The authorities in Greece on Monday closed schools and deployed emergency services on the Aegean island of Santorini, one of the country’s most popular tourist destinations, after the area was rattled by hundreds of minor and moderate earthquakes.

The ministry for civil protection said on Sunday that more than 200 tremors had struck the Aegean region between Santorini and Amorgos in the past 48 hours. They continued into Monday, shaking residents sometimes every few minutes. Precautions were also taken on several other islands affected by the tremors, with schools closed and emergency teams on standby.

Gerasimos Papadopoulos, a seismologist, wrote on Facebook that the quakes had been increasing in magnitude, calling them an “intense pre-seismic sequence.”

Prime Minister Kyriakos Mitsotakis, speaking from Brussels, where he is attending a meeting of European Union leaders, appealed to islanders to “be calm and follow civil protection orders.”

Most of the tremors were minor, but some exceeded magnitude 4.5, and Mr. Papadopoulos referred to readings of 4.7 and 4.9 in his Facebook post.

There were no reports of injuries, and only minimal damage, including minor landslides, was recorded by the authorities. Greece sits on multiple fault lines and is often rattled by earthquakes, but such a sequence of tremors growing in intensity is less common.

The Greek Organization of Earthquake Planning and Protection on Sunday advised islanders to avoid large gatherings in enclosed spaces, stay away from ports near cliffs and empty swimming pools to reduce potential damage to buildings. Emergency workers set up tents in outdoor sports venues, and the local authorities designated meeting points for potential evacuations.

The measures were precautionary, Greece’s civil protection minister, Vassilis Kikilias, said on Sunday, but he urged citizens to “strictly follow safety recommendations to minimize risk.”

The extent of that risk was unclear, with some experts playing down the potential for a major earthquake and stressing that the seismic activity was not linked to a dormant volcano on Santorini.

The chances of a much bigger and more damaging quake were “very small, that’s the extreme scenario,” Efthimios Lekkas, director of the earthquake planning organization, told Greek television on Monday. Referring to the potential for an eruption on Santorini, he said, “The volcano may awaken, but there’s no way we will have an explosion.” Mr. Lekkas said on Saturday that the volcano had produced very large eruptions only every 20,000 years.

The last one occurred more than 3,500 years ago, forming Santorini’s unique caldera, multicolored beaches and rock formations, which draw more than three million visitors annually. Since then the area has seen only a minor eruption, in 1950, that caused no casualties.

The island’s last major earthquake was in 1956, when a series of temblors of magnitude 7 to 7.7 killed 53 people and destroyed hundreds of homes.

Since then, no major tremors have occurred, though a series of smaller quakes also occurred during 14 months in 2011 and 2012, with shaking that diminished in intensity. Similar measures to those instituted this time around were not taken then, according to local officials.

In an interview with Volcano TV, a local station, on Sunday, Santorini’s mayor, Nikos Zorzos, said that the current precautionary measures, with emergency vehicles on the island’s roads, “might be excessive.” But he told national TV on Monday that the guidelines of expert committees should be followed.

Reports also suggested that thousands of people were looking to depart the island. Nonetheless, Mr. Zorzos said, “There is no mass exodus, some people are choosing to leave.”

Greek television on Monday showed dozens of cars waiting at Santorini’s main port, while Aegean Airlines said that it had added three additional flights from the island on Monday and Tuesday.

Mr. Zorzos had been due in Athens on Monday to open the island’s annual tourism campaign, an event that was canceled on Sunday night.

The impact on tourism on the island was unclear, though the British Foreign Office included the official warnings in its online travel advisory for Greece.

It’s been called the Trump playbook, the Trump card, the Trumpist approach, campaigning as “Donald Trump lite” and even “going full Trump.”

Election season is heating up in Australia, where the opposition leader, Peter Dutton, has been sounding a lot like President Trump. He has lashed out at a “woke brigade” of banks, grocery stores and a chain of pubs for addressing environmental and Indigenous issues. He has lamented about young men being “disenfranchised and ostracized” by diversity initiatives. And he’s set up a shadow minister for government efficiency.

Mr. Dutton, the head of Australia’s main center-right political party, hopes to oust Prime Minister Anthony Albanese in an election that must be held by May 17. Mr. Albanese has been under pressure to rein in post-pandemic inflation, and Mr. Dutton has accused him of being too distracted by “woke” issues, like Indigenous rights, to address high prices and unaffordable housing.

But last week, a widely followed poll had Mr. Albanese’s approval rating at its lowest point since he came to power in 2022. Fifty-seven percent of respondents in the NewsPoll survey said they disapproved of his performance. A head-to-head comparison showed Mr. Dutton closing in on Mr. Albanese, a sign that his political messaging was getting at least some traction.

“What I like about Dutton is he doesn’t sit on the fence,” said Louise Pridham, 57, a retired nurse who lives in the Sydney suburb of Cronulla. She and her husband, Nigel Pridham, a 57-year-old builder, said they were not Trump fans but felt validated by some of Mr. Dutton’s messaging, which Mr. Pridham acknowledged had a Trump-like quality.

Ms. Pridham said more people she knew seemed to be appreciating Mr. Dutton’s bluntness. “He says as it is. There’s no wokeness in it.”

The parallels between Mr. Trump and Mr. Dutton, a 57-year-old former policeman known for his tough stances on immigration and asylum seekers, are drawn by both supporters and critics. Mr. Dutton has not shied away from the allusion; on Friday, he railed about the government’s diversity and inclusion efforts, hours after Mr. Trump, without offering evidence, blamed D.E.I. policies for a deadly plane-helicopter collision outside Washington.

“Positions advertised have included culture, diversity and inclusion advisers, change managers and internal communication specialists,” Mr. Dutton said, referring to job openings in the government. “Such positions, as I say, do nothing to improve the lives of everyday Australians.”

Mr. Dutton’s office did not respond to requests for comment.

Mr. Trump’s return to office has emboldened a range of right-wing politicians across Europe to harden their rhetoric, solidify their bases and expand their ambitions.

But in Australia, the influences are more muddled. In 2019, a survey found that the conservative base in Australia was far more ideologically aligned with Hillary Clinton backers in the United States than with Trump supporters. Last year, barely a fifth of Australian voters said in a survey that they would have chosen Mr. Trump over then-Vice President Kamala Harris if the U.S. election were up to them.

Mr. Dutton made clear his distaste for “wokeness” as early as 2021, when as defense minister he banned events where staff members wore rainbow-colored clothing to support L.G.B.T.Q. awareness.

Two years later, conservatives were energized by a watershed moment in Australia’s culture wars. In 2023, a proposal to give Indigenous Australians a voice in Parliament in the form of an advisory body was rejected soundly by voters in a referendum. It had been a landmark effort for Mr. Albanese, and its defeat, his opponents argued, meant a majority of Australians felt that placing too much emphasis on the country’s colonial sins was divisive.

One of Mr. Dutton’s rallying cries has been his defense of Australia Day, the annual Jan. 26 holiday marking the day British settlers first landed in the Sydney area. In recent years, people who see it as a celebration of brutal colonial oppression of the Aboriginal population have called for abolishing the holiday or moving it to a different date.

But a survey conducted last month by The Sydney Morning Herald found that 61 percent of Australians supported keeping Australia Day as it is, up from 47 percent a year earlier.

Mark Kenny, the director of the Australian Studies Institute at the Australian National University, said Mr. Dutton’s rhetoric appealed to a working-class base, which, like its American counterpart, sees itself as having been abandoned by economic shifts, including the decline of manufacturing. Those voters felt let down by their traditional political leadership on the left, he said.

“What you’ve got there is a kind of long-simmering sense of dissatisfaction, of being ignored, of not heard, being left behind,” he said. “When Dutton says ‘woke,’ it’s lazy and imprecise, but that doesn’t matter. People can attach to it what they think.”

It is unlikely that Mr. Dutton can win just by mobilizing single-issue voters. That’s because voting is compulsory in Australia, with the threat of a fine for noncompliance, and turnout typically exceeds 90 percent.

As readily as he has adopted some of Mr. Trump’s language and priorities, Mr. Dutton has drawn the line at others, resisting pressure from a coalition partner to campaign on transgender issues. He has also indicated that he would not consider withdrawing Australia from the Paris Agreement, the international climate accord.

To Graeme Turner, emeritus professor of cultural studies at the University of Queensland, Mr. Dutton’s use of Mr. Trump’s words and rhetoric seem a lot more opportunistic than substantive.

“I doubt you could find a politician who could define the word ‘woke,’” Mr. Turner said. “It’s become a really handy slogan as a way of smearing any idea they don’t like, as a way of pre-empting it from serious analysis.”

The sniping over Australia Day continued last week. Sussan Ley, the deputy leader of Mr. Dutton’s party, marked the holiday by likening the arrival of British colonizers to Elon Musk’s ambitions to settle Mars. “They did not come to destroy or to pillage,” she said, in comments that were promptly criticized and lampooned.

The day before, at the spot where Captain James Cook first landed in Australia in 1770 — now a national park — a smattering of families sprawled out on grassy knolls and enjoyed a leisurely, sunny afternoon.

“It wouldn’t matter to me if you change the date because it’s not that big a deal,” John Gallop said of the holiday that was causing so much fuss among politicians. He said it was his first visit to the site in more than 50 years of living in Sydney, and that he had only come at the urging of his wife, who is from the Philippines.

“There’s so much more we need to change in Australia,” he said.
