A powerful earthquake struck near Iran's Semnan, sending tremors through the region. According to reports from the GFZ, a magnitude 5.2 earthquake occurred around 35 km southwest of Semnan at 5.49 local time. The earthquake's depth was recorded at 10 km, indicating a relatively shallow tremor that could possibly cause major damage.

As news of the earthquake spreads, concerns are growing about the potential impact on the region. Semnan, a city in northeastern Iran, is known for its rich history and cultural importance. The earthquake's epicentre, located near the city, raises concerns about damage to historical sites and infrastructure. While details about injuries or damage are still emerging, the region's vulnerability to seismic activity heightens the stakes.

Comment: Aaand the speculation is on that the quake was actually Iran testing a nuke. May voices of reason prevail

Hurricane Erick weakens after hitting Mexico's coast as Category 3 storm

nnnnnn
Hurricane Erick weakened after slamming into Mexico's southern Pacific coast as a Category 3 storm, leaving a trail of damaged businesses, wrecked boats and flooded streets in the state of Oaxaca as authorities warned of risks from heavy rain.

The hurricane struck near the beach town of Puerto Escondido in Oaxaca state early on Thursday morning, bringing powerful winds and rain. The storm was downgraded to Category 1 after landfall, with sustained winds dropping to 137 kilometres per hour (85 miles per hour).

In Puerto Escondido, emergency workers and residents moved quickly to restore access by removing fallen trees, downed signs and sand-covered boats. Streets were flooded, and large parts of the town lost power and mobile coverage.

Despite the destruction, officials reported no deaths or injuries in the storm's wake.

The government deployed hundreds of troops and electricity workers for the cleanup operation, the AFP news agency reported.

Luis Alberto Gil, a 44-year-old local shopkeeper, told AFP the floodwaters had reached levels unseen in recent memory. "The water had never hit with this magnitude," he said, standing outside his damaged business.

Tornadoes hit Saskatchewan as severe storms pelt Prairies

Tornado hits Saskatchewan as severe storms pelt Prairies
Storm spotters witnessed at least one tornado in southern Saskatchewan on Thursday as severe thunderstorms hit the region.

A dynamic setup across the south-central Prairies allowed isolated thunderstorms to develop on Thursday. The bulk of the active weather unfolded across Saskatchewan.

At least three rotating thunderstorms prompted tornado warnings from communities near Saskatoon to rural areas near Estevan.

The storm in southeastern Saskatchewan near Estevan produced at least one spotter-confirmed tornado. Multiple chasers in the region caught photos of the twister as it swept through fields, hurling debris through the air along its track.

Large hail, gusty winds, and heavy rainfall also accompanied the severe thunderstorms.

Experts will likely survey the damage in the days ahead to confirm the number of tornadoes that touched down Thursday and assign damage ratings on the Enhanced Fujita Scale.

A serial derecho ripped across the Ohio Valley on Wednesday and produced damaging wind gusts across hundreds of communities, causing nearly 500,000 power outages at the height of the storm.

According to the FOX Forecast Center, the derecho - a cluster of thunderstorms that produces multiple wind gusts of at least 75 mph - swept across a 580-mile stretch from Illinois to western Pennsylvania.

The states of Indiana, Illinois and Ohio appeared to be the hardest hit, with even a few tornadoes spotted during the late-morning and early afternoon.

Damage consistent with an EF-1 tornado was reported in Pike County, Missouri, according to the National Weather Service. A survey of the damage is ongoing.

Italy: Mount Etna erupts again with ash cloud up to 6,000 meters high

bbbbb
Mount Etna has erupted again on the Mediterranean island of Sicily. According to the Italian Institute of Geophysics and Volcanology (INGV), lava flows and an ash cloud up to 6,000 meters high were observed on Europe's largest active volcano.

Etna, which is around 3,350 meters high, erupts regularly and is constantly monitored. These so-called strombolian eruptions - explosive eruptions with lava and ash - often provide spectacular images and attract numerous spectators.

Highest warning level for air traffic - civil defense warns

According to the INGV, the ash cloud is mainly spread to the north. The lava escaping from the south-east crater flows into a small lava flow in the remote Valle del Leone ("Lion Valley"). Visibility of the activity is limited due to dense clouds.

At least 22 whale carcasses have been confirmed in the San Francisco Bay Area so far in 2025, including 19 gray whales (Eschrichtius robustus), two unidentified baleen whales, and one minke whale. This is the highest number reported in the region since 2021, when an Unusual Mortality Event (UME) affected gray whales along the Eastern North Pacific.

Data collected by local observers and the Marine Mammal Center indicate that more than 30 gray whales have been seen alive in San Francisco Bay over the same period. This represents an increase from just 6 whales observed by May 2024.

Approximately one-third of those whales remained in the bay for more than 20 days, with visible signs of varied health that ranged from normal to emaciated condition.
