Kīlauea Volcano — Halema`uma`u Parking Lot Gone

View of the southern edge of the growing Halema‘uma‘u crater (middle right) during yesterday's helicopter-assisted work at Kīlauea's summit. The once-popular parking lot (closed since 2008) that provided access to Halema‘uma‘u is no longer—the parking lot fell into the crater this past week as more and more of the Kīlauea Crater floor slides into Halema‘uma‘u. The Crater

Kīlauea Volcano — Temperature Readings

HVO geologist measures 260 degrees C (500 degrees F) along ground cracks near fissure 10 in Leilani Estates. Geologists routinely make temperature measurements to track changes throughout the fissure complex in the lower East Rift Zone.

With funding from USGS data rescue initiatives, HVO scanned seismograms from a number of significant earthquakes and seismic sequences. Since last summer, volunteer Marcy Frenz has enthusiastically and diligently assumed scanning duties at HVO, working through the 1974–1984 interval spanning Mauna Loa Volcano's two most recent eruptions.
