1,000-year-old bones represent oldest tsunami victims in East Africa | National Geographic
Wednesday, May 13, 2020
A thousand years ago, a thriving early Swahili village bustled on the banks of Tanzania's Pangani River a few miles inland from the Inidan Ocean. Residents built their houses out of wood lattices daubed with earth. They filled their nets with fish and crafted beads from shells. And then one day, a tsunami barreled in, triggered by an earthquake on the other side of the Indian Ocean. Jody Bourgeois, professor emeritus of Earth and space sciences at the UW, is quoted.

Seismologists to host virtual event on 40th anniversary of Mount St. Helens eruption
Tuesday, May 12, 2020
The Pacific Northwest Seismic Network, based at the University of Washington, will host an online event on the 40th anniversary of the eruption of Mount St. Helens, featuring seismologists from the UW and other institutions who can explain the events before, during and after the historic blast.
The virtual event will take place from 6:30 to 8 p.m., Monday, May 18, on the PNSN's YouTube channel — exactly 40 years after the blast. The group will stream prerecorded talks from four speakers and then host a live Q&A of questions on the network's Facebook page. Moderator Harold Tobin, director of the PNSN and a UW professor of Earth and space sciences, will select audience questions.
Mount St Helens 40th Anniversary
- Attend the virtual event
- Read "After the Ashes" in UW Magazine’s March issue — an excerpt from "After The Blast: The Ecological Recovery of Mount St. Helens" published by UW Press
- View historical photos of Mount St. Helens from UW Libraries Special Collection
The presenters will review the region's tectonics, volcanoes and volcanic hazards, and summarize how the science and monitoring has evolved over the past four decades.
Steve Malone, research professor emeritus of Earth and space sciences, was intimately involved with recording and interpreting the earthquake buildup to the massive eruption. His personal story of the two months leading up to the 1980 eruption will illustrate the difficulty and uncertainty of dealing with a developing natural disaster in real time.
Seth Moran did his doctorate at the UW with Malone and is now scientist-in-charge at the U.S. Geological Survey's Cascade Volcano Observatory. He will describe the more recent activity at Mount St. Helens and the USGS work on volcano monitoring throughout the Cascades.
Jackie Caplan-Auerbach, a professor of geophysics at Western Washington University whose research focuses on volcanoes and landslides, will discuss plate tectonics and the origin of the Cascade volcanoes.
Josef Dufek, professor at the University of Oregon, will discuss the individual character of different volcanoes and volcanic hazards.

First results from NASA's ICESat-2 map 16 years of melting ice sheets
Thursday, April 30, 2020
Using the most advanced Earth-observing laser instrument NASA has ever flown in space, a team of scientists led by the University of Washington has made precise measurements of how the Greenland and Antarctic ice sheets have changed over 16 years.
In a new study published April 30 in the journal Science, researchers found the net loss of ice from Antarctica, along with Greenland's shrinking ice sheet, has been responsible for 0.55 inches (14 millimeters) of sea level rise to the global ocean since 2003. In Antarctica, sea level rise is being driven by the loss of the floating ice shelves melting in a warming ocean. These ice shelves help hold back the flow of land-based ice.
The findings come from the Ice, Cloud and land Elevation Satellite 2 (ICESat-2), which was launched into orbit in fall 2018 and began taking detailed global elevation measurements, including over Earth's frozen regions. By comparing the new data with measurements taken by the original ICESat from 2003 to 2009, researchers have generated a comprehensive portrait of the complexities of ice sheet change -- and insights into the future of Greenland and Antarctica.
"If you watch a glacier or ice sheet for a month, or a year, you're not going to learn much about what the climate is doing to it," said lead author Benjamin Smith, a glaciologist at the UW Applied Physics Laboratory. "We now have a 16-year span between ICESat and ICESat-2 and can be much more confident that the changes we're seeing in the ice have to do with the long-term changes in the climate. And ICESat-2 is a really remarkable tool for making these measurements. We're seeing high-quality measurements that carpet both ice sheets, which let us make a detailed and precise comparison with the ICESat data."
Previous studies of ice loss or gain often analyze data from multiple satellites and airborne missions. The new study takes a single type of measurement -- height as measured by an instrument that bounces laser pulses off the ice surface -- providing the most detailed and accurate picture of ice sheet change to date.
The researchers took tracks of ICESat measurements and overlaid the denser tracks of ICESat-2 measurements from 2019. Where the two data sets intersected -- tens of millions of sites -- they ran the data through computer programs that accounted for the snow density and other factors, and then calculated the mass of ice lost or gained.
"The new analysis reveals the ice sheets' response to changes in climate with unprecedented detail, revealing clues as to why and how the ice sheets are reacting the way they are," said co-author Alex Gardner, a glaciologist at NASA's Jet Propulsion Laboratory in Pasadena, California.
The study found that Greenland's ice sheet lost an average of 200 gigatons of ice per year, and Antarctica's ice sheet lost an average of 118 gigatons of ice per year. One gigaton of ice is enough to fill 400,000 Olympic-sized swimming pools.
Of the sea level rise that resulted from ice sheet meltwater and iceberg calving, about two-thirds of it came Greenland, the other third from Antarctica, Smith said.
"It was amazing to see how good the ICESat-2 data looked, right out of the gate," said co-author Tom Neumann at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "These first results looking at land ice confirm the consensus from other research groups, but they also let us look at the details of change in individual glaciers and ice shelves at the same time."
In Greenland, there was a significant amount of thinning of coastal glaciers, Smith said. The Kangerlussuaq and Jakobshavn glaciers, for example, have lost 14 to 20 feet (4 to 6 meters) of elevation per year. Warmer summer temperatures have melted ice from the surface of the glaciers and ice sheets, and in some places warmer ocean water erodes away the ice at their fronts.
In Antarctica, the dense tracks of ICESat-2 measurements showed that the ice sheet is getting thicker in parts of the continent's interior, likely as a result of increased snowfall, Smith said. But the loss of ice from the continent's margins, especially in West Antarctica and the Antarctic Peninsula, far outweighs any gains in the interior. In those places, the ocean is also likely to blame.
"In West Antarctica, we're seeing a lot of glaciers thinning very rapidly," Smith said. "There are ice shelves at the downstream end of those glaciers, floating on water. And those ice shelves are thinning, letting more ice flow out into the ocean as the warmer water erodes the ice."
These ice shelves, which rise and fall with the tides,can be difficult to measure, said co-author Helen Amanda Fricker, a glaciologist at Scripps Institution of Oceanography at the University of California, San Diego. Some of them have rough surfaces, with crevasses and ridges, but the precision and high resolution of ICESat-2 allows researchers to measure overall changes, without worrying about these features skewing the results.
This is one of the first times that researchers have measured loss of the floating ice shelves around Antarctica simultaneously with loss of the continent's ice sheet.
Ice that melts from ice shelves doesn't raise sea levels, since it's already floating -- just like an ice cube melting in a full cup of water doesn't overflow the glass. But the ice shelves do provide stability for the glaciers and ice sheets behind them.
"It's like an architectural buttress that holds up a cathedral," Fricker said. "The ice shelves hold the ice sheet up. If you take away the ice shelves, or even if you thin them, you're reducing that buttressing force, so the grounded ice can flow faster."
The researchers found ice shelves in West Antarctica, where many of the continent's fastest-moving glaciers are located, are losing mass. Patterns of thinning show that Thwaites and Crosson ice shelves have thinned the most, an average of about 5 meters (16 feet) and 3 meters (10 feet) of ice per year, respectively.
