Meet Pnina Miller
Seismologist (someone who studies vibrations in the earth.
Her Job: Setting up seismic stations for researchers
This is a photo of Pnina at a seismic station set up at the South Pole!
Most people don’t get paid to watch explosions set off by scientists. But it’s all part of the job for Dr. Pnina Miller. She works at PASSCAL where they set up equipment for scientists to
study movements in the earth. It's a bit like a library, but instead of books, scientists check out seismic equipment. They use it to measure changes in ground motion. Scientists use the data to study earth’s layers, earthquakes, volcanoes, and even glaciers, which are slow-moving sheets of ice. For some of these projects, Pnina goes along to set up the equipment and make sure it's working correctly. Click here to explore this interactive map
Some scientists use the equipment to study natural ground motion from earthquakes or volcanoes. But sometimes the scientists have to make the ground move. They might use explosives. They might use giant trucks that pound the ground as they move. They might force water into cracks in the earth. What they learn from their study helps us understand earth processes. Some experiments help us understand tectonic plates. some experiments help us understand global warming.
Pnina's work has taken her from Alaska to the south pole, all the way around the globe. She's worked on every continent. Here are just a few of the places she has worked.
Pnina likes that her job includes so many people. She works with electricians, mechanical engineers, seismologists, computer programmers, and people who organize the lending and travel.
Pnina’s advice to anybody who wants to work in science is to go outside and look at the world. Take a field trip to your backyard. Be curious. Ask questions. What is this? Why is it here and not there? Don’t settle for a simple answer. Want to know more.
