Episode 127
Seismic Shifts: Monitoring Volcanoes Across the United States
This episode centers on the critical updates regarding extreme heat warnings in Southern California and the ongoing volcanic activity in Alaska and Hawaii. We elucidate the specifics of the heat messaging from the National Weather Service, emphasizing the advisories for vulnerable populations and outdoor events as temperatures rise significantly in the Inland Empire and Coachella Valley regions. Furthermore, we delve into the heightened seismic activity at the ATKA Volcano complex in Alaska, identifying Korovin as a potential source for any explosive occurrences. Additionally, we provide insights into the current status of Kilauea in Hawaii, which remains under vigilant observation due to its elevated alert status. The episode concludes with an invitation to attend the IWCE 2026, a pivotal event for professionals in critical communications, underscoring the urgent need for preparedness and awareness in the face of environmental challenges.
Takeaways:
- Southern California is currently experiencing extreme heat, prompting various warnings from the National Weather Service.
- The Alaska Volcano Observatory has reported increased seismic activity at the ATKA Volcano complex, indicating potential explosive risks.
- Great Sitkin Volcano in Hawaii is exhibiting slow lava eruptions, necessitating ongoing monitoring and assessment of volcanic activity.
- Kilauea remains at Watch Orange level, with updates provided to ensure safety for aviation and local communities.
- We emphasize the importance of reviewing local hazard products for effective communication and planning during extreme weather events.
- The IWCE 2026 event in Las Vegas is crucial for professionals involved in critical communications, highlighting the latest advancements and tools.

Transcript
Good morning.
Speaker A: ,: Speaker A:Southern California and the lower deserts are under extreme heat messaging heading into mid week with watches warnings posted by NWS offices for parts of the Inland Empire Mountains, deserts, Coachella Valley and adjacent desert zones.
Speaker A:Agencies supporting outdoor events, vulnerable populations and utility load planning should review local NWS hazard products and heatrisk messaging for timing and locations In Alaska and Hawaii, USGS volcano monitoring updates remain operationally relevant the Alaska Volcano Observatory reports elevated activity at the ATKA Volcano complex with Korovin highlighted as most likely source if explosive activity occurs.
Speaker A:While Great Sitkin continues slow lava eruption within the Summit crater in Hawaii, Kilauea remains at Watch Orange with the Hawaiian Volcano Observatory daily update noting current status and monitoring observations in the Atlantic East Pacific basins.
Speaker A:The National Hurricane center notes no active tropical cyclones at this time and continues routine tropical weather discussions during the off season as needed.
Speaker A:I will be back after this short commercial break.
Speaker A: ructure are on the line, IWCE: Speaker A:Starting today the 16th through the 19th at the Las Vegas Convention center, the critical communications community comes together with 250 exhibitors, hands on learning and the newest thinking on LMR to broadband Convergence Next Gen 9.

Speaker A:Make your next upgrade decision with confidence.
Speaker A:Grab your pass and plan your trip now.
Speaker A:CTA link is in the show notes.
Speaker A:I hope to see you there.
Speaker A:Let's run through the states.
Speaker A:Alaska USGS AVO reports increased seismicity at the ATKA volcano complex with Koravin identified as the most likely source if explosive activity occurs.
Speaker A:Great Sitkin continues a slow lava eruption within the Summit crater with elevated seismic signals and satellite observations supporting ongoing monitoring.
Speaker A:NWS offices post extreme heat watches warnings affecting parts of Southern California desert's mountains including the Coachella Valley, San Diego county deserts and nearby zones with timing that extends into later this week.
Speaker A:Local heat messaging emphasizes limiting strenuous activity during peak heat and monitoring for heat illness.
Speaker A:Hawaii USGS HVO daily update continues for Kilauea at Watch Orange supporting ongoing situational awareness for aviation and local coordination.
Speaker A:All other states have no significant updates in the last 24 hours.
Speaker A:I hope to see you at the iwce on the 19th.
Speaker A:Stay safe.
