NEW: Interactive Global Quake Map. Real Cool!

“We have recently experienced a period that has had one of the highest rates of great earthquakes ever recorded.”

Earthquake data consists of 10,835 seimic events from 1900 to July 2015 with magnitudes of six or greater on the Richter scale.

Earthquake Devastates Nepal

FEMAC has been monitoring the mapping of the Nepal earthquake as well as helping with emergency communication methods used after the event.
The phones were down as well as the power for many days. Cell phone towers were not nearly effected but had full data and with limited calling ability. While the US media was reporting the numbers to be around 2,500 people died and nearly 7,000 were injured by the quake, we learned from local Nepal media outlets that the poles did not include deaths outside of the city. It took a week for US to catch up on this. Also the media in Nepal was scaring everyone about another quake will hit soon. In reality, USGS uses the studies of events and this was no different. Matter of fact, the USGS even predicted the earthquake to be just a few years earlier and is not expected to return for another 85 years. While saving lifes is a priority, the unknown can also cause panic.
It was very nice to see how the local Kathmandu Living Labs and Openstreetmap was able to work globally to connect mappings to many resources including many Red Cross services.
What would would this be like if FEMAC was also in place and communications were greatly enhanced.

Some Coastal Communities May Not Have Time for Tsunami Evacuation

Released: 4/13/2015 3:05:00 PM
PORTLAND, Ore. — Tens of thousands of people along the U.S. Pacific Northwest coastline may not have enough time to evacuate low-lying areas before tsunami waves arrive, according to a new publication by researchers at the U.S. Geological Survey, University of Colorado Boulder, and California State University, Sacramento.

“All coastal communities in the U.S. Pacific Northwest are vulnerable to varying degrees to tsunami hazards from a Cascadia subduction zone earthquake,” said Dr. Nathan Wood, lead author of the study and scientist with the USGS. “Having a better sense of how a community is specifically vulnerable provides officials with the ability to develop outreach, preparedness, and evacuation plans that are tailored to local conditions and needs.”

The authors detail their findings in the scientific journal “Proceedings of the National Academy of Sciences.” They examined the 49 cities, seven tribal reservations, and 17 counties from northern California through northern Washington that are directly threatened by tsunami waves that could be generated by a future Cascadia subduction zone earthquake. The scientists evaluated the number of people or businesses exposed to tsunami hazards, as well as demographics and evacuation time by foot for each of these communities.

The Pedestrian Evacuation Analyst—Geographic Information Systems Software for Modeling Hazard Evacuation Potential

September 17, 2014:
Recent disasters such as the 2011 Tohoku, Japan, earthquake and tsunami; the 2013 Colorado floods; and the 2014 Oso, Washington, mudslide have raised awareness of catastrophic, sudden-onset hazards that arrive within minutes of the events that trigger them, such as local earthquakes or landslides. Due to the limited amount of time between generation and arrival of sudden-onset hazards, evacuations are typically self-initiated, on foot, and across the landscape (Wood and Schmidtlein, 2012). Although evacuation to naturally occurring high ground may be feasible in some vulnerable communities, evacuation modeling has demonstrated that other communities may require vertical-evacuation structures within a hazard zone, such as berms or buildings, if at-risk individuals are to survive some types of sudden-onset hazards (Wood and Schmidtlein, 2013).

Researchers use both static least-cost-distance (LCD) and dynamic agent-based models to assess the pedestrian evacuation potential of vulnerable communities. Although both types of models help to understand the evacuation landscape, LCD models provide a more general overview that is independent of population distributions, which may be difficult to quantify given the dynamic spatial and temporal nature of populations (Wood and Schmidtlein, 2012). Recent LCD efforts related to local tsunami threats have focused on an anisotropic (directionally dependent) path distance modeling approach that incorporates travel directionality, multiple travel speed assumptions, and cost surfaces that reflect variations in slope and land cover (Wood and Schmidtlein, 2012, 2013).

The Pedestrian Evacuation Analyst software implements this anisotropic path-distance approach for pedestrian evacuation from sudden-onset hazards, with a particular focus at this time on local tsunami threats.Read More…

Just before 11 a.m. on March 22, 2014, an ominous rumble startled the residents of the community of Oso, Washington, about an hour’s drive from Seattle. It was the terrifying sound of what would become the United States’ deadliest landslide in decades. The equivalent of one million dump truck loads of earth came plummeting down the valley. In a little over two minutes, a pile of debris up to 75 feet deep slammed into the neighborhood of close to 50 homes. While a massive search and rescue effort continues at the site, geologists are tracing the geological history of Oso to explain why the site was so unstable. But all around the world, scientists have reason to fear that the worst is yet to come. Globally, landslides and other ground failures take a tremendous human and economic toll, and with climate change bringing a sharp rise in intense precipitation events in many countries, the threat of bigger, more frequent landslides, like one that buried at least 350 people in Afghanistan this spring, is growing. In the Himalayas, the threat of devastating landslides is always lurking. As NOVA surveys landslide danger zones, discover how and why landslides happen, and how radar monitoring technologies could help predict landslides and issue life-saving warnings.
