20 Years of Eruption at Kilauea and Waiting for Mauna Loa

by Don Swanson,Volcanologist, Hawaiian Volcano Observatory

 

  • Kilauea's Pu'u O'o-Kupaianaha eruption, which began on January 3, 1983, is already the volcano's longest rift eruption in at least 600 years

Lava bubble burst explosion on active lava delta, Kīlauea, Hawai‘i

Two bubble bursts explode simultaneously as a consequence seawater mixing with lava in a lava tube beneath surface of a lava delta. Because of the confined conditions in the lava tube, explosive pressures build up as water, heated by contact with molten lava, expands instantly to steam. The explosive energy of the steam is sufficient to blast a hole through the top of the

Cinder Cones on Mauna Kea

Cinder cones at the summit of Mauna Kea. Mauna Kea is a dormant shield volcano on the north end of Hawaii Island. Astronomical observatories in the foreground.

Cinder cones (otherwise known as scoria cones) are the most common type of volcano on Earth. They’re also one of the smallest. They can often be found growing on larger volcanoes, in which case they’re dubbed

Kalapana Gardens subdivision inundated by Pāhoehoe, Kīlauea

Individual pāhoehoe flow fronts were typically only 10-20 cm thick as they moved through Kalapana. However, the thin leading edges of the flows quickly crusted over and stagnated. As lava continued to push beneath the crust, the cooled surface was lifted up until eventually lava again broke out of the sides and front of the inflated flows. In this way, many of the

The magnitude 7.2 earthquake in Kobe, Japan has resulted in extensive damage and a shocking number of fatalities and injuries. Japan has not experienced such a damaging earthquake since 1923, when an estimated magnitude-8.3 earthquake killed about 143,000 people in the Tokyo area.

A few weeks ago, we told you about the more than 67,000 earthquakes we recorded during the past year. Most of those earthquakes were so small that they were not felt and caused no damage.
