Open Source Tools Help Earthquake Researchers Stay a Step Ahead

As news that a series of powerful earthquakes were shaking the coast of Mexico in Baja, Calfornia, no doubt researchers all across the globe were keeping a watchful eye on the data as it rolled in. Many geological research facilities around the world use or are in the process of developing open source software and applications designed to interpret and share information with other researchers. Let's take a look at some examples. OpenSees is an open source software framework for developing apps that help understand what happens to structures during and after earthquakes to help engineers design stronger buildings. It's sponsored by the Pacific Earthquake Engineering Research Center and maintained by a team of developers from such notable educational institutions as University of California, Berkeley and Stanford University. Researchers are also using OpenSees to understand the potential ill-effects of seismic activity on California's viaducts and bridges.    Australia is no stranger to earthquakes so the government agency Geoscience Australia has developed the Earthquake Risk Model to determine ground motion and loss scenarios based on the seismic strength of a quake. It's an event-based tool that has helped the country develop disaster and emergency management response scenarios and, with further development, could connect with earthquake monitoring systems to help researchers produce loss assessments from previously recorded events.    The Global Earthquake Model (GEM) is a cooperative effort among several organizations worldwide to produce open source risk assessment software that will help calculate the hazards and risks of earthquakes and subsequent tsunamis around the world. It can be used to measure risks locally, regionally, or globally, and can be updated dynamically as incidents occur. The overall goal of the five-year project is to "produce software and tools that help to reduce earthquake deaths, destruction, dislocation, and monetary losses. GEM will provide a basis for comparing earthquake risks across regions and across borders, and thereby be the necessary first step towards increased awareness and actions that reduce earthquake risk."    When it comes to natural disasters, it's vital that data and research findings be shared among policy and decision makers as quickly as possible. MAEviz is a project headed up by the Mid-America Earthquake Center that helps reduce the time it takes to share information between researchers, engineers, and groups that need access to the most recent earthquake data available. Built with open source tools, MAEviz is easily extensible and users can quickly add new research methodologies, source data, and study findings as they are discovered. The information can then be manipulated to assess 48 different types of impact from seismic activity, from geographic to socio-economic. Results can be displayed as charts, graphs, tables, and even 3D models.    These are but a few of the dozens of earthquake-related open source projects being managed around the world by hundreds of universities and scientific organizations. It surely must be a comfort to anyone living in an earthquake-prone part of the country to know that so many minds are working together to find ways to keep people safe from the ravages of natural disasters.

by Bobby Vassallo on Jul. 28, 2010Whether an earthquake can be "predicted" remains to be seen. Certainly, the recent earthquakes in Mexicali, MX were expected. What I feel is the best use of these open-source seismic tools currently, is how quickly they can predict and confirm a Tsunami resulting from a sizable earthquake. This is becoming well-documented.
I was just in New Zealand discussing these topics with officials from 3 cities on the coast. They are very keen on the importance of early warnings to these oncoming killer tsunamis and are very worried about one coming soon. The recent Chilean earthquake only heightened their fears.

by James Larson on Jul. 30, 2010GEM is a welcome collaborative of specialists and societies which will greatly speed the process of understanding and the possibility of predicting these devastating quakes. Bobby Vassallo was correct in his assessment, I believe, that the likelihood of earthquakes is predictable, but timing is still not. He should know.
I checked out the site, It is a helpful site, full of information, history and preparedness. A chart on the home page shows how the intensity of earthquakes has risen in the past few years, alarmingly.
