Kilauea volcano (Hawai'i): earthquake swarm near summit caldera

Location of today's quakes (red) near the summit of Kilauea volcano

A swarm of small shallow earthquakes has been occurring today in an area 2-3 miles northwest of the summit caldera, near the Highway 11.
So far, almost 50 quakes of magnitudes between 1.7 and 3.0 have been recorded by USGS, at shallow depths mostly around 2-3 km.
Whether the quakes are related to magmatic processes or are purely tectonic in origin is unclear; USGS has not yet commented on the events. The largest tremor, a magnitude 3.0 quake 9 Km WSW at 1.43 am local time, was felt by some residents of Volcano village.

Hawaii’s Kīlauea Volcano – an exaggeration of the truth

To capture the public's attention, some news articles occasionally over-exaggerate on the scientific truth, elaborating on evidence and observation. Is the Halema'uma'u Crater within Kīlauea Volcano really “turning into a deadly crater lake?” as portrayed in a recent Forbes article and thus triggering similar eye-catching news stories. One article claims “the volcano is quickly turning into a crater lake full of lava” - a statement that is very misleading and, scientifically, inaccurate for the volcano in question. ... Read all

Kilauea volcano (Hawai'i): HVO monthly update

The growth of the water pond at Halema'uma'u (C) U.S, Geological Survey

The Hawaiian Volcano Observatory (HVO) report that over the past month at Kilauea volcano, the rates of seismicity varied but within a range observed over the past year. Sulfur dioxide emission rates have been low at the summit and below detection limits at Puʻu ʻŌʻō and the lower East Rift Zone. The water pond at the bottom of Halema'uma'u continues to slowly expand and deepen and its dimensions are approximately 100 meters (330 feet) by 200 meters (660 feet) and approximately 28 meters or 92 feet deep as of early March. ...

Kilauea volcano (Hawai'i): HVO monthly update

Kilauea caldera captured from HVO's KWcam (C) U.S. Geological Survey

Over the past month, rates of seismicity were variable but within long term vales. Sulfur dioxide emission rates are low at the summit and are below detection limits at Puʻu ʻŌʻō and the lower East Rift Zone. The pond at the bottom of Halema'uma'u, which began forming on July 25, 2019, continues to slowly expand and deepen. The pond has grown 95 meters by 194 meters (310 feet by 640 feet) and 25 meters (82 feet) deep. The pond has deepened by 2 meters (around 7 feet) over the month of January 2020. ... Read all

Kilauea volcano (Hawai'i): HVO monthly update, December 2019

The Hawaiian Volcano Observatory (HVO) note that the rates of seismicity over the month of December 2019 were variable but within long term vales. Sulfur dioxide emission rates were low at the summit and were below detection limits at Puʻu ʻŌʻō and the lower East Rift Zone. The pond at the bottom of Halema'uma'u crater, which began forming on July 25, 2019, continues to slowly expand and deepen. As of early January 2020, the dimensions of the pond are 84 meters by 190 meters (280 feet by 620 feet). Current depth is about 23 meters (75 feet). ... Read all

Kilauea volcano (Hawai'i): HVO monthly update

The Hawaiian Volcano Observatory (HVO) report that their monitoring data have shown no significant changes in volcanic activity during November. Over the past month, about a dozen DI (Deflation-Inflation) events occurred beneath the summit. Over 1800 earthquakes were detected in the vicinity of the volcano, which is an increase of around 10% from last month. Rates of seismicity are relatively consistent throughout the month, although at the summit, episodic increased rates appear to be coincident with the inflated phase of the DI events. Sulfur dioxide emission rates are low at the summit and are below detection limits at Puʻu ʻOʻo and the lower East Rift Zone. The pond at the bottom of Halema'uma'u, which began forming on July 25, 2019, continues to slowly expand and deepen, and the most recent measurements are 162 meters in the east-west direction and 73 meters in the north-south direction. ...
