A magnitude 3.8 earthquake, with a hypocenter 600 meters directly under the field, struck in the early hours of March 3, 2022. [29] Despite the increases in the number of earthquakes and the fears of local residents, it is unlikely that a large earthquake will occur at the Geysers since there is no fault or fracture nearby. [8]
Further earthquakes in 2000 revived the geyser, [15] and it reached 122 meters for two days. [citation needed], thus becoming one of the highest known geysers in history. Waimangu Geyser in New Zealand typically erupted higher than this, up to 460 m (1,510 ft) high, [16] but it stopped all activity around 1908.
Studies have shown that injecting water into The Geysers field produces earthquakes from magnitude 0.5 to 3.0, although a 4.6 occurred in 1973 and magnitude four events increased thereafter.

About 250 people from as far away as Nice and San Francisco reported feeling the largest tremor to USGS.
A sand geyser, sand fountain or sand blow is a geologic phenomenon which occurs in association with earthquakes and other seismic events. [1] In the geologic record, these are seen as clastic dikes. [2] It is described as "a geyser of sand and water that shoots from the ground during a major earthquake."
"Without legitimate oversight of underground injection in Texas, we expect more geyser-like well blowouts, sinkholes, leaks from plugged and unplugged wells, and injection-induced earthquakes ...
Earthquakes at the Geysers geothermal field in California, the largest being Richter magnitude 4.6, have been linked to injected water. [39] "Possible effects include scenery spoliation, drying out of hot springs, soil erosion, noise pollution, and chemical pollution of the atmosphere and of surface- and groundwaters." [40]
Strokkur was first mentioned in 1789, after an earthquake helped to unblock the conduit of the geyser. Its activity fluctuated throughout the 19th century; in 1815 its height was estimated to have been as much as 60 metres (200 ft). It continued to erupt until the turn of the 20th century, when another earthquake blocked the conduit again.
