route lingering at only a small fraction of pre‑conflict levels.

He wrote, “Nothing reaches Iran unless we allow it, and nothing will pass unless a deal—or total surrender—is achieved.”

Earlier that day, Iranian Foreign Ministry spokesperson Esmail Baghaei told reporters there is no imminent plan for U.S.–Iran negotiations, contradicting Trump’s earlier comment that talks would resume Monday afternoon. Baghaei added that Iran’s only current discussions are with Oman concerning the Strait of Hormuz.

The conflicting statements have heightened uncertainty over the peace‑talk process and the broader conflict, now in its sixth month.

Trump’s assertion about new negotiations came a day after he said on Truth Social that he had agreed to cancel a massive strike against Iran “subject to being able to rapidly make a DEAL.” He said in the same post that Iran and other Middle Eastern countries had asked him to hold off on that attack because “the perimeters of a deal has been agreed to.”

Trump has claimed dozens of times throughout the more‑than‑five‑month‑long war that a deal is at hand. No permanent deal has been signed, and a temporary ceasefire reached in June has fallen apart.

Trump has also repeatedly threatened to launch devastating strikes against Iran before backing off. After the latest example, oil prices on Monday fell and stocks surged.

BMI, a research unit of Fitch Solutions, said in a note Monday that a broader diplomatic understanding on reopening the Strait of Hormuz is still achievable this quarter, while raising the probability of its escalation scenario to 35% from 25%, citing mounting military, diplomatic and economic signs of rising U.S.-Iran tensions.

“Diplomatic progress is likely to be punctuated by periodic military flare-ups, while miscalculation by either side could trigger a renewed escalation,” BMI analysts wrote in a note. The firm said the key issue to watch is the future governance of the strait, as the Iran-Oman talks — potentially backed by Gulf states, China and the U.S. — point to efforts to build a post-conflict shipping framework.

Shipping risks persist even as diplomacy appears to be advancing. The United Kingdom Maritime Trade Operations Centre said it received a report of an incident 20 nautical miles (23 miles) northeast of Khasab, Oman — at the mouth of the strait — with a tanker’s master reporting an explosion in close proximity to the vessel at about 20:37 UTC Sunday (4:37 pm ET). The vessel and crew were safe and authorities are investigating, UKMTO said, advising ships to transit with caution.

The proposal Trump announced over the weekend calls for the U.S. and Iran to return to negotiations and continue ironing out some of the thorny issues that had derailed diplomatic efforts, according to The Associated Press, citing a regional official involved in the mediation efforts.

The official said the proposal also includes a reopening of the Hormuz Strait and halting attacks across the region, including by Iranian-backed militias in Iraq on the Arab Gulf countries and Jordan.

The U.S., for its part, will end its naval blockade on Iran and allow Tehran to export its oil, the official said, adding that no deal has been reached, although the mediation efforts remained underway.

Trump’s weekend reversal has lowered the temperature after days of escalating attacks across the Gulf. Kuwait said Saturday that Iranian forces launched a wave of drones within its airspace, with its military destroying multiple aircraft after Iran targeted critical infrastructure in the country’s north.

A parallel track with Muscat is also advancing. Iranian diplomats said Tehran was close to reaching a new arrangement with Oman to manage shipping through the Strait of Hormuz, a deal critical to preventing the war from escalating further, according to the Financial Times.

Iranian officials said negotiations over future management of the Hormuz Strait with Oman, which sits on the opposite shore of the waterway, are in their final stages. The agreed shipping route would be different from those used before, according to Iran’s Foreign Ministry spokesperson, Baghaei, adding that the new route was separate from the issue of the strait’s reopening or continued closure.

Oil Prices Slide as Trump Halts Planned Iran Strike

Oil prices dropped after Trump cancelled a planned strike on Iran, with WTI down about 5% and Brent near 5% lower. He said the move followed requests from Tehran and regional allies for a pause while a deal shaping the Strait of Hormuz and Iran’s nuclear program is negotiated.

Oil prices fell on Monday after President Donald Trump announced he had cancelled a planned strike on Iran. WTI futures dropped roughly 5% to $80.34 a barrel, while Brent slipped about 4.7% to $83.77 a barrel.

Trump said early Sunday he called off the strike after Iran and several Middle Eastern nations asked him to hold off, noting that the outlines of a deal had been agreed upon. He added that the prospective accord would entail the immediate, full opening of the Strait of Hormuz and an end to Iran’s nuclear ambitions, according to his Truth Social post.

The president had been considering another round of strikes as diplomatic hopes waned since the conflict began on February 28. He said the U.S. and Iran would meet for talks on Monday, but Iran denied any scheduled negotiations with Washington, citing PressTV. Iran’s foreign‑ministry spokesperson Esmaeil Baghaei clarified that Tehran was only discussing shipping routes through the Strait of Hormuz with Oman. In a follow‑up Truth Social message, Trump insisted that, regardless of Iran’s acknowledgment, the United States is indeed discussing a solution to a long‑standing problem created by Iran.

Oil Prices Drop as Trump Cancels Planned Attack on Iran

Oil prices fell sharply after President Trump announced the cancellation of a planned strike on Iran, citing a new deal that would open the Hormuz Strait and end Iran’s nuclear threat.

Oil prices fell sharply on Monday after President Donald Trump announced that he had called off a planned strike on Iran.

West Texas Intermediate futures, the U.S. benchmark, slipped roughly 5% to close at $80.34 per barrel, while Brent crude, the international benchmark, declined 4.7% to settle at $83.77 a barrel.

Trump made the announcement early Sunday, saying he had canceled the strike following requests from Tehran and other Middle Eastern countries.

In a Truth Social post, he wrote: “We have just been asked by Iran, and other Middle Eastern Countries, to hold off any attack in that the perimeters of a deal has been agreed to.”

The president indicated that the proposed agreement would include the immediate, complete, and total opening of the Hormuz Strait, as well as an end to Iran’s nuclear threat.

Trump had been weighing additional strikes amid diminishing prospects for a diplomatic resolution to the conflict that began on Feb. 28. He stated that the U.S. and Iran would hold negotiations on Monday.

Tehran denied that talks were planned with Washington, according to state news outlet PressTV.

Iran’s Foreign Ministry spokesman Esmaeil Baghaei said Tehran was only holding talks with Oman regarding the routes ships can use through the Strait of Hormuz.

In a subsequent Truth Social post, Trump added that whether “Iran wants to admit it or not, we are, in fact, talking of a solution to a problem that they have caused for decades.”
