Another earthquake recorded in Maine
Feb. 18—Another earthquake was recorded in Maine, but this one was more than 250 miles from the quake that rocked southern Maine last month.
The 2.5 magnitude earthquake at 8:56 p.m. Sunday was centered 21 miles northwest of Millinocket. Its recorded depth was about 6.6 miles.
The U.S. Geological Survey says four people reported feeling the earthquake.
The impact was much less significant than the 3.8 magnitude earthquake on Jan. 27 that was felt as far north as Bangor and south as New York City. That quake, centered 6 miles southeast of York Harbor, generated widespread reports from people who thought the audible boom and shaking were from an explosion or crash.
More than 42,000 people submitted reports about their experience to the geological survey.
That earthquake was followed by a couple aftershocks with magnitudes around 2.0.
While Maine doesn't typically have strong earthquakes, it is not uncommon for microquakes with a magnitude of less than 2.0 to occur. Most earthquakes in Maine are too small to be felt because the state is a quiet tectonic area, State Geologist Ryan Gordon, who runs the Maine Geological Survey, said last month.
The largest earthquake recorded in Maine was a magnitude 5.7 near the Canadian border in 1904. In 1929, a magnitude 7.2 earthquake off Newfoundland caused a tsunami and a few deaths, Hough said.
The last earthquake centered in Maine with a magnitude of 4.0 or greater was in October 2012. That magnitude 4.7 earthquake, with an epicenter in York County, was felt as far away as Connecticut and prompted concerned residents to overwhelm local 911 centers.

Washington DNR sends 200 firefighters to help with Canada wildfires
The Washington Department of Natural Resources (DNR) is sending more than 200 firefighters to Canada to help battle large wildfires in Alberta and Saskatchewan. It's part of the agency's Northwest Wildland Fire Protection Agreement with Canada. 'Wildfires and climate change don't recognize borders, which is why it's critically important we're able to provide our neighbors the certainty we'll be there to help when they need it most,' Commissioner of Public Lands Dave Upthegrove said. 'With only a line on a map separating Washington from Canada, I'm proud to have a team who can quickly respond to help our neighbors in Alberta and Saskatchewan in the same way Canadian firefighters have helped us with fires in the Okanogan or North Cascades.' DNR has sent eight contracted 20-person hand crews, a DNR 20-person hand crew, a DNR 10-person hand crew, one DNR strike team of engines, and leadership personnel. 'This is a great example of why regional compacts and state-to-state agreements are such a vital part of wildfire suppression preparation and response,' said George Geissler, DNR's State Forester and Deputy Supervisor responsible for Wildland Fire Management. 'We have a strong working relationship with Canada, which sent aircraft to assist on a fire on the Washington side of the border just last month. Now it's our turn to lend a helping hand.' DNR says it remains fully staffed and prepared to respond to any fires that pop up across Washington state. Wildfire season typically ramps up during July and August. According to DNR, nearly 90 percent of Washington wildfires are started by human activity.

Map Shows 2 States Where Children Warned of Breathing Difficulties
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Air quality alerts continued on Tuesday, with children in two states being warned of "breathing difficulties" if they are exposed to poor air quality. Weather conditions such as light winds and higher temperatures are causing smoke from Canadian wildfires to settle in Ohio, pushing air quality into the unhealthy range, National Weather Service (NWS) observing program leader Brian Mitchell told Newsweek. Why It Matters Smoke from Canadian wildfires prompted widespread air quality alerts across the Upper Midwest, Great Lakes, and Northeast regions over the past few weeks. As of Tuesday, most of the smoke has moved out of the region. However, air quality alerts remain in parts of Ohio and Arizona for fine particulate matter and ozone pollution, respectively. The Air Quality Index (AQI) is expected to be Unhealthy for Sensitive Groups, which includes children and the elderly, in the affected regions. What to Know When inhaled, particles can lodge deep in the lungs and trigger inflammation, while ozone irritates the respiratory system and can exacerbate asthma. Children are particularly vulnerable to the impacts because of their developing respiratory systems and tendency to spend more time outdoors. In Ohio, the air quality alert was issued by the Northeast Ohio Areawide Coordinating Agency and warns of ground-level fine particles affecting the air quality in Ashtabula, Cuyahoga, Geauga, Lake, Lorain, Medina, Portage and Summit Counties.

If you are in the sensitive groups category of children, the elderly and those with breathing difficulties, please monitor your outdoor activity and check air quality readings at In Arizona, an Ozone High Pollution Advisory was in place for Maricopa County, including more than a million people who live in the Phoenix metropolitan area. Sunlight can contribute to higher ozone levels, making these alerts more common in the summertime. "This means that forecast weather conditions combined with existing ozone levels are expected to result in local maximum 8-hour ozone concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates," the alert said. "Ozone is an air contaminant which can cause breathing difficulties for children, older adults, as well as persons with respiratory problems. A decrease in physical activity is recommended." In both states, people were urged to avoid worsening air quality levels by driving less, not idling in their vehicles, refilling their gas tanks after sunset, and waiting to mow the lawn. An air quality alert also was in place for parts of Michigan, although people in that state were not warned of breathing difficulties. What People Are Saying Air quality alert in Arizona: "You are urged to car pool, telecommute or use mass transit. The use of gasoline-powered equipment should be reduced or done late in the day." Air quality alert for Michigan: "Surface temperatures well into the 80s, ample sunlight, and west-southwest winds will create a conducive environment for Ozone development along the Lake Michigan shoreline. Residual wildfire smoke in the region may also enhance Ozone development over Lake Michigan." What Happens Next Both alerts are in place throughout Tuesday. More air quality alerts could be issued as smoke is expected to return on Wednesday.

‘When our mates need help, Australia is there'; Canada gets help fighting wildfires
As wildfires continue to burn from northwest Ontario to British Columbia, Canada is getting help from near and far, and very far. Southern Highlands - New South Wales Rural Fire Service in Australia says a 96-personnel-strong Australian contingent of firefighters and specialists have deployed to Canada for five weeks. The service says the deployment is in response to a request from the Canadian Interagency Forest Fire Centre. Australian Prime Minister Anthony Albanese says in a tweet that, 'When our mates need help, Australia is there.' A post on social media platform X from the official account for the Australian High Commissioner to Canada, Kate Logan, says the crews 'are on their way to support their Canadian colleagues battle wildfires in Alberta.' In Manitoba alone, the number of evacuees from fires has reached 21,000, and crews have come from other provinces and the United States. 'Thank you to our brave Aussie firefighters heading to help battle the Alberta wildfires in Canada. Stay safe and thank you for your service,' Albanese said on the social media platform X on Monday. Australia also sent firefighters to Canada in 2024 to help fight a massive blaze that forced the evacuation of Jasper National Park, as well as other fires earlier that month in British Columbia. The Yukon government, meanwhile, says it is sending 20 sustained-action firefighters to fight wildfires in Alberta and will be there for nearly three weeks. Thousands also remained out of their homes in Saskatchewan and Alberta, including between 10,000 and 15,000 in Saskatchewan alone. In British Columbia, the provincial wildfire service said Monday that crews were preparing for 'extreme fire behaviour' in the province's northeast as a second dry cold front was forecast to move through.
