Redoubt volcano activity

Redoubt volcano errupting

Alaska's Redoubt volcano, near Anchorage, Alaska, began erupting March 22, 2009 and has done so six times in the past two days. Mount Redoubt has erupted three other times in the 20th century: 1902, 1966, and 1989. 

There are many sources of information available about Mt. Redoubt's most recent eruptions. The USGS Newsroom has updates about recent activity. The Alaska Volcano Observatory has frequently updated information and images of Redoubt and other volcanoes in the area. Additionally, NASA's Earth Observatory is releasing imagery from its Moderate Resolution Imaging Spectroradiometer (MODIS) which is mounted on the Terra satellite.

Integrated Ocean Drilling Program core locations in Google Earth

Detail view of IODP hole locations on Google Earth

The Integrated Ocean Drilling Program (IODP) has made the location and scientific information about each of its core locations available in Google Earth. The KML file displays the precise location (latitude and longitude) of each core and gives scientific information including data about the hole, core sample, and links to related data. Additionally, users can download a broad range of data for each core location.

The data comes from "the Core Data from the Deep Sea Drilling Project Legs 1-96 CD-ROM produced in 2000 by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration, National Environmental Satellite, Data, and Information Service, National Geophysical Data Center, and collocated World Data Center for Marine Geology and Geophysics, Boulder. Data were compiled in cooperation with the U.S. Science Support Program, the Joint Oceanographic Institutions, Inc., and the U.S. National Science Foundation."

The Google Earth layer also includes data from holes drilled as part of the Ocean Drilling Program (ODP) and the Deep Sea Drilling Project (DSDP).

Library patrons can access both Google Earth and Google Earth Pro at the Earth Sciences and Map Library.
