'We're as active as California': What everyone needs to know about this week's earthquakes in NJ Experts say you shouldn't worry about the big one.

New Jerseyans may not realize they live on fault zone, making region susceptible to earthquakes. Not a single fault, but a lot of parallel faults. When you break something, you might get a lot of fractures and splinters...that's also what the Earth does, says LDEO's James Davis. Via @gothamist.com.

Canadian wildfires are impacting air quality in the U.S. Canada is having its second worst wildfire season yet. Two scientists explain what a red air alert means and how anyone living in impacted areas can protect themselves.

In the past, emissions from power plants or vehicles were bigger drivers of bad air quality. Now, wildfires are pretty much the whole story when it comes to air quality problems in the US, says @lamont.columbia.edu climate scientist @dwesty.bsky.social. Via @npr.org.

Students at Columbia Climate School in the Green Mountains conducting water chemistry sampling to assess the current health of local waterways and examine how climate change might impact water quality and ecosystem stability.

This summer, high school students attending Columbia Climate School in the Green Mountains explored "global weirding"—abrupt swings between extremes—and how climate impacts vary by contexts, gaining skills to help build resilience in their own communities: news.climate.columbia.edu/2025/08/06/a...

Leveraging Next-Generation Tsunami Early Warning Systems to Save Lives Tsunami early warning systems save lives not just when they are fast or accurate, but when they are trusted, understood and acted upon.

Days after small tremor rattles NYC area, USGS reports 2.7 earthquake in northern NJ Did you feel it? An earthquake with a magnitude of 2.7 was reported in northern New Jersey, according to preliminary information from the United States Geological Survey. The epicenter was registered ...

"It's important for us to increase earthquake/geo-hazard education, increase our understanding of the process and the systems, do more monitoring and support monitoring activity," says @lamont.columbia.edu structural geologist Folarin Kolawole. Via @nbcnewyork.com.

Another small earthquake in New Jersey rattles New York City, parts of the Tri-State area Another small earthquake appears to have been felt by a large number of people in the New York City region, according to posts on social media.

"It's not that rare and one thing that we do have that's quite different than out West is our crust is very old, so we feel earthquakes more intensely and from farther away for a given size," says Lamont geodesist James Davis. Via @abc7ny.bsky.social.

NYC could face $4.7B in damage if rocked by earthquake similar to recent temblors “What makes it different for New York City is there’s just a lot of infrastructure. So even a relatively low magnitude earthquake could have the possibility for some damage.”

Every earthquake should be a reminder of how important it is to adhere to safe building standards and to continue studying the seismology of the area, says @lamont.columbia.edu geodesist James Davis. Via @nypost.com.

Flash flood warnings are up in the US this year — Here’s where The 3,722 flash flood warnings that occurred between Jan. 1 and July 30 are a record high for the time period going back to 1986.

Warming atmosphere combined with factors like socioeconomic conditions, land use, and land cover increase the risk of flash floods, which will continue to grow and evolve in the coming years, says @ncdp.bsky.social climate scientist @wxpizza.bsky.social. Via @wvtm13.bsky.social.

How We Move Forward: A Chat with Climate School Professor Sheila Foster A Q&A with the accomplished legal scholar and educator known for her pioneering work on environmental and climate justice.

Professor of climate @sheilarose.bsky.social shares how law became her tool for justice, what the environmental justice movement is facing, and why she still finds hope in local action. On Aug 6, hear Foster speak as part of Harlem Week's Climate & Environmental Justice: A Discussion of NYC’s Plans.

In the third of seven science-led expeditions to uncover the spread of microplastics and nanoplastics in the world's most remote locations, Mission Spiritus traveled to the Faroe Islands. Led by polar explorer Alan Chambers, with scientific direction from Lamont-Doherty Earth Observatory environmental geochemist Beizhan Yan and climate scientist Maureen Raymo (pictured here), the team collected water, sediment, and air samples for research on the impact of plastics on human and environmental health.
