Mangaluru prone to earthquakes, says survey

May 6, 2015

Mangaluru, May 6: According to an experts survey, it has been found that buildings in Bejai-Balmatta, Attavar -Hampankatta, have not adhered to IS 1893 : 2002, Part 1, which is the criteria for earthquake resistant design of structures, NITK?Civil Engineering Department Professor D Venkat Reddy said.

He was delivering a talk on ‘Earth, oceans and coastal zone management’, organised by Institution of Engineers (India) local centre an Institution of Valuers Mangalore Branch in Mangaluru.

The city falls in seismic zone-3 which means that the quakes of intensity six could occur. The buildings could withstand the earthquakes up to five in the Richter scale. As per Indian Standards on Earthquake Engineering, IS1893:1984 criteria for Earthquake Resistant Design of Structures, the country has been categorised into five seismic zones, based on the seismic intensity. IS is about earthquake resistant design of structures and is applicable to buildings, and other structures such as bridges, dams etc. Earthquakes of magnitude of eight take place in zone five. Nethravathi and Gurupur river basins are tectonically active.

As observed in Nepal, the structural failure of buildings have caused more amount of damage. In contrast, the Pashupathinath Temple is intact, though the building in its surrounding have been badly effected, which is due to the difference in structural pattern.

He further said that seismic waves alone are not responsible . Seismic activities take place round the clock. The earthquakes take place due to the sudden failure of strata. As per an estimation, around one thousand take place across the world everyday and three of them could be serious.

A lineament which is a fault in the underlying geological structure and the constructions on these lineaments such as railway tracks, bridges etc could cause more danger. IIS?has established a network system which records the seismic activities and which can even record 0.1 mm change in the crest of the earth. As per the movement of earth plates, a region will be displaced in a span of hundred years.

I'm building a 1story house with slab on load bearing walls instead of the concrete frame structure. Will this be resistant agaianst earthquakes?

Mangaluru police have arrested a 27-year-old NRI on his return from Saudi Arabia in connection with an Instagram post allegedly containing derogatory and provocative remarks about the Hindu religion, officials said on Monday.

The accused, Abdul Khader Nehad, a resident of Ulaibettu in Mangaluru, was working in Saudi Arabia when the post was uploaded, police said.

A suo motu case was registered at the Bajpe police station on October 11 after an allegedly offensive post circulated from the Instagram account ‘team_sdpi_2025’. Police said the content was flagged for being provocative and derogatory in nature.

During the investigation, technical analysis traced the Instagram post to Nehad, who was residing abroad at the time, a senior police officer said. Based on these findings, a Look Out Circular (LOC) was issued against him.

On December 14, Nehad arrived from Saudi Arabia at Calicut International Airport in Kerala, where he was taken into custody on arrival. Police said further investigation is underway.

Mangaluru, Dec 7: A rare bamboo shrimp has been rediscovered on mainland India more than 70 years after it was last reported, confirming for the first time the presence of Atyopsis spinipes in the country. The find was made by researchers from the Centre for Climate Change Studies at Sathyabama Institute of Science and Technology, Chennai, during surveys in Karnataka and Odisha.

The team — shrimp expert Dr S Prakash, PhD scholar K Kunjulakshmi, and Mangaluru-based researcher Maclean Antony Santos — combined field surveys, ecological assessments and DNA analysis to identify the elusive species. Their findings, published in Zootaxa, resolve decades of taxonomic confusion stemming from a 1951 report that misidentified the species as Atyopsis moluccensis without strong evidence.

The shrimp has now been confirmed at two locations: the Mulki–Pavanje estuary near Mangaluru and the Kuakhai River in Bhubaneswar. Historical specimens from the Andaman Islands, previously labelled as A. moluccensis, were also found to be misidentified and actually belong to A. spinipes.

The rediscovery began after an aquarium hobbyist in Odisha spotted a shrimp in 2022, prompting systematic surveys across Udupi, Karwar and Mangaluru. Four female specimens were collected in Mulki and one in Odisha, all genetically matching.

Researchers warn the species may exist in very small, vulnerable populations as freshwater habitats face increasing pressure from pollution, sand mining and infrastructure development. All verified specimens have been deposited with the Zoological Survey of India for future reference.

Mangaluru, Dec 15: Educational institutions in Mangaluru that rely on the popular Mangala Stadium for their annual sports events are bracing for an inconvenience as the city's key sporting venue is set to close its gates for a significant upgrade. The stadium is expected to be unavailable for approximately two months starting from January 15, 2026.

The closure is necessitated by a proposed overhaul of the stadium's facilities, with a special focus on upgrading the synthetic track. Pradeep Dsouza, Assistant Director of the District of Youth Empowerment and Sports (DYES), Dakshina Kannada, confirmed the development.

"Experts have visited the stadium, conducted a thorough inspection, and have given the go-ahead for a complete makeover," Dsouza stated. "Funds have been allocated for the project, and we are currently awaiting the final green signal from state officials to commence the work. We anticipate that the work will likely begin in the second week of January. Consequently, we have stopped renting out the stadium to colleges and other organizations in preparation for the upgrade."

The timing presents a logistical challenge for colleges, as many schools have already concluded their sports meets.

"Colleges will now be organizing their events and will need to find alternative locations to host their sports meets," Dsouza added. He suggested a few potential venues, including the Dakshina Kannada police ground, University College grounds, Panambur grounds, Swaraj Maidan in Moodbidri, and the Mangalore University sports grounds in Konaje.

However, many institutions note that finding a comparable venue will be difficult. While the DK police ground and University College grounds are closer to the city center, they do not possess the extensive facilities and infrastructure offered by Mangala Stadium.

Dr. P Dayananda Pai - P Satisha Govt First Grade College, Carstreet, is one such institution dependent on the stadium. Principal Jayakar Bhandary expressed hope for a swift completion of the work. "We expect the work to be completed at the earliest. If not, we will be forced to look for other venues to host the sports day for our students," Bhandary said, highlighting the pressing need for the city's main sporting facility.
