Ingrid A. Johanson
Ingrid is a research geophysicist at the Hawaiian Volcano Observatory. She is an expert in using GPS, as well as satellite radar data (InSAR), to measure motion of the ground surface in response to geologic events such as earthquakes and magma movement.

The 2014-2015 Pāhoa lava flow crisis at Kīlauea Volcano, Hawai‘i: Disaster avoided and lessons learned The 2014-2015 Pāhoa lava flow crisis at Kīlauea Volcano, Hawai‘i: Disaster avoided and lessons learned
Lava flow crises are nothing new on the Island of Hawai‘i, where their destructive force has been demonstrated repeatedly over the past several hundred years. The 2014–2015 Pāhoa lava flow crisis, however, was unique in terms of its societal impact and volcanological characteristics. Despite low effusion rates, a long-lived lava flow whose extent reached 20 km (the longest at Kīlauea...

Response of Global Navigation Satellite System receivers to known shaking between 0.2 and 20 Hertz Response of Global Navigation Satellite System receivers to known shaking between 0.2 and 20 Hertz
Over the past decade, several technological advances have allowed Global Navigation Satellite Systems (GNSS) receivers to have the capability to record displacements at high frequencies, with sampling rates approaching 100 samples per second (sps). In addition, communication and computer hardware and software have allowed various institutions, including the U.S. Geological Survey (USGS)...
