INTRODUCTORY NOTE

The Hawaiian Volcano Observatory Summaries have been published in the current format since 1956. The Quarterly 

Summaries (1956 through 1973) and the Annual Summaries (1974 through 1985) were originally published as Administrative Reports. These reports have been compiled and published as U.S. Geological Survey Open-File Reports. 

The quarterly reports have been combined and published as one annual summary. All the summaries from 1956 to 

the present are now available as .pdf files at http://www.usgs.gov/pubprod.

The earthquake summary data are presented as a listing of origin time, depth, magnitude, and other location parameters. Network instrumentation, field station sites, and location algorithms are described. Tilt and other deformation 

data are included until Summary 77, January to December 1977. From 1978, the seismic and deformation data are 

published separately, due to differing schedules of data reduction. 

There are eight quarters—from the fourth quarter of 1959 to the third quarter of 1961—that were never published. 

Two of these (4th quarter 1959, 1st quarter 1960) have now been published, using handwritten notes of Jerry Eaton 

(HVO seismologist at the time) and his colleagues. The seismic records for the remaining six summaries went back to 

California in 1961 with Jerry Eaton. Other responsibilities intervened, and the seismic summaries were never prepared.

Chronology

The following Kïlauea eruption chronology covers the two recent reports and the six missing quarters:

Location Beginning Date Ending Date Comment

Kïlauea Iki crater (Kïlauea’s summit) 11/14/1959 12/20/1959 19 eruptive episodes

Kapoho (lower east rift zone) 1/13/1960 2/18/1960 4 eruption stages

Halemaumau (Kïlauea’s summit) 2/24/1961 2/24/1961 Intermittent activity during 

uninterrupted inflation following the 1960 eruption

Halemaumau (Kïlauea’s summit) 3/22/1961 3/25/1961 Same as above.

Halemaumau (Kïlauea’s summit) 7/10/1961 7/17/1961 Same as above.

Heiheiahulu (middle east rift zone) 9/22/1961 9/25/1961 First historical east rift eruption at this location

The 1959-1960 eruptions were among two of the most spectacular Kïlauea eruptions. The HVO staff was kept busy 

with acquisition of unusually high quantities of instrumental data and observations of the two sequences, which 

were separated by less than one month. Even with a year’s interval before the beginning of the summit-east rift sequence in 1961, the staff never caught up, and the seismic records were set aside for later study. 

A total of 1,672 earthquakes—1,106 for 1960 and 566 for 1961—are part of HVO’s cataloged database. The annual 

listings have been appended to the 1st Quarter Report of 1960 and to the 4th Quarter Report for 1961. The number of 

earthquakes is probably low, biased toward the larger magnitudes. The entire HVO catalog, including 1960 and 1961, 

is accessible from the ANSS CATALOG SEARCH site at http://www.ncedc.org/anss/catalog-search.

Summary of activities

In this quarterly report, the map showi~ the tilting on Kilauea

Volcano 'will include a contour map showing the total amount of altitude

change at the summit. This map is based on measurements at a system

of bench marks beginning near Bird Park and continues from there along

the Crater Rim road to the Crater Rim - Chain of Craters road junction

and'then to BM 35YY at Makaopuhi Crater. Also included in this system

of bench marks are spur loops, one into the center of the caldera east

of Halemaumau and one southward almost to Ahua Kamokukolau tilt station.

All of the,changes are pased on an assumed 0.0 change at HVO 23, a

bench mark that is about 2-1/2 miles northwest of Halemaumau.

The summit uplifted a total of 0.5 foot during the first quarter of

1967. Uplift apparently took place in surges, with shiftings of the

center of maximum inflation around various parts of the Kilauea Caldera.

Precise leveling at the summit along with the tilt data showed that:

(1) Between mid-October 1966 and January 12, 1967, the area of maximum

uplift was 0.38 foot and located about 2 km south-southeast of Halemaumau.

(2) Between January 12 and February 10 the summit uplifted an 'additional

0.2 foot and the "maximum" area shifted to about 2 kIn due south of

Halemaumau. (3) Between February 10 and February 27 the uplift amounted

to, only 0.15 foot, but the striking feature of this level run was that

it showed a change from roughly circular patterns of the past to an

elongate pattern seemingly oriented along the southwest edge of the

Caldera. (4),Between February 27 and March 30 the summit uplifted another

0.17 foot, with the maximum about 2 kIn due south of Halemaurnau. Level

data showed that the pattern had again returned to a circular pattern.

All of the structural deformation at the summit took place

apparently with no seismic activity, as the shallow Caldera earthquake

count stayed at low levels through most of the period. Tw'o flurries of

quakes from other sources did occur during this quarter. The first on

December 31, 1966, and again January 6, 7, 1967, emanated from about

30 km beneath Kilauea. The second occurred late in February and

consisted of several dozen small shallow quakes on the lower east rift

near Kapoho.

Tilting of the ground around Kilauea Caldera

Tilting of the ground around the summit of Kilauea is monitored

daily by a short-base water-tube tiltmeter at Uwekahuna (table 1), and

at irregular intervals it is measured on a regional scale by means of a

network of field tilt-bases and a portable water-tube tiltmeter (table ~).

The attitude of the ground surface at each tilt-base is reported in terms

of north-south and east-west tilt coordinates. Both coordinates at each

station were arbitrarily set equal to 500 when,measurements at that

station were begun. Increasing tilt coordinates correspond to northward

~nd eastward tilting of the earth's surface; that is, to a relative

subsidence toward the north and east. A one-unit change in coordinate

correponds to a tilting of 1 microradian (1 rom per km) in the direction

indicated.

Seismic summary

Events recorded by the U.S. Geological Survey seismograph network

in Hawaii fall into two categories: Local earthquakes and tremor

originating in the region of the Hawaiian Islands (usually within 100 km

of at least one seismograph), and distant earthquakes originating more

than 3,000 km from Hawaii. As an index of seismic activity at Hawaiian

volcanoes, daily counts of earthquakes and minutes of tremor recorded

by seismographs in Hawaii are listed in table 3. The earthquakes are

separated into groups on the basis of region of origin as determined by

analysis of records obtained daily at the Observatory (stations U, M,

M( 2), A, D, N, WP, MP, K, 0). Earthquakes of magnitude 2. a or greater

are generally sufficiently well recorded to be located with greater

precision; they are listed individually in table 4.

Location of and essential data of each seismograph station are

listed in table 5 in the first-quarter issue each year.

Acknowledgments

Several people or agencies reported ttfeltl1 earthquakes during

the first quarter, 1967. Their'assistance is gratefully acknowledged.

Table 3.--Numbers of earthquakes and minutes of tremor recorded on seismographs around Ki

Tremor is separated into three categories: deep, intermediate, and shallow, on the basis of rela

on seismographs-in the summit region. Unless otherwise stated, tremor is presumed to be associ

movement of magma within the central complex of Kilauea.

Earthquake categories are: Kilauea sumrnit, 30 krn earthquakes from a source about 30- kIn beneath t

surmnit region; long-period, earthquakes characterized by low-frequency waves that originate abo

Kilauea summit; and shallow in the Kilauea Caldera region; shallow alon

zone of Kilauea and the adjacent portion of the Kaoiki fault system; earthquakes along the east

Kilauea's east rift zone--detected largely on the Pahoa seismograph; earthquakes from the upper 

zone and the adjacent fault systems of Kilauea's south flank; and earthquakes from other region

Mauna Kea, etc.

Tilting of the ground around Kilauea Caldera

Tilting of the ground around the swmnit of K,ilauea is monitored

daily by a short-base water-tube tiltmeter at Uwekahuna (table 1), and

at irregular intervals it is measured on a regional scale by means of a

network of field tilt-bases and a portable water-tube tiltmeter. The

attitude of the ground surface at each tilt-base is reported in terms

of north-south and east-west tilt coordinates. Both coordinates at

each station were arbitrarily set equal to 500 when measurements at that

station were begun. Increasing tilt coordinates correspond to northward

and eastward tilting of the earth's surf~cej that is, to a relative

subsidence toward ,the north and east. A one-unit change' in coordinate

corresponds to a tilting of 1 microradian (1 rom perkm) in the direction

indicated.

Location of and essential data on each tiltmeter station are listed

in table 6, which is published only in the first quarter issue each year.

Seismic summary

Events recorded by the U.S. Geological S~rvey seismograph

network In Hawaii fall into two categories: Local earthquakes and

tremor originating in the region of the Hawaiian Islands (usually

within 100: km'of at least one seismograph), and distant earthquakes

originating more than 3,000 km from Hawaii. As an index of seismic

activity at Hawaiian volcanoes, daily counts of earthquakes and minutes

of tremor recorded by seismographs in Hawaii are listed in table 3.

The earthquakes are separated in groups on the basis of region of origin

as determined by analysis of records obtained daily at ,the Observatory

(U, M, M(2), A, D, N, WP, MP, 'K, 0). Earthquakes of magnitude 2.0 or

greater are generally sufficiently well recorded to be located with

greater precision; they are listed individually in table 4.

Location of and essential data on each seismograph station are

liste~ in table 5, which is published only in the first quarter issue

each year.

Table 3. 0 f earthquakes and minutes of tremor recorded on seismographs around 

Tremor is separated into .three categories: deep, intermediate, and shallow, on the basis ·of relat

on seismographs in the summit region. Unless otherwise tremor is presumed to be associa

movement· of magma within the central complex of Kilauea.

Earthquake categories are: ·Kilauea summit, 30 km earthquakes from a source about 30 km beneath th

summit region; long-period,' earthquakes characterized by waves that originate abou

Kilauea summit; and shallow earthquakes in the Kilauea Caldera region;· shallow earthquakes along

zone of Kilauea and the adjacent port.ion of the Kaoiki fault system; earthquakes along the easte

Kilauea's east rift zone--detected largely on _Pahoa seismograph; earthquakes from the upper 

zone and the adjacent fault systems of Kilauea's south flank; and earthquakes from other regions

Mauna Kea, etc'.

Tilting of the ground around Kilauea Caldera

Tilting of the ground around the summit of Kilauea is monitored

daily by a' short-base water-tube tiltmeter at Uwekahuna (table 1), and

at irregular intervals it is measured on a regional scale by means of a

network of field tilt-bases and a portable water-tube tiltmeter. The

attitude of the ground surface at each tilt-base is reported in terms

of north-south and east~west tilt coordinates. Both coordinates at

each station were arbitrarily set equal to 500 when measurements at that

station were begun. Increasing tilt coordinates correspond to northward

,and eastward tilting of the earth's surface; that is, to a relative

subsidence toward the north and east. A one-unit change in coordinate

corresponds to a tilting of 1 microradian (1 mm per kIn) in the direction

indicated.

Location of and essential data on each tiltmeter station are listed

in table 6, which is published only in the first quarter issue each year.

Seismic summary

Ev~nts recorded by the U.S. Geological Survey seismograph network

in Hawaii fall into two categories: Local earthquakes and tremor

originating in the region of the Hawaiian Islands (usually within

100 km of at least one seismograph), and distant earthquakes originating

more than ,,000 km from Hawaii .. As an index of seismic activity at

Hawaiian volcanoes, daily counts of earthquakes and minutes of tremor

recorded by seismographs in Hawaii are listed in table 3. The

earthquakes are separated in groups on the basis of region of origin

as determined by analysis of records obtained daily at the Observatory

(U, M, M(2), A, D, N, WP, MP, K, 0). Earthquakes of magnitude 2.0

or greater are generally sufficiently well recorded to be located

with greater precision; they are listed individually in table 4.

Location of and essential data on each seismograph station are

listed in table 5, which is published only in the first quarter

issue each year.

5
Table 3. --Nwnber 0 f earthquakes and minutes of tremor recorded on seismographs around Kil

Tremor is separated into three categories: deep, intermediate, and shallow, on the basis of relat

on seismographs in the summit region. Unless otherwise stated, tremor is presumed to be associa

movement of magma within the central complex of Kilauea.

Earthquake categories are: Kilauea summit, 30 km earthquakes from a source about 30 km beneath th

summit region; long-period, earthquakes characterized by low-frequency waves that originate abou

Kilauea summit; and shallow earthquakes in the Kilauea Caldera region; shallow earthquakes along 

zone of Kilauea and the adjacent portion of the Kaoiki fault system; earthquakes along the easte

Kilauea's east rift zone--detected largely on the Pahoa seismograph; earthquakes from the upper 

zone and the adjacent fault systems of Kilauea's south flank; and earthquakes from 'other regions

Mauna Kea, etc. .

Tilting of the ground around Kilauea Caldera

Tilting of the ground around the summit of Kilauea is monitored

daily by a short-base water-tube tiltmeter at Uwekahuna (table 1), and

at irregular intervals it is measured on a regional scale by means of

a network of field tilt-bases and a portable water-tube tiltmeter .. The

at~itude of the ground surface at each tilt-base is reported in terms

of north~south and east-west tilt coordinates. Both coordinates at

each station were arbitrarily set equal to 500 when measurements at

that station were begun. Increasing .tilt coordinates correspond to

northward and eastward tilting of the earth's surface; that is, to a

relative subsidence toward the north and east. A one-unit change in

coordinate corresponds to a tilting of 1 microradian (1 mm per km) in

the direction indicated.

Location of and essential data on each tiltmeter station are listed

in table 6, whicp is published only in the first quarter issue each year.

Seismic summary

Events recorded by the u.~. Geological Survey s~ismograph network

in Hawaii fall into two categories: Locai earthquakes and tremor

originating in the region of the· Hawaiian Isl~nds (usually within 0

100 km of at least one seismograph), and distant earthquakes originating

more than 3,000 km from Hawaii. ~As an index of seismic activity

at Hawaiian volcanoes, daily counts of earthquakes and minutes of

tremor recorded by seismographs in Hawaii are listed in table 3.

The earthquakes are separated in groups on the basis of region of

origin as determined by analysis of records obtained daily at the

Observatory (U, M, M(2), A, D, N, WP, MP, K, 0). Earthquakes of

magnitude 2.0 or greater are generally sufficiently well recorded

to be located with greater precision; they are listed individually in

table 4. 0

Location of and essential data on each seismograph station are

listed in table 5, which is published only in the first quarter issue

each yea~.

5
Table .3.--Number 0 f earthquakes and minutes of tremor recorded on seismographs around Kila

Tremor is separated into three categories: deep, intermediate, and shallow, on basis of relati

on seismographs in the summit region. Unless otherwise stated, tremor "is presumed to be associa

movement of magma within the central complex of Kilauea.

Earthquake categories are: Kilauea summit, 30 km earthquakes from a source 30 km beneath the 

summit region; long-period, earthquakes characterized by low-frequency waves that originate abou

Kilauea, summit; and shallow earthquakes in the Kilauea Caldera region; shallow earthquakes along 

zone of Kilauea and the adjacent portion of the Kaoiki fault system; earthquakes along the easter

Kilauea's east rift zone--detected largely on the Pahoa seismograph; earthquakes from the upper e

zone and the adjacent fault systems of Kilauea's south flank; and earthquakes from other regions

Mauna Kea, etc.
