NEW: After today's magnitude 7.7 quake off the Pacific coast of Japan, the country has issued a 'megaquake advisory', suggesting there's a 10x greater risk of a magnitude 8.0+ quake in the coming days.
I break down what this means for @sciam.bsky.social www.scientificamerican.com/article/risk...
NEW and EXCLUSIVE: Last week, @antea04.bsky.social / @ourworldindata.org launched a search for a cherry blossom observer in Japan, following the death laat year of Prof Yasuyuki Aono, who had worked on the data for decades.
They've found someone.

A M5.7 earthquake occurred in west-central Nevada yesterday evening - close to a very similar earthquake about one year earlier. Can we tell what faults they occurred on, and were they related?

A massive rupture on the Seattle fault, which runs right under the Seattle metro area, could threaten millions and cause billions of dollars of damage. But it’s not just the biggest quakes scientists are concerned about. 🧪 eos.org/articles/on-...

A 4.8 quake bucks the Ford Bronco at Timberline with scientists Richard Waitt and Barry Voight inside.
Fifteen minutes later, two miles down: a stop at Harry Truman's lodge.
"That earthquake's the granddaddy of them all," he tells the geologists. "Couldn't stand in the sonofabitch."
The #heatwave during March 2026 was unprecedented in the western U.S. temperature records since 1895. March 2026 average temperatures shattered records in Colorado (by 4.3ÂşF), Utah (by 5.5ÂşF), and Wyoming (by 2ÂşF).

USGS #Kilauea Update:
Despite the somewhat reduced intensity of tephra fall around KMC (near the park's Welcome Center) conditions remain hazardous: HVO field crew report tephra clasts up to softball-sized are still dropping.
#HVNP remains closed at Kilauea summit.
Low fountaining has begun at #KÄ«lauea Volcano:

And finally, Uncle Walter on the evening news.
You also get a glimpse of a young Don Swanson, USGS geologist and future Hawaiian Volcano Observatory and Cascades Volcano Observatory Scientist-in-Charge.
One of the scientists we'll be spending more time with in the weeks ahead.

You meant udderly?
For every 1°C of warming, the atmosphere can hold approximately 7% more moisture. Just sayin’.
California’s lowest snowpack since 2015 means water storage is below normal. Reservoir levels are above normal but the paltry snowpack (which normally accounts for ~30% of water storage in CA) is putting the Sierra Nevada millions of acre-feet short of normal

If you haven’t watched this before, you really should. The brilliant Dr. Carl Sagan testifying before the United States Congress in 1985 on #ClimateChange.
We should have listened then. Will we now?
Remember, climate change isn’t an on & off switch. It’s an exponential dial. We’re making it worse.
3/16/26 10:40 am:
Record-breaking high temps are forecasted for the next several days, which will substantially accelerate snowpack melt.
Given current melt and lack of #snow in the forecast, we may see melt-out as early as the first week of April, ~5 weeks earlier than normal.

March 15, 1980 a swarm of harmonic tremors is recorded at Mount St. Helens, Washington State. Such tremors coming from the deep underground can be a signal for rising magma and a potential future eruption...
Another anniversary. 15 years ago today, the M9.1 Tohoku earthquake and tsunami swept through northeaster Honshu, sweeping away whole towns and killing almost 18,000 people. Five years later, this town of Otsuchi was still struggling with what to allow to be rebuilt.
Yes! Science wins! Getting a siphon going can be very rewarding đź’¦
The third anniversary of the week. 100 years ago today, LADWP began impounding water at the San Fransquito Dam in northern LA County. Exactly 2 years later on 3/12/1928, the dam failed suddenly and catastrophically, releasing 47million cubic meters of water, killing 430+ people.
