Park emergency managers urge motorists to slow down and use caution on Highway 11, particularly between mile markers 28 and 29, and Pi‘i Mauna Road, where most damage occurred. The park, which has jurisdiction of Highway 11 between mile markers 28 and 38.5, is not closing Highway 11 at this time.
In addition, motorists are reminded that stopping for non-emergency purposes along the side and shoulders of Highway 11 in the park is prohibited.
“We are leaving Highway 11 open at this time, but will close it if it becomes unsafe for motorists,” said Chief Ranger John Broward. “We suspect we’ll find additional damage throughout the park once we have time to assess damage,” he said.
The earthquake also created sizable cracks and floor shifting in the park’s Visitor Emergency Operations Center and caused a temporary loss of power, and ruptured several water lines.
Most of Hawai‘i Volcanoes National Park has been closed since Friday, May 11, due to ongoing seismic activity, summit deflation, and a possible steam explosion at the summit of Kīlauea Volcano.

According to USGS, yesterday’s series of summit events reflect the most energetic explosions yet observed and could reflect the onset of steam-driven explosive activity.
Today, the 8:30 a.m. 4.4 quake was followed by quakes in the 2.1 to 3.7 range. A 2:30 p.m. statement from Hawaiian Volcano Observatory said, "Strong earthquakes within the summit of Kīlauea Volcano continue in response to ongoing deflation and lava column drop. As of the afternoon of May 16, the floor of Kīlauea caldera has dropped approximately 3 feet (90 cm). This movement is stressing faults around the caldera of Kīlauea, causing them to move and resulting in strong earthquakes of up to magnitude 4.4 thus far. |

"As deflation continues, strong earthquakes in the area around Kīlauea Volcano's summit are expected to continue and may become more frequent. Areas further from these earthquakes may feel some ground motion as well, but much less severe.
"The shallow depths of these earthquakes make them more damaging in the immediate vicinity of the epicenter, and individuals need to take precautions to minimize damage from the shaking, including the removal of unstable items from walls and shelves. Steep slopes should be avoided as they may become destabilized during strong earthquake."

Said the governor, "I thank
Secretary Mattis for his quick approval. This joint military task force will
provide the necessary state and federal resources to Mayor Kim and his Civil
Defense team. Together, we are committed to supporting the residents of Hawaiʻi
Island in their time of need."

International Volcano Health Hazard
Network produces printable and downloadable pamphlets, available online at ivhhn.org, that advise on preparing for ashfall, the health complications of volcanic ash, what to do after ashfall, and information about volcanic gases and the associated health hazards. The organization recommends, “If there is ash in your water, let it settle and then use the clean water. If there is a lot of ash in the water supply, do not use your dishwasher or washing machine. Water contaminated by
ash will usually make drinking water unpalatable before it presents a health
risk. You may eat vegetables from the garden, but wash them [with clean water]
first.”

SO2 LEVELS, according to the only two monitoring stations in Kaʻū, outside of Hawaiʻi Volcanoes National Park, registered mostly good air today. At Pāhala. the SO2 registered as good between midnight and 6 a.m., moderate between 6 a.m. and 10 a.m., and unhealthy for sensitive persons between 10 a.m and 10:30 a.m. The SO2 level was good for the rest of the afternoon with the exception of 45 minutes of moderate air.
Ocean View's SO2 level registered good over the last two days; at 9:30 a.m. this morning it registered as moderate for 30 minutes followed by good air for the rest of the day. See Hawaiʻi Short Term SO2 Advisory.
BRIG. GENERAL KENNETH HARA received the authority from
Secretary of Defense James Mattis today to command both the National Guard and
active military forces to plan for and be ready for mass air evacuations
should roadways in Puna be lost to lava.
Gov. David Y. Ige made the request and
announced today the formation of a Dual-Status Command, Joint Task Force 50, in
response to the Kīlauea lava flow. Ige’s formal request
to appoint Hara was submitted on Tuesday. The formation of this JTF
establishes a clear chain of command to maintain operational unity between
state and federal efforts and increase efficiency.

Hara is the Deputy Adjutant General and
Commander of the Hawaiʻi Army National Guard. He will oversee a joint Hawaiʻi
National Guard and active duty military joint task force. Based on the current
threat the JTF may be required for Search and Rescue, Incident Awareness and
Assessment, Debris Clearance, Security, and Emergency Evacuation.
A 22 personnel JTF advance team was
deployed to the Keaukaha Military Reservation in Hilo ,
on Monday, May 14, and began planning for potential missions. Pre-staging the
advance team will enable faster response to requests for military support made
by Hawaiʻi County.
Hara,
as the Dual Status Commander, is a legally authorized military officer who
assumes simultaneous but mutually exclusive command authority over both
National Guard forces and Title 10 federal military forces. While state and
federal military forces maintain separate and distinct chains of command, the
Dual Status Commander leads all military forces and directs their response
efforts.

Commander authority, click here.
PREPARING FOR ASHFALL WITH A RAIN WATER CATCHMENT SYSTEM
involves disconnecting tanks prior to ash falling, says the International
Volcano Health Hazard Network. All drainpipes and downspouts from gutters -
attached to a rain water system or otherwise - should also be disconnected to
stop drains from clogging, while allowing ash and water to empty from gutters
onto the ground. Rain water collection systems (tanks included) that are
uncovered, partially covered, or covered by a porous material - such a synthetic
mesh - should be covered completely to avoid contamination by ash.

Volcanic Ashfall Impacts Working
Group, volcanoes.usgs.gov,
states that “contamination of water supplies has been reported for several
historic eruptions. The most common problems resulting from ashfall are
increased levels of suspended ash in water (turbidity), which can cause a range
of problems for water treatment, and higher-than-usual demand for water. The
organization also recommends “disconnecting the downpipe from the roof to the
tank prior to the ashfall.”
“Tank water contaminated by ash is
unlikely to be a health hazard as elements released from the ash (particularly
iron, manganese, and aluminum) can impart an unpleasant metallic taste to the
water making it unpalatable to drink, with this effect outweighing the release
of any toxic elements such as fluorine from the ash,” states the Working Group,
and adds “it may be necessary to empty, clean and refill the tank,” if the
water becomes contaminated by ash.

The native silversword and lobeliads of Hawai‘i are spectacular examples of adaptive radiation, in which single colonizing ancestors have given rise to a stunning diversity of species – some of which are the world’s most critically imperiled plants. Learn how park managers have partnered with public and private organizations to bring these species back from the brink of extinction as McDaniel discusses rare plant management in the park.
