Volcano Watch — An earthquake is the most likely disaster here
I will end my series of these columns with some thoughts about preparedness for future disasters and some personal thank-yous.
Volcano Watch — Clague leaving volcano observatory
The "Volcano Watch" column first appeared on November 3, 1991. In the last four plus years, the staff and I have written 207 columns covering a wide range of topics, including updates on the ongoing eruption of Kīlauea, hazards posed by that eruption, long-term volcanic and seismic hazards in Hawaii, as well as descriptions of volcanic and seismic events worldwide.
Volcano Watch — Kīlauea lava status; shoreline hazard
The eruption on Kīlauea's East Rift Zone continued without any pauses this past week. The active flows are confined to the eastern side of the Kamoamoa flow field, and most of the lava is entering the ocean near Kamokuna.
Volcano Watch — O‘ahu, Ni‘ihau, and Kaua‘i
In the last few weeks, we have reviewed the eruptive stages of Hawaiian volcanoes and have given brief overviews of the geologic history of Hawai'i Island and of Maui, Moloka'i, Lana'i, and Kaho'olawe, the islands that make up the Maui Complex.
Volcano Watch — Maui Nui, the Bigger Island
Last week, we presented a brief history of the island of Hawaii, the largest island in the Hawaiian chain. However, before the island of Hawaii formed, Maui Nui was an even larger island.
Volcano Watch — Volcanoes of the Big Island
The Island of Hawai'i consists of five coalesced volcanoes, a submarine volcano that has already subsided below sea level, and another, Lō‘ihi Seamount, that has yet to grow to sea level.
Volcano Watch — Evolution of Hawaiian volcanoes
The 15 volcanoes that comprise the eight principal Hawaiian Islands are the youngest in a linear chain of about 125 volcanoes that stretches for about 3,600 miles across the north Pacific.
Volcano Watch — Kīlauea eruption status, September 1, 1995
The long-lived eruption on Kīlauea's East Rift Zone took a short break starting Tuesday, August 22. Before the pause in activity, we observed that the lava pond inside Pu'u 'O'o Crater was unusually deep (more than 310 feet below the rim).
Volcano Watch — Littoral cones
A recent visitor to the Hawaiian Volcano Observatory was involved with the removal of abandoned vehicles from the area surrounding the Sand Hill cone in coastal Puna. He was puzzled by the location of an apparent volcanic vent so far away from the rift zone of Kīlauea.
Volcano Watch — Evolution and island hopping
The rapidly changing geology in the Hawaiian Islands has profound consequences for the plants and animals in Hawai'i on several time scales.
Volcano Watch — Kīlauea eruption status, August 11, 1995
The eruption on Kīlauea's East Rift Zone continues with little change. Lava is erupting from two vents located on the south and west flanks of the Pu'u 'O'o cone.
Volcano Watch — Soufriere Hills, Montserrat
Soufriere Hills Volcano on the island of Montserrat in the Caribbean became active on July 18, 1995. This is the first eruption of the volcano in historic time.
