This chart is only as updated as the DoH makes the data available - generally it is within the hour... sometimes not. It is also ONLY the Particulates - NOT the SO2


Here's the latest DoH site - it is usually a little late - Watch the times!!!

1 ppm  = 1000 ppb
 1part per million = 1000 parts per billion

VMAP SO4 / Particulate Predictions

The Department of Health's SO2 & Particulate monitoring station in Pahala - 2008,
alongside Ka'u High School



Pahala Monitoring Station

The building that houses the Pahala monitoring station


Where the air samples come in



Air is pulled in from above the roof and into the SO2 and Particulate sensors


The computer that logs the data, phones out alerts, and
is automatically called to download the previous 15 minutes
data. Along with backup data storage.



Tbe SO2 sensor and calibration system


The Particulate sensor
Typically, the particulates are what you see as the haze,
the SO2 is what you "taste" as the SO2 reacts with
the moisture in your mouth and nose to form an acid.

Just because you can see the haze, doesn't mean you
are getting SO2. Likewise, you can be exposed to SO2,
even if you can't see it.

Finally, the DoH SO2 meter has been limited to 1000ppb
(parts per billion) or 1ppm (part per million). Alas, we've seen
levels at 9000ppb (9ppm) which is considered to be very bad.
There may have been even higher levels not recorded by DoH!

As of (3-Dec-08) The Pahala, Mountain View and Hilo stations
were upgraded to register 10ppm / 10,000ppb!!

The MIT Sensor setup
Now on top of M101
And NOW Sending out Data
The MIT Sensor Box

The Outside of the Box ^

And the Inside of the Box ->

A solar panel powers it, data goes out via the cell system
And there are sensors for SO2, PM 2.5 and PM 10

Inside the box
Thanks MIT folks, District Superintendant (holding the ladder below), Mark Pocock (KHS security/safety and lots of other campus jobs), Kohala Center, Principal Beck and all the rest!!!

 (Now) HISTORICAL Information


SO2 from Halemaumau


SO2 from Halemaumau - new calibration


SO2 Data has now been split into two charts

The first one is 28-Feb-08 to  28-Oct-13 and represents the first measurement / instrument

The second is from 31-Dec-13 to as recently as I've updated it :-) The data is a little glitch as they occasionally reported a Max/Min for a date
and I entered both in with the same date - excel then graphed it a little odd. I will probably go back and delete the Min values and re-graph.
The data on this, from an updated instrument has a higher value - it's the "same" amount of SO2, the volcano did not push out more gas, the measurement got better.

Data collected from the Hawaii Volcano Observatory - Eruption Update


SO2 data is not collected every day, it depends upon the weather. Sometimes the data isn't taken for a number of days.
 If you need the excel spreadsheet, send me an e-mail (easier than using the HVO archive function and entering it yourself).
The next step is to take the data from the PA16 site and map it onto this graph... Sounds like a student project!

Currently, The Eruption Update is not listing SO2 values - AND - the Summit based SO2 levels are very low!
Most SO2 / LAZE and all - as of July 2018 - is coming out of the Lower Puna eruption and ocean entry region.
