Is New York earthquake prone? Recent quake and flood woes highlight city's complex natural risk profile
New York's earthquake risk is classified as 'intermediate' but significantly lower than California's due to its location far from active tectonic plate boundaries. Instead, the city and surrounding areas experience intraplate earthquakes caused by the reactivation of ancient faults within the North American plate, such as the Ramapo Fault system that stretches through New York, New Jersey, and Pennsylvania.The largest earthquake documented near New York City was a magnitude 5 event in 1884, likely between Brooklyn and Sandy Hook. Earthquakes of magnitude 5 or greater occur roughly once every 100 years, and smaller magnitude quakes have been recorded frequently enough to remind experts that seismic preparedness is warranted.Recent quakes in the area include a magnitude 4.8 tremor near Whitehouse Station, New Jersey in April 2024 and the recent 3.0-magnitude event in New Jersey, whose effects extended into Manhattan and Brooklyn. Despite these quakes being moderate, New York City's dense population and many buildings lacking modern seismic reinforcement (as most predate the 1995 seismic code) raise the possibility of structural damage even in moderate shaking scenarios.
New York City Emergency Management has monitored these events closely, advising residents to check for hazards after tremors and reminding that no significant damage was reported for the latest quake. FEMA ranks New York as having a notable risk for earthquake-related losses, particularly due to its aging infrastructure and unreinforced masonry buildings. Flash floods
Alongside seismic concerns, New York and its surrounding areas are currently battling severe weather conditions marked by intense rainfall and localized flooding. The city has faced repeated episodes of heavy downpours in the summer of 2025, overwhelming drainage systems and raising alarms for flood preparedness.
Meteorological data from early August 2025 indicates persistent storms fueled by humid air masses from the Atlantic, leading to flash flooding in low-lying neighborhoods and subway disruptions. The National Weather Service (NWS) has issued several warnings for the New York metropolitan area, advising residents to remain cautious of flooded roads and stalled traffic.Authorities urge residents to remain informed about both earthquake preparedness and flood safety measures as New York navigates these multifaceted natural risks.

Massive California wildfire grows, becomes state's largest in 2025
Rising temperatures on Wednesday posed new challenges for firefighters who have made incremental progress against a massive wildfire in central California that has injured four people as it has become the biggest blaze in the state so far this year. More than 870 remote homes and other structures at the northern edge of Los Padres National Forest are threatened by the Gifford Fire, which grew only slightly overnight after burning out of control for days. The fire has scorched at least 339 square kilometres of Santa Barbara and San Luis Obispo counties, with just 9 per cent containment. It surpassed the 326-square-kilometer Madre Fire, which erupted last month in southeastern San Luis Obispo County, as the state's largest fire of 2025. Crews working in steep, inaccessible terrain will be dealing with temperatures in the mid-90s (35 Celsius) on Wednesday and above 100 (38 Celsius) on Thursday, said Capt. Scott Safechuck with the Santa Barbara County Fire Department. We have hot weather, and we have low relative humidity, Safechuck said Wednesday. So we expect extreme fire behaviour. Luckily, winds are expected to remain relatively calm, he said. Wildfire risk will be elevated through the weekend across much of inland California as the heat wave intensifies. The southern part of the state has seen very little rain, drying out vegetation and making it ripe to burn, the National Weather Service for Los Angeles warned in a statement. Triple-digit temperatures (around 38 Celsius) are forecast for the Sacramento Valley. More than 2,200 personnel are battling the Gifford Fire, which grew out of at least four smaller fires that erupted Friday along State Route 166, forcing closures in both directions east of Santa Maria, a city of about 110,000 people. The causes of the fires are under investigation. Flames are racing through a vast, mostly unpopulated region that includes forestland, ranches, large canyon properties and agricultural parcels growing wine grapes and strawberries. The weather service warned of health risks from spreading smoke that could affect much of southwest California. Officials reported four injuries, including a firefighter who was treated for dehydration. Over the weekend, a motorist was hospitalised with burn injuries after getting out of his vehicle and being overrun by flames. And two contract employees assisting firefighters were also hurt when their all-terrain vehicle overturned.

US air quality alerts: New York, New Jersey, Pennsylvania among 9 states hit by Canadian wildfire smoke
National Weather Service has issued a series of Air Quality Alerts across the northeastern and midwestern United States for August 5 as wildfire smoke from Canada continues to drift southward, blanketing large swaths of the country in hazardous fine particulate matter (PM2.5). NWS said residents in New Jersey, New York, Connecticut, Pennsylvania, Massachusetts, Vermont, Michigan, Wisconsin, and Indiana have been warned to limit outdoor activity due to unhealthy air conditions, especially for sensitive populations. New Jersey, New York, and Connecticut all remain under Air Quality Action Days through midnight tonight. The New Jersey Department of Environmental Protection has flagged Bergen, Passaic, Hudson, Essex, and Union counties, while the New York State Department of Environmental Conservation extended the alert to all five NYC boroughs and counties north of the city including Westchester, Rockland, Orange, and Putnam. The Connecticut Department of Energy and Environmental Protection issued alerts for Fairfield, New Haven, and Middlesex counties until 11 PM. Across all states, officials are advising sensitive individuals — including children, older adults, and those with asthma, lung, or heart disease — to limit strenuous or prolonged outdoor activities. The New York State Department of Health echoed this concern, urging those at risk to consider consulting a physician if symptoms such as shortness of breath, wheezing, or chest discomfort develop. The Air Quality Index (AQI) values in affected areas are expected to exceed 100, placing many regions in the "Unhealthy for Sensitive Groups" category. Fine particulates (PM2.5), the primary pollutant, are microscopic particles that can penetrate deep into the lungs and bloodstream, exacerbating existing health issues and triggering new symptoms in vulnerable populations. States such as Michigan, Wisconsin, and Indiana reported direct impacts from Canadian wildfire smoke, particularly from fires in Manitoba and Ontario. High pressure systems have trapped smoke close to the ground, worsening air quality. In Michigan, counties across the northern and central parts of the state were affected, with concentrations expected to ease by Wednesday. Meanwhile, Wisconsin's Department of Natural Resources expects smoke to persist throughout the day, with heavier conditions in the northeast. Vermont: Counties of Bennington and Windham are under alert through midnight due to smoke-driven PM2.5 levels. Massachusetts: An alert is in effect from 11 AM to 11 PM for Fine Particulates. Pennsylvania: Issued a Code Orange Alert, indicating unhealthy air for sensitive groups, especially in urban centers. Indiana: Declared an Air Quality Action Day for fine particulates and advised reducing outdoor exposure. Officials across all regions recommend the following precautions: Avoid or limit outdoor exertion, especially if you're in a sensitive group. Keep windows closed and use air purifiers or HVAC systems with MERV-13 filters or higher. Avoid activities that worsen air quality, such as burning wood or refueling vehicles during the day. Monitor symptoms such as coughing, difficulty breathing, chest tightness, or eye irritation — and seek medical advice if they worsen. Check your local AQI at for real-time updates.

The storm is tracking north of Bermuda and is expected to transition into an extra-tropical system as it moves into the colder waters of the North Atlantic. Live Events Meanwhile, a tropical wave over Africa is projected to enter the eastern Atlantic this week, with a strong chance of developing into a tropical storm by late week. However, it remains far from Texas and is not expected to impact the region. Closer to the U.S., some lingering rain near South Carolina could also organize into a tropical storm later this week, though it too is not expected to affect Texas.
