Scientists warned that Auckland is vulnerable to volcanic eruptions. During the last 250,000 years, Auckland's volcanoes have totally changed the Auckland landscape. The scientists used a variety of devices and models to explore in a new way the lava flows of
The thermal detectors on the MODIS instrument have identified areas on tops of Kamchatkan Shiveluch and Kizimen volcanoes that are warmer than background. Actively erupting volcanoes typically show such warm areas. Between the two more active volcanoes lie
