Kīlauea's ongoing east rift zone eruption continues, and lava enthusiasts are being treated with renewed opportunity to view the flows, subject to the advisories expressed by the National Park Service and the U. S. Geological Survey.

History is sometimes altered by events so insignificant that they pass without notice when they occur. Let's follow the chain of events that placed an American air base in the Philippines, in the shadow of Mount Pinatubo—a volcano whose eruptions devastated the base in 1991.

Many readers have visited the overlook in front of the Jaggar Museum, next door to HVO, and those of you who haven't should do so some time. A grand vista of Kīlauea's caldera awaits you, and many other sightseers as well. The hustle-bustle is commonly a little distracting.

Lava flowing from Kīlauea's ongoing eruption finally made its way to the ocean once again a couple of weeks ago. And for the first time in nearly a year, everyone—;from curious park visitors and staff, to intent photographers, to nerdy (and intent) volcanologists—have been treated to the enrapturing experience of seeing liquid rock encounter liquid ocean.

In the next 10 days, HVO loses two of its most dynamic research scientists. Peter Cervelli transfers to the Alaska Volcano Observatory in Anchorage, and David Sherrod moves to the Cascades Volcano Observatory in Vancouver, Washington.

Hawaiians had several stories about how their islands were formed. One version has Papa and Wakea mating and giving birth to the islands. The Big Island was first and Kaho'olawe was last. The more well-known story involves the goddess Pele and her travels to find a new home.

Every day at the Hawaiian Volcano Observatory, we scan incoming data from field instruments that will warn of new volcanic activity on the island. Kīlauea, of course, is already erupting. Mauna Loa and Hualalai have both erupted in the not-too-distant past, and each will erupt again in the future.

America’s rivers and streams are generally suitable for irrigation, supplying drinking water, and home and recreational uses. However, in areas with significant agricultural and urban development, the quality of our nation’s water resources has been degraded by contaminants such as pesticides, nutrients, and gasoline-related compounds.

Colossal natural disasters have been fodder for Hollywood movies long enough that we can recognize the basic recipe. A pinch of fact, a fistful of myth and exaggeration, and a large dose of spectacular special effects add up to an entertaining, but often preposterous disaster movie.

Much of the work done by the HVO staff depends on field activities. Either scientists and technicians visit field sites to make observations and measurements, or they establish monitoring instruments that send data back to the observatory by radio or other means.
