Tectonic Plates Can ‘Infect' One Another with Earth-Shaking Subduction Zones
Subduction zones, where one tectonic plate dives underneath another, drive the world's most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents evidence that subduction can spread like a contagion, jumping from one oceanic plate to another—a hypothesis previously difficult to prove. This result 'is not just speculation,' says University of Lisbon geologist João Duarte, who was not involved in the research. 'This study builds an argument based on the geological record.' Because subduction drags crust deep into the earth, its beginnings are hard to examine. The new study provides a rare ancient example of potential subduction 'infection.' Its authors say they've discovered evidence that neighboring collisions triggered East Asia's 'Ring of Fire,' a colossal subduction system currently fueling earthquakes and volcanoes from Alaska to the southern Indian Ocean.

Nearly 300 million years ago China was a scattering of islands separated by the ancient Tethys and Asian oceans. Established subduction zones consumed these oceans, welding the landmasses into a new continent and raising mountains from Turkey to China. By 260 million years ago this subduction seems to have spread and begun pulling down the neighboring Pacific plate. 'The dying act of those closing oceans may have been to infect the Pacific plate and start it subducting westward under the Asian continent,' says study lead author Mark Allen, a geologist at Durham University in England. 'In one form or another, it's been diving down ever since.' The smoking gun in this case is the 'Dupal anomaly,' identified by a geochemical fingerprint from the ancient Tethys Ocean and what is now the Indian Ocean. When the study authors unexpectedly found this signature in volcanic rocks from the western Pacific, they surmised that material from the Tethys had spread eastward across a plate boundary from one subduction zone to another—triggering the neighboring plate's descent. 'It's like seeing someone's fingerprint at a crime scene,' Allen says. But the mechanism of spread remains mysterious. The researchers suspect that transform faults—boundaries where plates slide past one another, like the San Andreas Fault—may act as weak spots where slight changes in collision angle or speed can destabilize dense oceanic crust, causing it to sink. Duarte compares the scenario to aluminum foil in water. 'The foil floats,' he says, 'but the slightest tap will cause it to sink.' If subduction spreads this way, could the Atlantic Ocean 's relatively quiet plate margins be next? The massive 1755 Lisbon earthquake hints at early subduction invasion there. Duarte suggests parts of Iberia and the Caribbean are undergoing this process's initial stages: 'In another 100 million years a new Atlantic 'Ring of Fire' may form—just as it once did in the Pacific.'

Tethys Petroleum Announces Interim Results and Corporate Update
Grand Cayman, Cayman Islands--(Newsfile Corp. - May 29, 2025) - Tethys Petroleum Limited (TSXV: TPL) ("Tethys" or the "Company") today announced that it has filed its interim results for the three months ended March 31, 2025 with the Canadian securities regulatory authorities comprising its Audited Financial Statements together with Management's Discussion and Analysis and other required forms. Copies of the filed documents may be obtained via SEDAR at or on Tethys' website at Financial highlights Oil and gas sales increased by 104% to $4.0 million in the first quarter of 2025 from $1.9 million in 2024 due primarily to increased oil production. The net profit for the period was $.3 million compared with a loss of $1 million in 2024. Revenues for Q1 were improved from Q1 2024 but were disappointing relative to management expectations. Tethys received a production license in November 2024 after a period of being shut down. There are a number of factors which can influence the level of oil production. In addition to the limitation of the logistics and what is allowed under the production license (currently 485 tons/day), Tethys is required to have gas treatment for the associated gas. Tethys's model has been to sell the oil for delivery in the oil field and is therefore dependent on the oil buyers in terms of the logistics. The elimination of the export of naptha has damaged the overall profitability of the mini-refineries who have been the traditional purchases of Tethys oil. This appears to have not only impacted the price that Tethys can expect to receive but may have also impacted the ability of the mini-refineries to prepay for the oil and their ability to manage the necessary logistics. Given the remote location of the Kulbas field, an oil buyer needs to coordinate the trucking, the rail cars and coordinate with any rail terminal involved in the transshipment. The condition of the roads in March was a factor as the area went through a spring thaw as temperatures got above freezing. Given above average precipitation, it appeared the roads remained inoperable for a longer period than usual. While management believes the logistics issues have been largely resolved, a new problem has appeared. The ratio of gas per oil produced (the GOR) has increased. While long term getting gas from the oil production will be a positive, short term it is a negative as Tethys doesn't have the necessary facilities in place to treat the full amount of gas being produced. As a result, production rates have been reduced of late to about 250 tons/day so that Tethys won't have to flare the excess gas. While it is hoped that the high GOR level may drop back to previous levels or that certain wells and zones with lower GOR ratios may be enhanced to increase the oil production without increasing the GOR, there is no certainty in this regard. Tethys is working on plans to increase the gas utilization capacity of the Kulbas field so that production can be increased to the allowed levels. The delay in getting paid for its gas, getting a new gas contract and getting the oil production license have had residuary effects on the level of cash and the Tethys's ability to fund required capital expenses. Tethys through its DMS subsidiary is acquiring seismic on two of its exploration blocks. The acquisition for the seismic on Aral 4 has been recently completed and the seismic crew contracted for the work has moved to acquire the seismic on the Diyar block. The seismic will then be more fully processed and interpreted to identify potential sites to consider for exploration. DMS will then need to go through a permitting process to get regulatory approval before it can drill any well. If a favorable prospect and well site is developed, the goal is to drill the well(s) by the end of 2026. About Tethys Tethys is focused on oil and gas exploration and production activities in Central Asia and the Caspian Region. Tethys believes that significant potential exists in both exploration and in discovered deposits in the area. Disclaimer Some of the statements in this document are forward-looking.

Tethys Petroleum Annual Results and Corporate Update
Grand Cayman, Cayman Islands--(Newsfile Corp. - April 29, 2025) - Tethys Petroleum Limited (TSXV: TPL) ("Tethys" or the "Company") today announced that it has filed its Annual Results for the year ended December 31, 2024 with the Canadian securities regulatory authorities comprising its Audited Financial Statements together with Management's Discussion and Analysis and other required forms. Copies of the filed documents may be obtained via SEDAR at or on Tethys' website at Financial highlights Oil and gas sales decreased by 58% to $15.2 million in 2024 from $36.5 million in 2023 due to lower production volume and lower prices. The net loss for 2024 was $19.1 million compared with a profit of $9.7 million in 2023. The Group's results in 2024 were negatively impacted by two significant non-cash charges: an impairment of Kul-Bas contract area costs that were unrelated to the current Klymene field development and also by currency translation differences from depreciation of the Kazakhstan tenge against the US dollar. Management remains confident on the future of Tethys despite the delays experienced in the production license approval and the decline in oil and gas prices. Tethys has little to no debt and has valuable operating assets. While it will be a challenge to develop the oil handling, gas utilization, gas operations and logistics necessary to increase production, we remain confident that over time these challenges and requirements can be met. We appreciate the continued support and understanding of Tethys shareholders through a more challenging period and want shareholders to know that the board and management are doing what we can to create a good company and return on investment. About Tethys Tethys is focused on oil and gas exploration and production activities in Central Asia and the Caspian Region. Tethys believes that significant potential exists in both exploration and in discovered deposits in the area. Disclaimer Some of the statements in this document are forward-looking.
