Chance of damaging earthquake shaking in the next 100 years, with areas colored red the most
 likely. Population exposure estimates are rounded to the nearest 1000.  USGS image

THE CHANCE IS MORE THAN 90% THAT HAWAI'I ISLAND IS LIKELY TO EXPERIENCE DAMAGING GROUND SHAKING from an earthquake in the next century, according to a new model from U.S. Geological Survey, released just before Christmas. The chance is more than 90 percent for this island, Maui, Kaho'olawe and part of Lana'i, and 75 percent to 90 percent for half of Lana'i and all of Moloka'i, The risk drops off to 25 percent to 75 percent for O'ahu and under 25 percent for Kaua'i.
    The creators of the new model note that "Hawai’i is a seismically active state, as indicated by the thousands of earthquakes recorded each year by the USGS Hawaiian Volcano Observatory. Damaging ground shaking has occurred over the decades, with two M6.7+ earthquakes in 2006 and 2018 and most recently a M5.2 earthquake on July 5, 2021 that was felt by more than 1300 people and a M6.2 earthquake on October 10, 2021 that was felt by more than 3500 people.
     "Earthquakes are often associated with volcanic activity and, therefore, monitoring current volcanic activity (e.g., Kilauea volcano has been erupting since September 29, 2021) is important as it could lead to large earthquakes," says the report.
    The updated ground shaking model, published on-line in the journal Earthquake Spectra, shows a 90% chance that the 345,000 people on the islands of Hawai’i and Maui could experience damaging levels of shaking during the next 100 years. A lower but significant chance of damaging shaking is expected across O'ahu; within the southeastern portion of the island near Honolulu there is a greater than 50% chance of damaging shaking occurring during this period. Levels of shaking on the southernmost islands are comparable to shaking levels expected across portions of coastal California.
Earthquake sources on the Island of Hawaii include (1) locations of shallow Quaternary faults (solid lines, colors represent age
 of faulting), (2) locations of places where deep faults (décollements) are known (dashed lines), and (3) locations of volcanoes (triangles). Large M>6 earthquakes with dates and magnitudes shown in table below figure. USGS image
    “The previous hazard model was developed over 20 years ago and since that time we have experienced several large earthquakes, volcanic eruptions, and have collected deformation, soil, and strong motion data that can be used to improve this forecast,” said Mark Petersen, USGS research geophysicist and lead author of the publication. “We collaborated with scientists and engineers across Hawaii and the rest of the U.S. to build these models. The new seismic hazard maps can be used to update building codes and other planning documents which should improve seismic safety across Hawai’i.”
The map and publication feature new earthquake catalogs, assessments of activity on active faults using geologic and geodetic (GPS) measurements, and evaluations of strong shaking data to define the ground shaking levels expected from earthquakes on the Hawaiian Islands.
    Ground shaking is forecasted to be highest near the active volcanos of Kīlauea and Mauna Loa in the southernmost portion of the Island of Hawai‘i (Figure 2). Here magmatic activity pushes the crust outward toward the ocean along a nearly horizontal fault located about 6 miles (10 kilometers) beneath the surface. Large earthquakes occurred on this zone in 1868, 1975, 2018 and 2021. The 2018 earthquake was followed by a volcanic sequence that included numerous seismogenic collapses of Kīlauea volcano’s summit crater floor. These provided data that helped define the shaking levels predicted by the model.
     “Repeated collapses of the volcanic caldera may have also caused damaging ground shaking during the 2018 volcanic eruption, so a new model was developed to evaluate this “Repeated collapses of the volcanic caldera may have also caused damaging ground shaking during the 2018 volcanic eruption, so a new model was developed to evaluate this risk,” said Petersen.
Seismicity of Hawaii: earthquakes M>5 from the 1840-1899, 1900-1959,
 1960-2019 catalogs shown separately. While earthquake activity remains
 high today, it seems to have decreased over the past 60 years, which
 could be related to less volcanic activity at Mauna Loa. USGS image
    While earthquake activity remains high today, it seems to have decreased compared to the preceding century which could be related to less volcanic activity at Mauna Loa (Figure 3). Variations in earthquake activity are considered in the new models with the expectation that earthquake activity could revert back to previous levels or continue at the current level.
    Forecasted shaking levels on the islands to the northwest of Maui are lower, and damaging earthquakes are less common since this region is farther from the magma source that currently lies beneath the Island of Hawai‘i. Earthquakes in this region result from bending of the earth’s crust due to the weight of overlying volcanos and from nearby oceanic fracture zones.
    “The Hawai’i Earthquake and Tsunami Advisory Committee thanks the USGS and University of Hawaii at Mānoa for their close collaboration in updating the seismological science since the previous hazard model was considered,” said Rhett Butler.
    Despite less frequent earthquake activity and a lower chance of damaging shaking, earthquakes on the northern part of the Island of Hawai'i and on Maui, the islands of Lānaʻi, Moloka'i, O'ahu, Kaua'i and Ni'ihau are still possible and can occur at depths that range from near the surface down to 25 miles (40 kilometers). A deep earthquake in 2006 occurred at a depth of about 18 miles (29 kilometers) and was strongly felt on the northern portion of the Island of Hawai'i and on Maui, causing extensive damage and losses. Other deep earthquakes occurred in 1938 near Maui, 1929 near Hualālai, and 1973 near Homomū. A large earthquake in 1871 near Lāna‘i is thought to have ruptured an oceanic fracture zone, and a 1948 earthquake near O‘ahu caused minor damage in Honolulu. These earthquakes signal the lower but significant risk to the northwestern portion of the Hawaiian island chain.

THE HIGHEST DAILY COVID CASE COUNT IN HAWAI'I COUNTY TO DATE is expected on Thursday. Early estimates from the State Department of Health indicate the potential for more than 220 cases to be reported. The highest case count to date was 206 cases, which was attributed to the onset of the Delta variant. Although counts continue to rise, hospitalizations are stable islandwide. Currently, nine COVID patients are hospitalized, with four in ICU and one on a ventilator.
    Those numbers are down considerably from the peak of the Delta surge, which had a high of 16 patients in the ICU, 12 on ventilators, and 69 COVID patients hospitalized in a single day.
    The island's population is currently 66% fully vaccinated, with 71% initiated. “We are seeing the positive effects of the vaccines in full effect,” said Mayor Mitch Roth. “Although the rise in numbers is certainly nothing to discount, we are comforted by the community’s response thus far and are confident that folks will continue to do the right thing to keep each other safe. Our administration remains ready to pivot if necessary but has no plans of placing any further restrictions on our residents at this time. Throughout the pandemic, we have worked hard to maintain a balanced approach that considers the working class, the kupuna, and the keiki to find equitable solutions for all.
   "We understand that some folks would like to see fewer restrictions, and others would like to see more, but at this time, we believe that we have figured out what works, and we are committed to sticking to that. We know that we won’t make everyone happy. Still, we will continue to operate with the best interest of the County and its residents in mind as we navigate forward using science, data, and aloha as justification of our actions and policies.”
    The statement says, "the County would like to applaud further the preventative measures the community has taken on their own accord to protect themselves and their loved ones throughout the pandemic."
    Testing and vaccination sites remain readily available islandwide and can be found at hawaiicounty.gov/coronavirus. Boosters remain the best defense against serious illness, and residents are encouraged to get theirs today if they haven’t already.

THE NEW LIMIT FOR INDOOR GATHERINGS AS A RESULT OF THE COVID SURGE IS TEN. Hawaiʻi County has reduced the indoor gathering limit as COVID-19 cases continue to surge statewide.
The limit is down from 25 persons allowed indoors, as was previously specified in Mayor's First Amended COVID-19 Emergency Rule No.19, originally signed on Nov. 30.
    Mayor's Second Amended COVID-19 Emergency Rule No.19, signed Dec. 27 by Managing Director Lee Lord, makes no other changes to the emergency rules. Lord signed for Mayor Mitch Roth due to Roth's mandatory quarantine related to the mayor testing positive for COVID-19.
    "We know people are going to gather to celebrate the New Year, and we want to ensure that if they do, that they do so outdoors, where it's safe," said Mayor Mitch Roth. "The new variant is extremely transmissible and is spreading quickly. The science says that outdoor gatherings are much safer than indoors, and we would like to encourage all of our residents to adhere to the new limits. We don't want to roll back any other restrictions, and the only way for us to ensure that we don't have to is by doing what's in the best interest of everyone in our community – mask up, distance when possible, and stay home if you feel sick."
    The County of Hawaiʻi would also like to remind residents of the importance of getting their booster shots to combat the surge of COVID-19 in our community. Boosters are free and are being administered islandwide.
    Visit hawaiicounty.gov/vaccination to find a distribution site.
