such as volcanic eruptions or fires, pose serious hazards to sensitive
ecosystems, transportation and communication networks, and to populated
Orbiting Earth-observing satellites gather and relay valuable data on these hotspot hazards as they develop around the globe.
Timely dissemination of this data to scientists and to local civil defense officials is crucial in efforts to understand and to minimize losses from hazardous hotspot activity.
together various sources of near-real-time data acquired by different Earth-observing
satellites and processed by scientists at the Hawaii Institute of Geophysics
and Planetology, University of Hawaii.
|Current Hotspot Monitoring Sites|
8/10 Hotspot Images
|Selected western-hemisphere sites updated every 10 to 30 minutes. Data is collected by geostationary GOES 8 and GOES 10 satellites in 15 minute intervals.|
|Globalwide maps of thermally significant events captured daily by MODIS|
O'o Vent Monitoring
|1 Hour, 4 Hour, Daily and Weekly plots of thermal activity from selected locations in Pu'u O'O Crater|
AVHRR hot spot maps of Mount Etna Volcano
|AVHRR data for Mount Etna fitted to a topographic base map and digital elevation model. Data are updated daily.|
Earth-observing satellites are operated by various commercial, national, and international programs, and the data are distributed to the scientific community, including the University of Hawaii. Earth-observing satellites collect data over different areas of the globe on various time scales and in various ways. Therefore, we post hotspot data acquired by separate satellite projects to individual websites. The data are posted on the web an average of 10 to 30 minutes after being acquired by an Earth-observing satellite. This lag time is required for data transmission and processing and varies for each satellite project.
