With recent attention focused on the need to be prepared for all hazards, this week’s Volcano Watch offers ways to stay informed about Hawaiian volcanoes and earthquakes.

Today’s smartphones and 24/7 news coverage provide an ever-increasing number of ways to follow what’s happening in the world of natural hazards, including volcanoes and earthquakes. For some, this barrage of information is challenging. But others might argue that offering hazards information in a variety of ways reaches a broader audience more quickly and efficiently.

Whatever your preference, there are several ways that Hawai‘i residents, visitors, and public safety officials, as well as volcano fans around the globe, can follow what’s happening at Hawaiian volcanoes.

Let’s review the options to find what works for you.

First and foremost, the US Geological Survey’s Hawaiian Volcano Observatory website is available 24/7 for people with access to the Internet. On this website you can find daily eruption updates for Kīlauea and weekly updates for Mauna Loa. There are also links to photographs, videos, maps, webcams, monitoring data, Volcano Watch articles, news releases, frequently asked questions, and much more.

Updates on Hawaiian volcanoes, HVO’s weekly “Volcano Watch” articles, and other volcano postings can also be followed via social media, including Facebook and Twitter.

If HVO’s website and Internet searches do not yield the information you’re seeking, you can email [email protected] to inquire about Hawaiian volcanoes and earthquakes. HVO strives to answer all askHVO email inquiries.

For people who want information sent to them directly and automatically, day or night, the US Geological Survey offers two notification services: one for volcanoes and one for earthquakes. Hawai‘i residents interested in rapid notifications about volcanic and seismic activity are encouraged to sign up for both (more than 11,000 subscribers currently receive HVO notices). Here’s how:

The USGS Volcano Notification Service is a free, customizable email-subscription service that delivers notifications of significant volcanic activity directly to your inbox or cell phone. You can sign up for this service here.

With the VNS, you can choose from various types of notifications—Updates (daily, weekly, or monthly), Status Reports, Volcano Activity Notices, and/or Information Statements. You can also select whether you want to receive notices only from HVO about specific Hawaiian volcanoes, and/or notices about other US volcanoes in the Cascades, Alaska, California, and at Yellowstone.

The USGS Earthquake Notification Service is a similar subscription service for information about earthquakes that occur in Hawaii and elsewhere in the world. The ENS can be customized to deliver messages about earthquakes of particular magnitudes, at specified times, and via your preferred method (email or text). You can sign up for this free service here.

Not everyone is connected to the Internet. For those folks, tuning into local radio stations or watching your favorite Hawai‘i television news source are good ways to keep informed about important changes at Hawaiian volcanoes. This is especially true during volcanic and earthquake emergencies, when Hawai‘i County Civil Defense proactively issues messages via public media about any situation that could impact public safety.

HVO also maintains short, recorded telephone messages about Kīlauea’s recent eruption activity and Mauna Loa’s current status. Call 808-967-8862 (for daily Kīlauea updates) or 808-967-8866 (for weekly Mauna Loa updates) at any time to hear these messages.

Hawai‘i Volcanoes National Park also provides online information through its “What’s going on with the volcano?” webpage, which includes links to HVO updates, as well as National Park Service and USGS photos and videos. This webpage also provides visitor information on viewing lava safely.

Volcano Awareness Month—held each January, during which HVO scientists offer programs about Hawaiian volcanoes—is a great way to stay informed. Details about upcoming events are posted on HVO’s website, or you can email [email protected] or call 808-967-8844 for more info.

Recently, Kīlauea Volcano’s two ongoing eruptions have been relatively steady, but long-time volcano watchers know this could change at any time. An eruption of Mauna Loa is not imminent, but it is an active volcano that will erupt again.

Volcano Activity Updates

This past week, Kīlauea Volcano’s summit lava lake level fluctuated with summit inflation and deflation, ranging about 85–121 ft below the vent rim. On the East Rift Zone, the 61g lava flow remained active downslope of Pu‘u ‘Ō‘ō, with scattered breakouts on the pali and coastal plain, but no ocean entry. The 61g flows do not pose an immediate threat to nearby communities.

Mauna Loa is not erupting. Rates of deformation and seismicity remain above long-term background levels, but rates are decreased from earlier in the year. Similar decreases have occurred in the past during the ongoing period of unrest; it is uncertain if these lower rates will persist or will pick up again in the near future. Small-magnitude earthquakes occurred beneath the summit caldera and upper Southwest Rift Zone at depths less than 3 miles. A few deeper earthquakes were scattered beneath the volcano’s southeast and west flanks at depths less than 8 miles. GPS and InSAR measurements continue to show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone. No significant changes in volcanic gas emissions were measured.

No earthquakes were reported felt on the Island of Hawai‘i this past week.
