Product Engineer at Esri. I study cartography, volcanoes, and the cartography of volcanoes. Opinions are my own.

Eloïse Bretagne has finished her PhD thesis! This 'frontispiece' is a 3D rendering from one of her simulation results showing how melt moves through a crystal framework in a random packed magma mush. I think it's very beautiful.

King tides (the highest winter tides) are coming to the Oregon coast Jan. 20-22. Exercise extreme caution because, if we’ve said it once we’ve said it a million times: Giant waves have zero chill.

Magnífico timelapse del Halema'uma'u, donde una fisura ha cubierto de lava el suelo del cráter...

Accurate. Very, very accurate.

Ecco il video ravvicinato del flusso piroclastico principale che nel pomeriggio si è sviluppato sulla Sciara del Fuoco dello #Stromboli provocando la formazione di uno #tsunami alto 1,5 metri. Per fortuna al momento non si hanno notizie di danni.

Pictured: one of many reasons why @USGSVolcanoes is my favorite thing about Twitter.

@MechFrog12 It stays crunchy in milk. And just about every other type of liquid.

It has come to my attention that I haven't spent enough time at Cove Palisades. Worked on that today.

Just moved back to Oregon and don't yet have access to my usual carto tools, so this is my only submission for this year's #30DayMapChallenge.

I love this illustrated panoramic map for teaching about lahar hazards.

#tbt We commemorate Colombia’s Nevado del Ruiz eruption and lahar on November 13, 1985. This science note discusses the lessons learned and the work done by the Colombian Geological survey to promote volcanic risk management for new generations in Colombia https://t.co/ouDYb1kfRF

@Ogedei_Bahadur @John_M_Nelson @pokateo_ In undergrad I lost marks because I didn't use two spaces, so I did. Then in grad school I lost marks because I did, so I didn't.

Glad to be back home.

@kennethfield I was a late arrival on Twitter and barely post lately. I'm content to be a late arrival on whichever one gets most of the geoscience users departing Twitter and, optionally, grows into what those users are looking for in a Twitter replacement.

@janinekrippner We appreciate your dedication to providing this public service.

Alone in the light
above the clouds
facing the sky
far from the crowd
standing high
you should be proud
survived my fight
say it loud
