[MOcam] Mokuʻāweoweo Caldera from South Rim

This image is from a research camera positioned on the south rim of Mokuʻāweoweo, Mauna Loa's summit caldera, in Hawaiʻi Volcanoes National Park. The camera looks north-northwest, focusing on the southern part of the caldera. The 1940 cone is just right of center; the 1949 cone is on the caldera rim at left. The high point of Mauna Loa's summit is in the background.

Kīlauea Caldera - East Wide Angle from HVO Observation Tower [KEcam]

The webcams are operational 24/7 and faithfully record the dark of night if there are no sources of incandescence or other lights. Thermal webcams record heat rather than light and get better views through volcanic gas. At times, clouds and rain obscure visibility. The cameras are subject to sporadic breakdown, and may not be repaired immediately. Some cameras are

An Endangered Honeycreeper, the `Akikiki (Kaua`i Creeper), in Hawaii

Many species of Hawaiian honeycreepers have persisted into the 20th century because high elevation rain forests on the islands of Kaua’i, Maui, and Hawai’i are cool enough to limit transmission of introduced avian malaria (Plasmodium relictum). Malaria transmission is tied closely to the effects of temperature on development of malarial parasites within their
