Hongkongers feel mild tremors as magnitude 5.6 quake strikes Philippines
Hongkongers reported feeling mild tremors that lasted for a few seconds on Tuesday morning after a magnitude 5.6 earthquake struck the Philippines, according to the city's weather forecaster. The Hong Kong Observatory said it had received more than 10 locally felt reports, adding that an initial analysis suggested the quake occurred in Luzon at 10.38am, with the epicentre located about 6km (3.7 miles) east of Laoag City. The focal depth is approximately 10km. It also said the tremor reported in Hong Kong had a local intensity of II on the Modified Mercalli Intensity Scale, meaning it would be felt by people at rest, on upper floors, or who were favourably placed.

5.2 magnitude earthquake strikes San Diego County, felt across Southern California
A 5.2 magnitude earthquake shook San Diego County and large parts of Southern California on Monday. The temblor was centered three miles south of Julian and 17 miles east of Ramona and was felt across the region. There were no immediate reports of major damage or injuries but some residents reported feeling a strong jolt. San Diego County firefighter Jarrett Ross, who was working at the agency's Julian station Monday morning, said they all definitely felt the quake but said it was "nothing too crazy." He said the station hasn't gotten any calls for injuries or damage since the earthquake. "It was just a long one, probably five seconds long or so," Ross said. He said nothing fell or became dislodged in the station due to the quake. Some people on social media told the U.S. Geological Survey that they got an earthquake early warning — fueled by the ShakeAlert system — on their cellphones. 'That was awesome! GREAT EARLY WARNING!!!' a resident told the USGS' ShakeAlert social media account on X. 'I got the alert on my phone near downtown San Diego several seconds before the primary [shaking] wave hit. WELL DONE!' The strongest shaking was in sparsely populated areas, considered 'strong' on the Modified Mercalli Intensity Scale. That's enough to be frightening and move furniture but generally causes only slight damage. In more heavily populated areas closer to the San Diego County coast, the U.S. Geological Survey said 'light' shaking was likely, capable of rattling dishes and feeling like a heavy truck has struck a building. The quake struck at 10:08 a.m. near Julian, an old mining town in the Cuyamaca Mountains that is about 138 miles southeast of Los Angeles. According to the U.S. Geological Survey, the quake was felt well into Los Angeles County and south to the Mexican border. It was followed by several aftershocks in the surrounding area, which is sparsely populated. Times staff writer Richard Winton contributed to this report.

4.1 earthquake felt across Southern California, centered near Malibu
A magnitude 4.1 earthquake centered north of Malibu sent light and weak shaking across Southern California Sunday. The strongest shaking was felt in parts of Malibu, Agoura Hills, Thousand Oaks and Camarillo, according to the U.S. Geological Survey. The strongest shaking was considered 'light' as defined by the Modified Mercalli Intensity Scale — enough to rattle dishes and windows and feel like a truck has struck a building. 'Weak' shaking may have been felt across a wider swath of the Southland, including downtown Los Angeles, Long Beach, the San Gabriel Valley, the Santa Clarita Valley, Simi Valley, Oxnard and Ventura. The earthquake hit on Sunday at 1:03 p.m. It was followed by a magnitude 2.5 earthquake a minute later, and a magnitude 3 and magnitude 2.8 aftershocks at 1:07 p.m. There were no immediate reports of damage. According the USGS. the light quake was felt across the region, from Goleta south to Huntington Beach. The epicenter was in the Santa Monica Mountains, about 3 miles northwest of El Matador State Beach and 3.5 miles northeast of Leo Carrillo State Beach. The epicenter was 7 miles southwest of Thousand Oaks and Westlake Village. In Westlake Village, people felt a roll and shake over about 5 seconds. Residents in Reseda felt a steady shake. In Redondo Beach, the shaking felt like a long rumble; in Windsor Hills, the quake felt like a long, slow roll. Someone in Torrance felt two jolts, and near Los Angeles International Airport, the earthquake felt like a brief sway. One person in downtown L.A. felt a long but gentle shake. An official at L.A. County Fire Station 88 on Malibu Road said no reports to damages have come in, adding "the guys here didn't even feel it." An official at Fire Station 99 on Pacific Coast Highway said it was felt but the station got no reports about damages. Southern California has been experiencing a number of moderate earthquakes since 2024. As of mid-November, Southern California had experienced 15 seismic sequences with at least one magnitude 4 or higher earthquake during the first 11.5 months of 2024, according to the count of seismologist Lucy Jones, a Caltech research associate. That's the highest annual total in the last 65 years, surpassing the 13 seen in 1988. Sign up for Essential California for news, features and recommendations from the L.A.

Magnitude 3.9 earthquake rattles Burbank and LA, US
Listen to article A magnitude 3.9 earthquake centred in Burbank sent light shaking across the Los Angeles region on Sunday night, with no reports of significant damage or injuries. The earthquake struck at 10:13 p.m. and was felt most strongly near the epicentre, located along the 900 block of North Ford Street in Burbank, according to the US Geological Survey (USGS). The shaking, classified as "light" on the Modified Mercalli Intensity Scale, caused minor disturbances such as rattling dishes and windows, and was likened to the impact of a heavy truck hitting a building. The tremors were felt across a broad area, including the San Fernando Valley, the Los Angeles Basin, and the San Gabriel Valley. Local authorities in Burbank reported feeling the earthquake but confirmed there were no immediate calls for assistance or signs of damage. The earthquake occurred at a depth of 9.5 miles, about one mile from Los Angeles, two miles from Glendale, and four miles from both Beverly Hills and West Hollywood. This tremor adds to a history of smaller earthquakes in the region, with an average of five quakes of magnitude 3.0 to 4.0 reported annually in Greater Los Angeles. On the other hand, firefighters in North and South Carolina battled dozens of wildfires over the weekend, with dry and windy conditions prompting authorities to issue evacuation orders and declare a state of emergency. South Carolina Governor Henry McMaster declared the state of emergency on Sunday as wildfires continued to rage across the state. Officials had previously declared a statewide burn ban, which McMaster confirmed would remain in effect indefinitely due to the critical fire weather conditions. One of the most significant fires, the Carolina Forest Fire near Myrtle Beach, S.C., has scorched around 1,600 acres. By Sunday evening, the fire was 30% contained, and residents were allowed to return home. In North Carolina, officials also issued evacuation orders in response to the 176 Fire in the Blue Ridge Mountains. The fire had burned over 500 acres by Sunday evening and was also 30% contained. Evacuations were expected to continue, with a decision on lifting orders scheduled for Monday. The National Weather Service warned that the dry, windy conditions were contributing to critical fire weather across the region. Fire weather concerns were also reported across eastern New Mexico and far western Texas, where the NWS issued further warnings for gusty winds coupled with dry conditions.
