Most active seismic zone in the nation here...
January 29, 1993

Nearly everyone on the island of Hawai`i should have felt an earthquake this past week. As the accompanying map shows, Hawai`i was rattled by 11 earthqukes large enough to be felt in less than four days. 

Episode 51 continuing...
January 22, 1993

The eruption from the episode 51 vents, located on the west flank of the Pu`u `O`o cone on the East Rift Zone of Kīlauea Volcano, continues with little change. Lava is being fed to the coastline near Kamoamoa through a well-established underground tube system with only a few skylights, through which the flowing lavacan be seen from the air.

January 15, 1993

On Thursday an explosion in the crater of Galeras Volcano in Colombia killed six volcanologists attending an international workshop attended by more than 90 scientists, and killed an additional three people not attending the workshop.

Kīlauea: a youngster among world's active volcanoes...
January 8, 1993

One of the main impediments to predicting the future behavior of Kīlauea and especially Mauna Loa Volcanoes is the short historical record of each volcano. 

January 1, 1993

The Pu`u `O`o-Kupaianaha eruption now ranks as the longest-lived historic eruption on the East Rift Zone and the most destructive in Kīlauea's recent history. 

Underwater East Rift exploration reveals a few surprises...
December 11, 1992

The East Rift Zone of Kīlauea Volcano is 130 kilometers long, but only 55 kilometers of the rift is above sea level. The lower 75 kilometers of the rift is submarine and extends east-northeast from Cape Kumukahi to a depth of roughly 5,400 meters (17,700 feet). 

December 4, 1992

For the past 10 years, most of the evident changes on Kīlauea Volcano have occurred down the east rift zone near and downslope from the Pu`u `O`o and Kupaianaha vents. Last Sunday, a sequence of rockfalls occurred within the summit caldera that modestly changed the size and shape of Halema`uma`u Crater. 

Lava explodes into the sea at Kamoamoa...
November 27, 1992

Lava erupted from the episode 51 vents has been entering the sea at Kamoamoa since November 8. On Tuesday, a new phenomenon was observed. 

Lava continues to flow near Kamoamoa...
November 20, 1992

The eruption from the episode 51 vents has continued without interruption since October 2. The flows crossed the Chain of Craters Road near Kamoamoa in Hawai`i Volcanoes National Park on November 7. Since that time, flows have covered all of the Kamoamoa ruins, campground, parking lot, and picnic area, and have formed perhaps 30 acres of new land.

Volcano watchers should beware...
November 6, 1992

The eruption from the episode 51 vents has continued without interruption since October 2. The flows have now advanced to within 300 feet of the Chain of Craters Road inside Hawai`i Volcanoes National Park. The flows advanced over the pali during the last week-and-a-half and came within a quarter of a mile of Chain of Craters Road by early this week. 

October 30, 1992

The 10-year long eruption of Kīlauea Volcano continues from the episode 51 vents located on the west flank of the Pu`u `O`o cone. The flows advanced slowly from October 3 until October 28, when they began to flow over the pali above Kamoamoa.

October 23, 1992

The Hawaiian Volcano Observatory studies mainly the current activity of Hawai`i's volcanoes, and our eruption forecasts are limited to the short-term future (hours, days, months, sometimes a few years).
