Small Earthquake at Summit of Pu’u O’o – Lava Flows Onto Floor of Crater

A small earthquake of magnitude 3.6 occurred yesterday evening at 6 p.m. near the summit of the volcano. Over the past 24 hours, small amounts of lava flowed onto the floor of Puʻu ʻŌʻō.

Webcam images show that small amounts of lava flowed onto the crater floor from two of the incandescent vents within the Puʻu ʻŌʻō crater. Yesterday, shortly before noon, and at around 10 p.m., lava flowed onto the floor from a vent on the east side of the crater, while this morning at around 6 a.m., lava flowed from one of the vents on the west side of the crater.

This current image is from a temporary thermal camera positioned on the northwest flank of Puʻu ʻŌʻō, looking southeast at Puʻu ʻŌʻō's summit crater.  The temperature scale is in degrees Celsius up to a maximum of 500 degrees (932 degrees Fahrenheit) for this camera model, and scales automatically based on the maximum and minimum temperatures within the frame.  Thick fume, image pixel size and other factors often result in image temperatures being lower than actual surface temperatures.

Mauna Loa Weekly Earthquake Rates Since 2010

Yesterday, Hawaii Volcano Observatory elevated the advisory level for Mauna Loa and now folks all over the Big Island are wondering when and if she will erupt again!

Here are the Mauna Loa weekly earthquake rates between 2010 and September 17, 2015.

mauna loa earthquake rates
TOP: Blue bars indicate the number of earthquakes that were located by the USGS Hawaiian Volcano Observatory seismic network. Earthquakes of all magnitudes are plotted. Subtle increases in earthquake rates started in mid-2013, while more obvious changes in rates started in 2014.

BOTTOM: Change in distance across Mauna Loa’s summit caldera between 2010 and September 17, 2015. Blue dots indicate the relative distance between two stations that span the summit caldera of Mauna Loa, shown in the map on the upper left. Sustained extension across the caldera started in mid-2014. This extension is one of the indicators of magma infilling a complex reservoir system beneath the summit and upper Southwest Rift Zone.

Big Island Earthquake Upgraded to 5.2 Magnitude

The earthquake that happened yesterday evening has been upgraded to a 5.2 magnitude earthquake.

This follows a previous update of 5.0 and 4.9 as previously reported.

18 Earthquakes Swarm Summit Where Lava is Coming From

18 earthquakes were registered within a few minutes of each other early this morning near the Pu’u O’o crater!

 

Summit Observations: Weak inflationary ground tilt recorded at the summit over the past 3+ days continued to weaken. There was a swarm of earthquakes in the upper east rift zone early this morning; 18 quakes occurred within a few minutes of 1 am.

11015earthquakesThe summit lava lake has shown minor fluctuations associated with changes in spattering behavior, which are also manifested as variations in tremor amplitudes and gas release but no net change in level which was measured at around 48 m (160 ft) below the lip of the Overlook crater Tuesday morning.

Small amounts of particulate material were carried aloft by the plume. The average emission rate of sulfur dioxide was around 5,400 tonnes/day for the week ending on January 6.

Rockfall Triggers Explosive Event at Halema’uma’u

Just after 10 AM this morning, the southeastern wall of the Overlook crater, in Halemaʻumaʻu, collapsed and fell into the summit lava lake.

This image is a still taken from the webcam positioned on the rim of Halemaʻumaʻu at that location, showing spatter in the air directly in front of the camera.

This triggered a small explosive event that threw spatter bombs onto the rim of Halemaʻumaʻu at the site of the tourist overlook, closed since 2008.

The lava fragments ejected ranged in size from dust-sized particles up to spatter bombs about 70 cm (~30 inches) across.

The larger clasts – the bombs – dotted the ground around the tourist overlook and webcam, giving the area a look reminiscent of a cow pasture.

As has been seen with almost all previous explosive events at Halemaʻumaʻu since 2008, the spatter that was ejected was coated in dust and filled with small lithic fragments – clear evidence of the involvement of lithic wall rock.

The knife is 12 cm (4.5 in) long.

Spatter landed on wooden fencing laying on the ground at the closed tourist overlook, igniting it in a few places.

HI-EMA Encourages Public to Update Emergency Notification Service

The Hawaii Emergency Management Agency (HI-EMA), formerly known as State Civil Defense, encourages members of the public to sign up for local emergency notifications provided by county civil defense and emergency management agencies.

Department of DefenseInstructions for island-specific systems are available at:

On June 30, 2014, Sprint Relay Hawaii discontinued its emergency notification system that the company had been providing free of charge for 6 years. Relay Hawaii was designed to provide Short Message Service (SMS)/text messages on natural disasters and other emergencies to the deaf and hard of hearing community.

“Sprint Relay Hawaii has been a terrific partner in providing warning of approaching hazards and emergencies, and we are grateful for the services it provided,” said Doug Mayne, Administrator for Emergency Management. “Individuals are urged to update notice subscriptions with alternatives. Having a reliable way to get information on local dangers is crucial to making sure an emergency doesn’t turn into a disaster.”

Wireless Emergency Alerts (WEA) are also available through the federal government for people with WEA-enabled phones. Go to http://www.ready.gov/alerts for more information.
