Hawaii Kīlauea Volcano Too Hot For Cruise Passengers – The Kilauea volcano (see live video stream below) has now been erupting since May 3rd, and part of the lava flowing into the ocean created an island 20 to 30 feet in diameter that appeared on July 12, according to the United States Geological Survey(USGS).
Kīlauea is a currently active shield volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the island of Hawaii. Located along the southern shore of the island, the volcano is between 300,000 and 600,000 years old and emerged above sea level about 100,000 years ago.
On Monday, July 16, 2018, there were 23 people on the Lava Ocean Tours injured when a “lava bomb” soaring from the Kilauea volcano crashed through the vessel’s metal roof. Lava Ocean Tours embarked from Wailoa Small Boat Harbor in Hilo.
Officers are now in the process of interviewing injured passengers at the Hilo Medical Center. In initial reporting passengers in the say the vessel was outside of the U.S. Coast Guard-established safety zone. Along with first responders both state and county officers were at the Wailoa ramp at the Wailoa River State Recreation Area in Hilo, when the boat returned after the incident. A 20-year old woman received major trauma to her leg and the others suffered burns and scrapes.
Truth in advertising – The Lava Ocean Tours
Lava Ocean Tours website promotion states, “Lava Ocean Tours Big Island lava boat tours are an exciting way to experience the molten hot lava entering the sea. See, Hear & Feel the heat from your front row seat onboard one of our world class catamarans.”
Lava Ocean Tours are a popular cruise ship excursion. Cruise ships calling in Hawaii are Celebrity Cruises’ Celebrity Solstice, Princess Cruises’ Grand Princess and Star Princess, Carnival Legend and Carnival Splendor, Holland America Line’s Amsterdam and Noordam, Royal Caribbean Cruise Lines’ Explorer of the Seas and Radiance of the Seas, Crystal Symphony, Oceania Cruises’ Insignia and Cunard Line’s Queen Elizabeth.
A little baby islet, only about 20 or 30 feet from edge to edge, popped up off the coast of the Big Island. But the islet didn’t last long. Only a few days later, a fresh pump of lava filled in a track between the coast and the baby isle, turning it into isthmus instead.
Honolulu Harbor has two cruise ship terminals. The primary cruise ship terminal is at Pier 2. The entrance to the terminal is at the West end of Channel St, off Ala Moana Boulevard.
The alternate cruise ship terminal is at Pier 11. The entrance is on the North extension of Aloha Tower Drive.
United States Geological Survey – July 20 2018 Warning
KILAUEA VOLCANO (VNUM #332010)
19°25’16” N 155°17’13” W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE
Kīlauea Volcano Lower East Rift Zone
Fissure 8 continues to erupt lava into the perched channel leading northeastward from the vent. During this morning’s overflight, the channel was incandescent its entire length from vent to ocean entry. The most vigorous ocean entry is located a few hundred meters northeast of the southern flow margin, though a few small pahoehoe toes were entering the ocean on either side of the channel’s main entry point. The southern margin of the flow is unchanged from yesterday, and about 500 m (0.3 mi) from the boat ramp at Isaac Hale Park.
No other fissures are active this morning.
Pele’s hair and other lightweight volcanic glass fragments from the lava fountain at Fissure 8 continue to fall downwind of the fissure, dusting the ground within a few hundred meters (yards) of the vent. High winds may waft lighter particles to greater distances. Residents are urged to minimize exposure to these volcanic particles, which can cause skin and eye irritation similar to volcanic ash.
HVO field crews are on site tracking activity as conditions allow and are reporting information to Hawaii County Civil Defense. Observations are also collected on a daily basis from cracks in the area of Highway 130; no changes in temperature, crack width, or gas emissions have been noted for several days.
Volcanic gas emissions remain very high. VOG information can be found at https://vog.ivhhn.org/
The ocean entry is a hazardous area. The interaction of lava with the ocean creates “laze”, a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that drifts downwind and can irritate the skin, eyes, and lungs. Close to the ocean entry, flying debris from explosive interaction between lava and water is a primary hazard. Additionally, submarine magma-water interaction can result in explosive activity beyond the visible lava delta, creating a hazard that extends offshore. The lava delta is unstable because it is built up to 800 m (0.5 mi) from the former coastline on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea.
Magma continues to be supplied to the Lower East Rift Zone. Seismicity remains relatively low although higher amplitude tremor is occasionally being recorded on seismic stations close to the ocean entry.
Additional ground cracking and outbreaks of lava in the area of the active fissures are possible at any time. Residents downslope of the region of fissures should remain informed and heed all Hawaii County Civil Defense messages and warnings.
Kīlauea Volcano Summit
The last collapse event occurred at 4:36 p.m. HST yesterday (July 19). Seismicity at the summit decreased immediately following the event and is now back to 20-40 earthquakes per hour. The next collapse event is expected to occur tonight or tomorrow morning. Inward slumping of the rim and walls of Halemaʻumaʻu continues in response to the ongoing subsidence at the summit.
Sulfur dioxide emissions from the volcano’s summit are very low. This gas and minor amounts of ash resuspended by wind are being transported downwind. Small bursts of ash and gas may coincide with the summit collapse events. The summit region is occasionally impacted by sulfur dioxide from the lower East Rift Zone eruption.
