The 2018 eruption of Kīlauea was triggered by a decade-long build-up of pressure in the upper parts of the volcano.

Although the TEB flow was much less destructive than the 2018 LERZ eruption, it nevertheless threatened homes in lower Puna for months.

In cartography and geographic analyses related to volcanoes, especially in Hawai‘i, there is perhaps nothing more important than having an accurate digital model of topography.

Some regions monitored by the volcano observatories had geologically ‘young’ eruptions that are nonetheless old enough to lack written documentation, eyewitnesses, or first-hand accounts.

The water surface is a mosaic in constant motion, a scene that changes by the minute and hour. 

Between seismic swarms leading to sleepless nights, and sulfur smells leading to wrinkled noses, it has been a somewhat interesting week for Hawai‘i Island residents.

One of the fundamental premises of geology is that the "key to understanding the future is to understand the past."

The Koa‘e fault system connects Kīlauea’s East and Southwest Rift Zones south of the caldera.

Major earthquakes cannot be predicted.

By 1930, Hawai‘i had earthquake report cards that were distributed to the community by HVO staff for people to write detailed information about what they observed during earthquakes.
