- Description
- A winter of heavy rain causes flooding in California's Tulare Basin, threatening cropland. The basin was once the site of a large lake that appeared naturally every winter as rainfall and snowmelt from the nearby Sierra Nevada mountain range flowed down and filled the basin. It was even known as the largest lake west of the Mississippi River.
But more than a century ago, when irrigation systems were developed to water area crops, the spring runoff wasn't enough to reach the basin anymore, and it dried up. This winter's heavy rains are filling it up again, and the snow has yet to melt from the mountaintops. A series of images from Landsat show the extent of the floodwaters in dark blue or black.
Growing vegetation appears green, revealing gridded farm fields. Tan-colored fields show bare soil where nothing is growing. Landsat satellites continue to provide valuable monitoring for water levels and potential flooding around the world.

Much of what we know about fish as food, we’ve learned through studying large-scale commercial fishing operations. But most people interact with fish in much smaller settings, for example by fishing in their local streams and lakes. Research Fish Biologist Holly Embke with the Midwest Climate Adaptation Science Center studies how climate change is impacting inland fish populations and how managers can develop climate-informed strategies to maintain healthy fisheries. She works with both subsistence and recreational communities to help develop management strategies that will support resilient fisheries in a changing climate.

Many of Alaska’s watersheds are defined by the icy glacial meltwaters that re-charge the rivers and streams each spring. But climate change is causing glaciers to melt at unprecedented rates, fundamentally altering the way water moves through Alaskan ecosystems. Jeremy Littell, Research Ecologist with the Alaska Climate Adaptation Science Center, is exploring how changing glacial landscapes in Alaska are affecting one of the area’s most valued species: salmon. His work combines hydrology and ecology to understand how new climate and river conditions may impact cold-adapted salmon, and seeks to develop strategies for preserving salmon populations in the future.

- Research Ecologist Adam Terando helps people understand how climate change may affect their communities and ecosystems by using mathematical models to “downscale” large global climate models.
Global climate models use physics to model atmospheric processes, allowing scientists to predict how climate change may affect future temperature and precipitation patterns. Yet due to limitations in computing power and time, these models are often at very large spatial scales. This can make it difficult to make climate predictions for small, localized areas, as global models may only give one number for an entire island or national park containing many different ecosystems. Adam Terando, Research Ecologist with the USGS Southeast Climate Adaptation Science Center, uses a process called “dynamical downscaling” to generate climate model results at small, local scales. This helps managers to understand how climate change can impact different landscapes, elevations, and topograp...

Climate change affects each place, ecosystem, and species a little differently. This creates challenges for resource stewards tasked with managing systems that they know are changing, but don’t necessarily understand how. Brian Miller, Research Ecologist with the North Central Climate Adaptation Science Center, uses climate model outputs to help resource managers understand the possible range of “climate futures”. He leads managers through scenario planning exercises considering different possible future climate conditions in their area, asking questions like “What would you do if your national park became hotter and drier, versus warmer and wetter?” Through these discussions, managers can...

- Do animals prank humans? It sometimes feels that way, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland. Mike shows some of the ways animals have “interacted” with monitoring equipment in this April 1, 2023 monthly update of activity at Yellowstone Volcano.
Herds of elk or bison make a lot of noise when they walk by a monitoring station. The noise is picked up by the seismometer and the sudden burst of activity in a data feed might cause some to be concerned. Fortunately, that noise can be filtered out so seismologists will still see small earthquakes even when the herds are walking by. It's funny to think that maybe these animals are pranking us as they stomp around the station. Seismometers used for research deployments have been kicked by animals, making us wonder if perhaps the bison saw the seismometer and decided to play soccer with it.
Animals also interact with some of the permanent monitoring stations. Like humans, animals a...

- Description
- Cheyenne Bottoms is the largest inland wetland in the United States. Water normally diverts from rivers into the vast marshland. The wetland water level changes with precipitation and surface flows. For example, 2007 was a wet year. And 2013 was a dry year. Heavy rains in late summer typically replenish the water levels in the marshland, making it a key stopover for thousands of migrating birds to eat and rest. In the fall of 2022, the birds found nothing to stop for. Landsat images show not only the lack of water, but also an overall lack of healthy green vegetation due to drought conditions in the region.

- Could an external event trigger a Yellowstone eruption? No, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland, that’s not how volcanoes work. Most of the pressure that drives a volcano toward eruption comes from within, from the exsolution of gases in the magmatic system. External events, like large earthquakes or nuclear blasts can't cause that.
This question arose in 2019 after the magnitude 7.1 Ridgecrest earthquake in eastern California, and again in March of 2020 with the magnitude 6.5 in central Idaho. More recently, YVO has been asked if a nuclear blast could trigger a Yellowstone eruption.
Consider Yellowstone's history. The last lava flow eruption was 70,000 years ago, and there have been hundreds to thousands of magnitude 7, 8, 9 earthquakes in the western U.S. since that time without triggering an eruption. The last big explosion was 631,000 years ago, and again, there have been thousands of very large earthquakes in the wes...

- Description
- Winter has arrived in the Yellowstone region. The deep snow and cold temperatures are harsh for animals, harsh for humans, and also harsh for volcano monitoring equipment. To protect the instruments and keep data flowing, seismometers are buried, and solar panels and radio antennas are positioned high enough above ground to prevent them from getting covered in snow.
But the pole-like GPS antennas can become coated in ice during stormy weather. Once the antenna is covered, it can cause the signal to take a little longer to get to the antenna. So in the online data streams, the data might appear as though the ground went down, when really it was just ice on the antenna. When the ice goes away, the data pop back up to previous levels. Fortunately, there are so many GPS stations in the region that data from different sites can be used as a comparison to make sure the ground is not moving, and a quick check on the weather can confirm local conditions.

- Description
- This video, captured by the remote B1cam, shows lava erupting from multiple minor fountains (shown as a line of bright spots in the upper left of the video) and the cooling surface of the lava forming crustal plates that move toward the camera’s location. In the lower portion of the video, you can see lava stacking up at the margin to build levees, which has created a perched lava lake within the crater. Several lava overflows of the levee are also visible during this one-day time period.

- Description
- During the early morning hours of January 5, USGS Hawaiian Volcano Observatory scientists were closely monitoring an increase in earthquake activity and changes in the patterns of ground deformation at Kīlauea’s summit, indicating movement of magma in the subsurface. The geophysical signals intensified around 3 pm and HVO raised Kīlauea’s volcano alert level and aviation color code because an eruption was possible.
The remote B1 webcam, set up to view conditions within Halema‘uma‘u crater, showed steaming and then the dramatic opening of a new vent and lava erupting onto the crater floor at 4:34 pm HST on January 5, 2023.

- Description
- Kīlauea volcano began erupting in Halema‘uma‘u crater around 4:34 pm HST on January 5, 2023, as captured in this KWcam video. Within hours, multiple dome fountains were active in the central-eastern portion of Halema‘uma‘u crater’s floor. There were several large bursts of lava from the newly opened vent. One large burst up to 50 meters (164 feet) high occurred around 4:49 pm and sent a wave of lava across the crater floor.
The high initial effusion rates rapidly declined as lava stored within the magma system over the past month erupted. The lava fountains decreased in vigor overnight on January 5, reaching heights of about 5 meters (16 feet). By January 8, activity focused at one dominant dome fountain, bubbling in the central-eastern portion of the active lava surface.

- Description
- Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, provides an overview of 2022 events and December activity in this monthly update for January 1, 2023.
2022 was an average year for earthquake activity. About 2,500 earthquakes were located in the Yellowstone region, with over one-third of those being part of a single, long-lived swarm near Grizzly Lake, between Norris Geyser Basin and Mammoth Hot Springs. The area from Hebgen Lake to north central Yellowstone is the most seismically active area in the region, so it isn’t too much of a surprise that a swarm occurred there.
The largest earthquake of 2022 was a magnitude 4.2 that occurred in May in the eastern part of the park and was felt by many people in the Yellowstone region. There were a few magnitude three earthquakes, but the vast majority were magnitudes two and below.
Ground deformation trends continued. The caldera region continued to slowly subside by a couple of...
