10,000 tremors How Turkey has been rattled by aftershocks since the Feb. 6 earthquakeThousands of earthquakes struck southern Turkey in the weeks after a 7.8 magnitude earthquake on Feb. 6, killing more than 50,000 people in Turkey and northwest Syria. Chart shows about ten thousand earthquakes that have been recorded in southern Turkey since a 7.8 magnitude earthquake occurred on February 6. The Turkey quake also triggered a magnitude 7.5 earthquake that caused a separate rupture in the Earth’s surface, which in turn caused thousands of aftershocks. Domino effect Seismologists define aftershocks as temblors triggered by a large earthquake, close in time and location. Chart shows aftershocks that occurred in 24 hours after the 6.4 magnitude earthquake in southern Turkey within 30 kilometers around the city of Antakya.
Russia, without providing evidence, has repeatedly said the West was behind the blasts affecting the Nord Stream 1 and 2 pipelines last September - multibillion-dollar infrastructure projects that carried Russian gas to Germany. In his blog post, entitled "How America Took Out The Nord Stream Pipeline", Hersh said a plan was hatched in 2021 at the highest levels in the United States to destroy the pipelines. Russian Foreign Minister Sergei Lavrov said earlier this month that Washington was directly involved in the sabotage of the pipelines. Deputy Foreign Minister Sergei Ryabkov said there would be "consequences" for Washington, adding the report was not a surprise for Russia as it had long considered the United States and possibly other NATO members were behind the blasts. The United States should pay "compensation to countries affected by the terrorist attack", Volodin added.
A video of a building demolition in the Saudi city of Jeddah has been mistaken on social media for a building collapsing during an earthquake in Turkey. In the brief clip, a building is seen collapsing next to a busy road. But the video can be traced back on social media to at least January 2023, weeks before the earthquake (here). Its exact location can also be pinpointed to Old Mecca Road in Jeddah, Saudi Arabia (see bit.ly/3I8Vz2c and the same location on YouTube here ). The video can be traced back to at least January 2023 in Saudi Arabia.
“Earthquake (Turkey) - Visible Lateral Ground Movement…”, a Facebook user said in a caption alongside the video on Feb. 6 (here ). The CCTV video, dates from at least 2015 and has also been shared online in relation to the Nepal earthquake in April that year. The video was also posted to YouTube on June 1, 2015 with the headline “Nepal Earthquake - Visible Lateral Ground Movement” (here ). Video does not show earthquake in Turkey but dates from at least 2015. It has previously been shared in connection with an earthquake in Nepal on April 25, 2015, a reverse image search revealed.

[1/2] A damaged vehicle is seen on top the rubbles after an earthquake in Iskenderun, Turkey February 6, 2023. The epicentre was about 26 km east of the Turkish city of Nurdagi at a depth of about 18 km on the East Anatolian Fault. During the 20th century, the East Anatolian Fault yielded little major seismic activity. But in 1822, a 7.0 quake hit the region, killing an estimated 20,000 people. The East Anatolian Fault is a strike-slip fault.

ATHENS, Dec 28 (Reuters) - A 4.9 magnitude earthquake shook the island of Evia in central Greece on Wednesday and was felt in Athens, according to the Athens Geodynamic Institute. The tremor, with a depth of about 10 kilometres, struck around 1224 GMT in the wider area of Messapia. "It was felt very strongly... and lasted long," Messapia Mayor George Psathas told Skai radio. Seismologists told Greek media that the area had been hit by earthquakes about 20 years ago. Greece is often rattled by earthquakes, most causing no serious damage.
Investigators found traces of explosives at the site of the damaged Nord Stream pipeline in the Baltic sea, confirming that the pipelines had been subject to “gross sabotage,” the Swedish Security Service said Friday. The statement did not expand on how the explosives might have got there and said an investigation was ongoing. The Swedish statement confirmed preliminary findings by Swedish and Danish authorities in October that “powerful explosions” had caused damage to the Nord Stream pipelines, referring to ruptures in the pipeline in Denmark’s exclusive economic zone. Underwater blasts ruptured the Nord Stream pipelines, which carry natural gases from Russia to Germany under the Baltic sea, in late September. Russia and Norway are the two major European exporters of natural gas, upon whom the rest of Europe has long been dependent.
STOCKHOLM, Nov 18 (Reuters) - Investigators have found traces of explosives at the site of the damaged Nord Stream pipelines, confirming that gross sabotage had taken place, a Swedish prosecutor said on Friday. Swedish and Danish authorities are investigating four holes in the Nord Stream 1 and 2 pipelines which link Russia and Germany via the Baltic Sea and have become a flashpoint in the Ukraine crisis. Denmark last month said a preliminary investigation had shown that the leaks were caused by powerful explosions. "Analysis that has now been carried out shows traces of explosives on several of the objects that were recovered," the Swedish Prosecution Authority said in a statement. A section measuring at least 50 metres (164 feet) is missing from Nord Stream 1, Swedish daily Expressen reported on Oct. 18 after filming what it said were the first publicly released images of the damage.
SummarySummary Companies Russia says UK navy personnel blew up pipelinesRussia says UK navy personnel helped attack CrimeaRussia does not give evidence for claimBritain denies Russian claimsLONDON, Oct 29 (Reuters) - Russia's defence ministry said on Saturday that British navy personnel blew up the Nord Stream gas pipelines last month, a claim that London said was false and designed to distract from Russian military failures in Ukraine. "To detract from their disastrous handling of the illegal invasion of Ukraine, the Russian Ministry of Defence is resorting to peddling false claims of an epic scale," it said. Russia has previously blamed the West for the explosions that ruptured the Russian-built Nord Stream 1 and Nord Stream 2 pipelines on the bed of the Baltic Sea. PIPELINE MYSTERYSweden and Denmark have both concluded that four leaks on Nord Stream 1 and 2 were caused by explosions, but have not said who might be responsible. The Nord Stream 1 and Nord Stream 2 pipelines have a joint annual capacity of 110 billion cubic metres - more than half of Russia's normal gas exports volumes.
NASA's InSight lander felt a powerful Mars quake. Then an orbiter took a picture of the meteor impact that caused it. The impact kicked up boulders of water ice, which will be crucial for future astronaut missions to Mars. "It was immediately clear that this is the biggest new crater we've ever seen," Ingrid Daubar, InSight impact science lead, said in a press briefing.

Finnish seismologists detect five blasts in Russian waters

HELSINKI, Oct 25 (Reuters) - Finnish seismologists detected five underwater blasts in Russian waters in the Baltic Sea last week, the Helsinki University Institute of Seismology said on Tuesday. Four explosions were recorded on Thursday and one on Friday in Russian territorial waters in the Gulf of Finland, Tiira said, adding it had been clear that the observations had been caused by blasts and not by other seismic activity. "It can be seen in the shape of the signal and in the content of its frequency," he said. The institute did not know what had caused the blasts but that similar disturbances had been detected during previous naval drills and sweeping of old mines from the sea bottom, Tiira said. "We have detected explosions in that same area before, but not very often, not even every year," he said.
Russia's foreign ministry said on Thursday it was "unthinkable" that an investigation into ruptures on the Nord Stream 1 and 2 gas pipelines would proceed without Moscow's participation. President Vladimir Putin said on Friday the United States and its allies blew up Nord Stream. U.S. President Joe Biden said on Friday damage to Nord Stream was a deliberate act of sabotage.

BORNHOLM, DENMARK - SEPTEMBER 27: Danish Defense shows the gas leaking at Nord Stream 2 seen from the Danish F-16 interceptor on Bornholm, Denmark on September 27, 2022. Spanish Energy Minister Teresa Ribera said Thursday that the damage caused to the two subsea Nord Stream gas pipelines was likely an intentional attack linked to the Russian government. The cause of the gas leaks is not yet known. The Nord Stream 1 and 2 gas pipelines connect Russia to Germany via the Baltic Sea. Seismologists on Monday reported explosions in the vicinity of the unusual Nord Stream gas leaks, which are situated in international waters but inside Denmark's and Sweden's exclusive economic zones.
Russia intends to call a United Nations Security Council meeting over damage to the gas pipelines, Foreign Ministry spokeswoman Maria Zakharova said in a statement on Telegram. In the Baltic Sea, gas was still bubbling from the Nord Stream 1 pipeline, the Swedish Coast Guard said in an email. "There are good teams in place to handle pipeline accidents, there are emergency pipe inventories and experts for onshore and offshore," Jens Schumann, managing director of gas pipeline grid company Gasunie Deutschland, said. European gas prices rose following news of the leaks. The new Nord Stream 2 pipeline had yet to enter commercial operations.
"Any deliberate disruption of European energy infrastructure is utterly unacceptable and will be met with a robust and united response," Borrell said. A statement issued by Russia's embassy in Denmark said that any sabotage on Nord Stream's pipelines was an attack on both Russia's and Europe's energy security. Map of Nord Stream pipelines and locations of reported leaksGAS FLOWSOperator Nord Stream has called the damage "unprecedented", while Gazprom (GAZP.MM), the Russian-controlled company with a monopoly on its gas exports by pipeline, declined to comment. Russia reduced gas supplies to Europe via Nord Stream 1 before suspending flows altogether in August, blaming Western sanctions for causing technical difficulties. The new Nord Stream 2 pipeline had yet to enter commercial operations.
Sabotage was behind underwater explosions that sent gas spewing from two major pipelines connecting Europe and Russia, Western leaders concurred Wednesday. NATO Secretary General Jens Stoltenberg said he discussed the “sabotage” of the pipelines at a meeting with Denmark’s defense minister in Brussels. The incident has put the region on edge, months after fears of a Russian military threat to the Baltics dissipated in the wake of its military’s struggles in Ukraine. A new Baltic pipeline allowing gas to be delivered from Norway through Denmark to Poland was inaugurated Tuesday. In recent weeks, Moscow has increasingly framed the war as not just with Ukraine but its Western backers, too.
CNN —Leaders of several Western countries have said leaks in two Russian gas pipelines are likely the result of sabotage, vowing a strong response as investigations continue. “The destruction that occurred on the same day simultaneously on three strings of the offshore gas pipelines of the Nord Stream system is unprecedented,” said the pipeline’s operator Nord Stream AG. The incident has sank any remaining expectations that Europe could receive gas via Nord Stream 1 before the winter, as gas prices soar and countries hunt for alternative energy supplies. Russia halted all gas supplies to Europe via Nord Stream 1 in August, blaming Western sanctions for causing technical difficulties – which European politicians say is just a pretext to stop supplying gas. The new Nord Stream 2 pipeline had not yet entered commercial operation.
London CNN —Western nations have said leaks in two Russian gas pipelines, Nord Stream 1 and 2, are likely the result of sabotage. What happened on the Nord Stream pipelines? Swedish authorities first sounded the alarm on Tuesday about leaks in the Nord Stream 1 and Nord Stream 2 pipelines – both of which run under the Baltic Sea near Sweden and Denmark. The two Nord Stream pipelines designed to transport Russian gas to the EU were years in the planning. The damage to the Nord Stream pipelines may spell an ignominious end for the 25-year project, at least for the near future.
A senior Ukrainian official called the incident a Russian attack to destabilise Europe, without giving proof. Neither pipeline was pumping gas to Europe at the time the leaks were found, but the incidents will scupper any remaining expectations that Europe could receive fuel via Nord Stream 1 before winter. Operator Nord Stream said the damage was "unprecedented".
