Lahar Detection System Developments at Mount Rainier

The video describes USGS efforts to improve lahar (mudflow) monitoring at Mount Rainier, an ice-clad volcano in Washington State with potential for dangerous volcanic mudflows. The presentation was given to colleagues in the US and in Ecuador by Andy Lockhart. Andy is a geophysicist with the the USGS/USAID Volcano Disaster Assistance Program, and he has worked to reduce the risk from lahars at many volcanoes worldwide. Warning systems at Mount Rainier are being developed with knowledge gained in other countries, including Colombia, Ecuador, and Guatemala.
