Photogrammetric Engineering & Remote Sensing
is the official journal of the
American Society for Photogrammetry and Remote Sensing. It is devoted to the
exchange of ideas and information about the applications of photogrammetry,
remote sensing, and geographic information systems. The technical activities of
the Society are conducted through the following Technical Divisions: Geographic
Information Systems, Photogrammetric Applications, Lidar, Primary Data
Acquisition, Professional Practice, and Remote Sensing Applications. Additional
information on the functioning of the Technical Divisions and the Society can
be found in the Yearbook issue of
PE&RS.

Though Kilauea has been erupting continuously from the Pu’u O’o vent since 1983,
the eruption took a dangerous turn on May 3, 2018, when new fissures opened in the
residential neighborhood of Leilani Estates. Three weeks later, some fissures have
become less active but several others have emerged along the Lower East Rift Zone,
including a few just northeast of Leilani Estates.
As of May 25, 2018, geologists with the U.S. Geological Survey were tracking 23
fissures. One of the most active is fissure 22, which has shed enough lava to create a
channel that extends all the way to Hawaii’s southeastern coast. That lava is entering
the ocean near MacKenzie State Park. Though it is routine for lava from Kilauea to reach
the ocean, this is a new entry point.
The Operational Land Imager (OLI) on Landsat 8 acquired the data for this false-color
view of the lava flow as it appeared on the night of May 23, 2018. The image is based
on OLI’s observations of shortwave infrared and green light (bands 6-5-3). It was cloudy
when the data was acquired, but a small break in the clouds made it possible to image
the lava flows. The purple areas surrounding the flows are clouds lit from below. The
animation also makes use of a daytime-image from OLI, with information about the
location of roads and coastlines.
Geologists with the Hawaiian Volcano Observatory are monitoring the fissure eruptions
closely. While seismometers and other ground-based instruments can track the
underground movement of magma to some degree, it is not possible to predict with a
high degree of accuracy how long a particular fissure will remain active or how much
lava it will produce.
The U.S. Geological Survey and Hawaii County Civil Defense are the best sources of
information about the most recent activity at Kilauea.
