(All four network-affiliated TV stations (KRON, KGO, KTVU and CBS affiliate KPIX) would recover enough to broadcast continuous breaking news coverage of the aftermath of the quake for the next several hours, some of it picked up and broadcast nationally over their respective networks, as well as on CNN, in a manner anticipating later major catastrophes such as the 1994 Los Angeles earthquake and the 9/11 terror attacks). Qf Ml@DEHb!(`HPb0dFJ|yygs{. The duration of the heaviest shaking in the Santa Cruz Mountains was about 15 seconds, but strong ground motion recordings revealed that the duration of shaking was not uniform throughout the affected area (because of different types and thicknesses of soil). that more people would have died had it not been for the World Series as many were watching the game rather than sitting in traffic on freeways, where most of the casualties occurred. Rush-hour traffic on the Bay Area freeways was lighter than normal because the game, being played at Candlestick Park in San Francisco, was about to begin, and this may have prevented a larger loss of life, as several of the Bay Area's major transportation structures suffered catastrophic failures. Since the bay was only two blocks from the burning buildings,[53] water from the bay was pumped by the fireboat Phoenix, to engines on the shore, and from there sprayed on the fire.

With an Mw magnitude Expert Answer. some of the seismometers displayed non-linear effects from the strong [40] Many San Francisco radio and television stations were temporarily knocked off the air. Unlike other nearby (high gain) seismographs that were overwhelmed (driven off scale) by the large magnitude mainshock, the four accelerometers captured a useful record of the main event and more than half an hour of the early aftershock activity. 1)The 1989 Loma Prieta Earthquake For example, the 1964 Niigata earthquake caused widespread liquefaction in Niigata, Japan which destroyed many buildings.
