Maui now hawai‘i volcano eruption update fuming, rumbling precedes large quake electricity usage calculator kwh

#####

The Kīlauea eruption continues on Hawaiʻi Island with several new fissures reported over the last 24 hours. The new lava outbreaks resulted in “ copious amounts” of sulfur dioxide gas steaming from cracks and fountains of lava rising 100 feet in the air at some locations.

Fissure 2 commenced in the early morning hours on Friday on Kīlauea Volcano’s lower East Rift Zone on Makamae and Leilani Streets. The outbreak began as a small area of spattering in a residential driveway and became more vigorous, with lava thrown over neighborhood power lines.

By 6 a.m., steaming cracks preceded a new fissure on Kaupili Street. The US Geological Survey reported “fuming” and “rumbling” sounds that increased with “large bubble bursts” reported at the location. This fissure spread lava on the road measured at approximately 2 yards thick.

These events preceded a large 6.9 earthquake on the south Flank of the Kīlauea volcano that sent a column of red ash into the air, and resulted in severe shaking near the epicenter. Scientists with the Hawaiian Volcano Observatory say the quake was the strongest quake in Hawaiʻi in more than 40 years, since 1975. It was centered about 10 miles SW of Leilani Estates and was felt as far away as the Island of Kauaʻi. The mainshock was preceded by a strong magnitude-5.4 earthquake approximately one hour prior.

The Maui Emergency Managment Agency advises that, locally generated tsunami’s will have a very short travel time and staff may not be able to sound sirens or send messages prior to impact. If you feel an earthquake strong enough that you have difficulty standing, the agency advises that you move away from the coastlines and get to higher ground. An interactive map of tsunami inundation zones is available at tsunami.coast.noaa.gov.

Officials with the Hawai ʻi Emergency Management Agency say the recent activity in the area of Leilani Estates has resulted in dangerously high concentrations of sulfur dioxide, a gas that is a strong respiratory system Irritant and can cause serious eye, nose, and skin irritations, coughing, shortness of breath, or other effects. The agency released the following information relating to sulfur dioxide and vog:

Vog (a local term for volcanic emissions from eruptions) is a hazy mixture of SO 2 gas and aerosols, which are primarily composed of sulfuric acid droplets and other sulfate (SO 4) compounds. Aerosols are created when SO 2 and other volcanic gases combine in the atmosphere and interact chemically with oxygen, moisture, dust, and sunlight over periods of minutes to days.

SO 2 presents particularly serious threats to the health of individuals with asthma or other respiratory conditions, people with cardiovascular disease, seniors, infants and children, and new and expectant mothers, but healthy people may experience symptoms as well. It is of particular concern in the current situation because the fissures are in inhabited areas; more SO 2 is found in volcanic gasses closer to their source.

The Interagency Vog Dashboard offers more information on sulfur dioxide and other volcanic emission concerns, and serves as one location where you can access a wide range of available information regarding volcanic emissions (vog). It is available at: http://ivhhn.org/vog/
