A minor, 3.3-magnitude earthquake struck in Southern California on Monday, according to the United States Geological Survey.

The temblor happened at 7:47 a.m. Pacific time about 4 miles southwest of Redlands, Calif., data from the agency shows.

U.S.G.S. data earlier reported that the magnitude was 3.4.

As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.

Aftershocks can occur days, weeks or even years after the first earthquake. These events can be of equal or larger magnitude to the initial earthquake, and they can continue to affect already damaged locations.

Iran’s foreign minister arrived in Russia on Monday, after a whirlwind weekend of diplomacy, seeking to gain political leverage and foreign backing as peace talks with the U.S. remain on hold.

But missing from this flurry of diplomacy is any sign of a meeting between Washington and Tehran.

Abbas Araghchi was in Islamabad last week but left on Saturday, prompting President Trump to cancel the U.S. negotiating team’s own planned travel to the Pakistani capital.

Araghchi went instead to Oman – which is situated directly across the Strait of Hormuz from Iran – and met Sultan Haitham bin Tariq Al and his Omani counterpart.

“Important discussions on bilateral matters and regional developments. As only Hormuz littoral states, our focus included ways to ensure safe transit that is to benefit of all dear neighbors and the world,” Araghchi said on X. “Our neighbors are our priority.”

For his part, Oman Foreign Minister Sayyid Badr bin Hamad Al Busaidi said he had “a fruitful discussion on the Strait of Hormuz…. As two coastal states, we feel our shared responsibility toward the international community and the urgent humanitarian need to release the sailors who have been detained for a long time.”

“This requires intensive diplomatic efforts and practical solutions to ensure permanent freedom of navigation,” he added.

Araghchi also spoke by phone with the foreign ministers of Saudi Arabia, Qatar and Egypt.

From Oman, he ping-ponged back to Pakistan on Sunday, and on Monday Araghchi arrived in Russia, one of Iran’s major allies.

In St. Petersburg he is expected to meet with President Vladimir Putin and plans to “discuss war-related developments and coordinate positions,” he said, according to the state-affiliated Tasnim news agency.

Who has ‘the cards’?

While in Pakistan, Iranian media reported Araghchi gave Pakistani mediators a list of “red lines” for negotiations, including on nuclear issues and the Strait of Hormuz.

Trump has repeatedly said the complete eradication of Iran’s atomic program is the key U.S. demand.

Over the weekend, Trump said: “We have all the cards. If they want to talk, they can come to us, or they can call us.”

Iran’s parliamentary speaker and lead negotiator took to social media to challenge Trump’s comments.

“They brag about the cards. Let’s see,” Mohammad Baqer Qalibaf said on X. He then presented a complicated supply and demand equation that he intended to show the economic challenges faced by the U.S.

But Iran is also facing the consequences of the U.S. Naval Blockade on its ports. Trump told Fox News on Sunday Iran has just three days of storage left before its oil pipelines explode from pressure, since it’s running out of ships to store it on.

Asked about that timeline, Amena Bakr, the head of Mideast Energy at research firm Kpler, told NPR that while Iran is running out of storage, it’s closer to 20 days at current production levels.

Bakr also said Iran has a southern terminal outside the strait of Hormuz that could be used for re-routing oil, provided they can get their ships there and bypass the U.S. blockade.
