The emission of volcanic gases, including sulfur dioxide and hydrogen sulfide, is not unusual at the summit of Kīlauea. However, sulfur dioxide gas emission rates are now lower than they have been since before 1983, with about 50 tonnes/day measured at the summit of the volcano on the day of this photo (October 24).

These two plots show summit tilt (ground deformation) and seismicity (earthquake counts) on Kīlauea Volcano between July 15 and August 5, 2018. A regular pattern emerged in which seismicity gradually increased over 1-3 days (bottom), until the caldera floor suddenly dropped several meters (yards) in a matter of seconds.

This aerial view of the western part of Kīlauea Volcano's caldera was taken on August 6, 2018. The down-dropped block is faulted about 120 m (400 feet) below the caldera floor. Many 19th-century lava flows are exposed in the fault scarps. Halema‘uma‘u (not visible) is to the left of this photo.

The inferred rupture area (white dashed line) of the May 4, 2018, magnitude-6.9 earthquake, with its foreshocks and first 10 days of aftershocks, spans an area of about 800 sq km (300 sq mi). Circle size indicates earthquake magnitude; color indicates earthquake depth. Magnitudes for some of the larger events are labeled.

GPS station P361, on Sawtell Peak, on a nice clear day. Electrical storms destroyed multiple antennas, including the GPS antenna--here under a protective plastic dome--and three communications antennas on the tower. Data from P361, along with data from other stations in the Yellowstone region, are sent to UNAVCO for free and open distribution.

Are you ready for an eruption? Mount Baker dominates the skyline of northwestern Washington and southwestern British Columbia. Glacier Peak is mostly hidden from view. Both volcanoes have erupted in recent centuries and will erupt again, disrupting the landscape and the lives of people downstream and downwind. Learn what to do and where to get information.

Mount Rainier is much more than a mountain in the sky. Constructed of hundreds of lava flows, and capped by as much glacier ice as all other Cascade volcanoes combined, Rainier's steep rubbly slopes and abundant water make it prone to landslides and lahars, especially during eruptions. Are you ready for an eruption?

Left: Horseshoe-shaped crater of Mount St. Helens in 1980, formed by a landslide that removed the top of the volcano. The crater is about 2 km (1.2 mi) wide and the floor is about 600 m (1,970 ft) below the crater rim. Right: Halema'uma'u nestled in the summit crater of Kīlauea Volcano on August 1, the day before the last collapse event.

This comparison shows satellite images of Leilani Estates subdivision before and after the May-August 2018 eruption. The image on the right, collected in early September 2018, shows that the eastern portion of the subdivision has been covered by lava. The Fissure 8 lava channel runs northeast, with the Fissure 8 cone at the start of the channel.
