The terrible tragedy in Nicaragua and Honduras from Hurricane Mitch's extraordinary rainfall was made worse by a volcano. The volcano didn't erupt, and it isn't even listed separately among the 1,511 volcanoes known to have been active in the past 10,000 years.

A 1,262-m-deep (4,139-ft-deep) research hole was drilled in the southwest corner of Kīlauea's caldera in 1973. At the time, this was the deepest hole in the summit region of any active volcano on earth.

Kīlauea Volcano's summit has been slowly subsiding since 1983, the year that the ongoing Pu`u O`o-Kupaianaha eruption started. This broad and gentle cone-shaped downwarping of the summit is centered about 1,500 m (one mile) south of Halema`uma`u Crater, where the ground's surface is now 1.3 m (4.3 ft) lower than it was in 1983.

Rapid landscape changes take place during Kīlauea's east rift zone eruption. Visitors to the coastal plain six months ago could have watched lava spilling from tubes at two major ocean entries south of Royal Gardens. By July 11, the eastern entry, at Waha`ula, had ceased.

The Chain of Craters marks the location of Kīlauea's upper east rift zone. The chain reaches southeastward from the summit caldera and then gradually bends into the overall east-northeast trend of the rift zone.

You hear a low rumbling sound; the walls of your house shake a little; objects on the shelves skip around, maybe even fall off the shelf. Was that an earthquake?

Groups of students of all ages frequently visit the U.S. Geological Survey's Hawaiian Volcano Observatory while they are on an excursion to Hawaii Volcanoes National Park. When prior arrangements are made, we escort them around our facilities and give a short talk on our mission and program.
