There will be Pāhala Taiko drumming, dancing in the round with people in traditional costumes circling the tower, with singing, flutes, drums and other music. Everyone is invited to join in the dance, performed by participants from around the island. Also on tap are aikido demonstrations.
The Pāhala Hongwanji Bon Dance will be the last one at Buddhist temples around Hawai'i island during this Obon season. The Bon Dance honors those who came before, a celebration of the harvest with presentation of fresh vegetables, fruits and other foods for ancestors on the temple altar.
A traditional Hatsubon service begins at 4 p.m., followed by the dance. Keiki and adults can participate in making traditional, handmade Hachimaki headbands to wear. Food and other refreshments will be available for sale, including maki sushi. Japanese wind charms from Pāhala Hongwanji Taiko will be offered for sale.
Soto Michi Dojo will be open in the old Japanese school house on the temple grounds at with short aikido demos between 6:30 p.m. and 8 p.m., and sensei will be available to talk story about aikido and classes. Dojo members have also volunteered to clean the grounds and direct parking for the event.
This is the first Bon Dance at Pāhala since the Covid pandemic began. The address is 06-1123 Pa'au'au Pl., Pāhala.
Explosive eruptions are characterized by their impulsive onset and tend to radiate energy equally in all directions. These types of eruptions may throw rocks in all directions. At Stromboli, sustained jets have longer durations and produce a directed plume of ash and rocks away from the vent. The events are analogous to jet engine dynamics and such volcanic jetting can push ash to heights beyond international airline traffic altitudes.
This particular experiment in Italy is impractical from the perspective of long-term eruption monitoring. However, it demonstrated the ability to capture these data and identified constraints on how to design better ground networks to monitor the wide variety of eruption types. This work introduces methods for improved monitoring and detection of volcanic eruptions at United States and international volcanoes, which in turn improves situational awareness and volcanic response.
The Hawaiian Volcano Observatory currently uses UAS techniques to measure volcanic gas and conduct aerial imagery surveys to generate three-dimensional models. Experiments by other volcano scientists show that applications of UAS technology are continuing to develop and expand. If you want to learn more about experiments of this type, please check out this recent publication in Geophysical Research Letters (2023).

USING REMOTE ACOUSTIC MONITORING TO DISTINGUISH VOLCANIC STYLES is the subject of this week's Volcano Watch, written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates:
Volcanic eruptive activity may take many forms, from gently erupting basaltic fissures in Hawaii to intense explosive eruptions like those of Mount St. Helens. Volcano observatory scientists are keenly interested in understanding such events and their implications for hazards. Two types of eruptions have been the focus of recent studies at Stromboli in Italy.
Volcano observatories often use continuous remote monitoring instruments like seismometers and acoustic microphones to detect earthquakes and explosions. These types of sensors are ideal because they can monitor constantly, and scientists can apply remote detection capabilities, not unlike home alarm systems in households and businesses, to monitor activity.
To build more accurate alarms, volcano scientists work to better understand key eruption characteristics of volcanic eruptions.
In a recent study, USGS volcano observatory researchers joined international volcano scientists to examine two types of eruptive activity at Stromboli volcano, which erupts frequently.
The scientists were interested in discovering differences between discrete explosive eruptions compared to sustained eruptions (called jet eruptions for their similarity to a jet engine on a plane). The two eruption types have different implications for hazardous conditions at Stromboli. The motivation of the study is a better understanding of these events, at Stromboli, that can be applied to similar types of volcanic activity occurring around the globe.

Explosive eruptions are characterized by their impulsive onset and tend to radiate energy equally in all directions. These types of eruptions may throw rocks in all directions. At Stromboli, sustained jets have longer durations and produce a directed plume of ash and rocks away from the vent. The events are analogous to jet engine dynamics and such volcanic jetting can push ash to heights beyond international airline traffic altitudes.
From a volcano monitoring perspective, it is useful to understand the types of signatures that these events produce and how they are recorded on standard volcano monitoring networks. However, networks are hindered because seismic and acoustic sensors are almost always placed on the ground surface and are not ideal for the capture of eruption energetics into the atmosphere.
The research team working in Italy attempted to improve our understanding of eruption dynamics by placing an acoustic sensor on a small stationary Uncrewed Aircraft System (UAS, or drone) helicopter above Stromboli to capture both explosions and jet eruptions. The work revealed key features of the two event types that allow them to be easily distinguished by a sensor briefly suspended above the volcano.

HVO staff recently installed a new webcam—the B2cam—on the down-dropped block within Kīlauea caldera and east rim of Halema‘uma‘u crater. This camera view replaces that of the B1cam, which was moved east during the June 2023 Halema‘uma‘u eruption because it was being exposed to intense heat. The B2cam is located farther south than B1cam was, on a ledge that stands about 100 feet (30 meters) higher. The B2cam provides a low-angle westward view of Halema‘uma‘u crater floor.

Volcano Activity Updates: Kīlauea is not erupting. Its USGS Volcano Alert level is ADVISORY.
Active lava has not been visible within Halemaʻumaʻu crater at the summit of Kīlauea since June 19. During the week ending Thursday Aug. 31, elevated earthquake activity continued in an area south of Kīlauea’s summit caldera. Kīlauea summit tiltmeters generally showed slow inflation. A sulfur dioxide (SO2) emission rate of approximately 75 tonnes per day was measured on August 24.
Mauna Loa is not erupting. Its USGS Volcano Alert Level is at NORMAL. Webcams show no signs of activity on Mauna Loa. Seismicity remains low. Summit ground deformation rates indicate slow inflation as magma replenishes the reservoir system following the recent eruption. SO2 emission rates are at background levels.
There was one earthquake with three or more felt reports in the Hawaiian Islands during the past week: a M2.9 earthquake 3 km (2 mi) SW of Pāhala at 30 km (19 mi) depth on August 27 at 3:14 a.m. HST.
HVO continues to closely monitor Kīlauea and Mauna Loa. Visit HVO’s website for past Volcano Watch articles, Kīlauea and Mauna Loa updates, volcano photos, maps, recent earthquake information, and more. Email questions to askHVO@usgs.gov.

PHOTO STORIES FROM SATURDAY'S OPENING HOME FOOTBALL GAME FOR KA'U TROJANS are available. The Trojans lost 23 to 8 but made a comeback in the second quarter to score and succeed in a two-point conversion. They played Hawai'i Preparatory Academy's Kamakani from Waimea.
The next game is away, this Thursday at Kamehameha School in Kea'au.
